Release Notes
===============
v12.0.2 Luminous (dev)
======================
This is the third development checkpoint release of Luminous, the next long term
stable release.
Major changes from v12.0.1
--------------------------
* The original librados rados_objects_list_open (C) and objects_begin
(C++) object listing API, deprecated in Hammer, has finally been
removed. Users of this interface must update their software to use
either the rados_nobjects_list_open (C) and nobjects_begin (C++) API or
the new rados_object_list_begin (C) and object_list_begin (C++) API
before updating the client-side librados library to Luminous.
Object enumeration (via any API) with the latest librados version
and pre-Hammer OSDs is no longer supported. Note that no in-tree
Ceph services rely on object enumeration via the deprecated APIs, so
only external librados users might be affected.
The newest (and recommended) rados_object_list_begin (C) and
object_list_begin (C++) API is only usable on clusters with the
SORTBITWISE flag enabled (Jewel and later). (Note that this flag is
required to be set before upgrading beyond Jewel.)
* CephFS clients without the 'p' flag in their authentication capability
string will no longer be able to set quotas or any layout fields. This
flag previously only restricted modification of the pool and namespace
fields in layouts.
* CephFS directory fragmentation (large directory support) is enabled
by default on new filesystems. To enable it on existing filesystems
use "ceph fs set <fs_name> allow_dirfrags".
* CephFS will generate a health warning if you have fewer standby daemons
than it thinks you wanted. By default this will be 1 if you ever had
a standby, and 0 if you did not. You can customize this using
``ceph fs set <fs> standby_count_wanted <number>``. Setting it
to zero will effectively disable the health check.
* The "ceph mds tell ..." command has been removed. It is superceded
by "ceph tell mds.<id> ..."
* RGW introduces server side encryption of uploaded objects with 3 options for
the management of encryption keys, automatic encryption (only recommended for
test setups), customer provided keys similar to Amazon SSE KMS specification &
using a key management service (openstack barbician)

v12.0.1 Luminous (dev)
======================
This is the second development checkpoint release of Luminous, the next long term
stable release.
Major changes from 12.0.0
-------------------------
* The original librados rados_objects_list_open (C) and objects_begin
(C++) object listing API, deprecated in Hammer, has finally been
removed. Users of this interface must update their software to use
either the rados_nobjects_list_open (C) and nobjects_begin (C++) API or
the new rados_object_list_begin (C) and object_list_begin (C++) API
before updating the client-side librados library to Luminous.
Object enumeration (via any API) with the latest librados version
and pre-Hammer OSDs is no longer supported. Note that no in-tree
Ceph services rely on object enumeration via the deprecated APIs, so
only external librados users might be affected.
The newest (and recommended) rados_object_list_begin (C) and
object_list_begin (C++) API is only usable on clusters with the
SORTBITWISE flag enabled (Jewel and later). (Note that this flag is
required to be set before upgrading beyond Jewel.)
* CephFS clients without the 'p' flag in their authentication capability
string will no longer be able to set quotas or any layout fields. This
flag previously only restricted modification of the pool and namespace
fields in layouts.
* The rados copy-get-classic operation has been removed since it has not been
used by the OSD since before hammer. It is unlikely any librados user is
using this operation explicitly since there is also the more modern copy-get.
* The RGW api for getting object torrent has changed its params from 'get_torrent'
to 'torrent' so that it can be compatible with Amazon S3. Now the request for
object torrent is like 'GET /ObjectName?torrent'.

v12.0.0 Luminous (dev)
======================
This is the first development checkpoint release of Luminous series, the next
long term release. We're off to a good start to release Luminous in the spring
of '17.
Major changes from Kraken
-------------------------
* When assigning a network to the public network and not to
the cluster network the network specification of the public
network will be used for the cluster network as well.
In older versions this would lead to cluster services
being bound to 0.0.0.0:<port>, thus making the
cluster service even more publicly available than the
public services. When only specifying a cluster network it
will still result in the public services binding to 0.0.0.0.
* Some variants of the omap_get_keys and omap_get_vals librados
functions have been deprecated in favor of omap_get_vals2 and
omap_get_keys2. The new methods include an output argument
indicating whether there are additional keys left to fetch.
Previously this had to be inferred from the requested key count vs
the number of keys returned, but this breaks with new OSD-side
limits on the number of keys or bytes that can be returned by a
single omap request. These limits were introduced by kraken but
are effectively disabled by default (by setting a very large limit
of 1 GB) because users of the newly deprecated interface cannot
tell whether they should fetch more keys or not. In the case of
the standalone calls in the C++ interface
(IoCtx::get_omap_{keys,vals}), librados has been updated to loop on
the client side to provide a correct result via multiple calls to
the OSD. In the case of the methods used for building
multi-operation transactions, however, client-side looping is not
practical, and the methods have been deprecated. Note that use of
either the IoCtx methods on older librados versions or the
deprecated methods on any version of librados will lead to
incomplete results if/when the new OSD limits are enabled.
* In previous versions, if a client sent an op to the wrong OSD, the OSD
would reply with ENXIO. The rationale here is that the client or OSD is
clearly buggy and we want to surface the error as clearly as possible.
We now only send the ENXIO reply if the osd_enxio_on_misdirected_op option
is enabled (it's off by default). This means that a VM using librbd that
previously would have gotten an EIO and gone read-only will now see a
blocked/hung IO instead.
* When configuring ceph-fuse mounts in /etc/fstab, a new syntax is
available that uses "ceph.<arg>=<val>" in the options column, instead
of putting configuration in the device column. The old style syntax
still works. See the documentation page "Mount CephFS in your
file systems table" for details.

v11.2.0 Kraken
==============
This is the first release of the Kraken series. It is a stable
release that will be maintained with bugfixes and backports until the
next stable release, Luminous, is completed in the Spring of 2017.
Major Changes from Jewel
------------------------
- *RADOS*:
* The new *BlueStore* backend now has a stable disk format and is
passing our failure and stress testing. Although the backend is
still flagged as experimental, we encourage users to try it out
for non-production clusters and non-critical data sets.
* RADOS now has experimental support for *overwrites on
erasure-coded* pools. Because the disk format and implementation
are not yet finalized, there is a special pool option that must be
enabled to test the new feature.  Enabling this option on a cluster
will permanently bar that cluster from being upgraded to future
versions.
* We now default to the AsyncMessenger (``ms type = async``) instead
of the legacy SimpleMessenger.  The most noticeable difference is
that we now use a fixed sized thread pool for network connections
(instead of two threads per socket with SimpleMessenger).
* Some OSD failures are now detected almost immediately, whereas
previously the heartbeat timeout (which defaults to 20 seconds)
had to expire.  This prevents IO from blocking for an extended
period for failures where the host remains up but the ceph-osd
process is no longer running.
* There is a new ``ceph-mgr`` daemon.  It is currently collocated with
the monitors by default, and is not yet used for much, but the basic
infrastructure is now in place.
* The size of encoded OSDMaps has been reduced.
* The OSDs now quiesce scrubbing when recovery or rebalancing is in progress.
- *RGW*:
* RGW now supports a new zone type that can be used for metadata indexing
via ElasticSearch.
* RGW now supports the S3 multipart object copy-part API.
* It is possible now to reshard an existing bucket. Note that bucket
resharding currently requires that all IO (especially writes) to
the specific bucket is quiesced.
* RGW now supports data compression for objects.
* Civetweb version has been upgraded to 1.8
* The Swift static website API is now supported (S3 support has been added
previously).
* S3 bucket lifecycle API has been added. Note that currently it only supports
object expiration.
* Support for custom search filters has been added to the LDAP auth
implementation.
* Support for NFS version 3 has been added to the RGW NFS gateway.
* A Python binding has been created for librgw.
- *RBD*:
* RBD now supports images stored in an *erasure-coded* RADOS pool
using the new (experimental) overwrite support. Images must be
created using the new rbd CLI "--data-pool <ec pool>" option to
specify the EC pool where the backing data objects are
stored. Attempting to create an image directly on an EC pool will
not be successful since the image's backing metadata is only
supported on a replicated pool.
* The rbd-mirror daemon now supports replicating dynamic image
feature updates and image metadata key/value pairs from the
primary image to the non-primary image.
* The number of image snapshots can be optionally restricted to a
configurable maximum.
* The rbd Python API now supports asynchronous IO operations.
- *CephFS*:
* libcephfs function definitions have been changed to enable proper
uid/gid control. The library version has been increased to reflect the
interface change.
* Standby replay MDS daemons now consume less memory on workloads
doing deletions.
* Scrub now repairs backtrace, and populates `damage ls` with
discovered errors.
* A new `pg_files` subcommand to `cephfs-data-scan` can identify
files affected by a damaged or lost RADOS PG.
* The false-positive "failing to respond to cache pressure" warnings have
been fixed.
Upgrading from Kraken release candidate 11.1.0
----------------------------------------------
* The new *BlueStore* backend had an on-disk format change after 11.1.0.
Any BlueStore OSDs created with 11.1.0 will need to be destroyed and
recreated.
Upgrading from Jewel
--------------------
* All clusters must first be upgraded to Jewel 10.2.z before upgrading
to Kraken 11.2.z (or, eventually, Luminous 12.2.z).
* The ``sortbitwise`` flag must be set on the Jewel cluster before upgrading
to Kraken. The latest Jewel (10.2.4+) releases issue a health warning if
the flag is not set, so this is probably already set. If it is not, Kraken
OSDs will refuse to start and will print and error message in their log.
* You may upgrade OSDs, Monitors, and MDSs in any order. RGW daemons
should be upgraded last.
* When upgrading, new ceph-mgr daemon instances will be created automatically
alongside any monitors. This will be true for Jewel to Kraken and Jewel to
Luminous upgrades, but likely not be true for future upgrades beyond
Luminous. You are, of course, free to create new ceph-mgr daemon instances
and destroy the auto-created ones if you do not with them to be colocated
with the ceph-mon daemons.
BlueStore
---------
BlueStore is a new backend for managing data stored by each OSD on the directly
hard disk or SSD. Unlike the existing FileStore implementation, which makes
use of an XFS file system to store objects as files, BlueStore manages the
underlying block device directly. Implements its own file system-like on-disk
structure the is designed specifically for Ceph OSD workloads. Key features
of BlueStore include:
* Checksums on all data written to disk, with checksum verifications on all
reads, enabled by default.
* Inline compression support, which can be enabled on a per-pool or per-object
basis via pool properties or client hints, respectively.
* Efficient journaling. Unlike FileStore, which writes *all* data to
its journal device, BlueStore only journals metadata and (in some
cases) small writes, reducing the size and throughput requirements
for its journal. As with FileStore, the journal can be colocated
on the same device as other data or allocated on a smaller,
high-performance device (e.g., an SSD or NVMe device). BlueStore
journals are only 512 MB by default.
The BlueStore on-disk format is expected to continue to evolve. However, we
will provide support in the OSD to migrate to the new format on upgrade.
.. note: BlueStore is still marked "experimental" in Kraken. We
recommend its use for proof-of-concept and test environments, or
other cases where data loss can be tolerated. Although it is
stable in our testing environment, the code is new and bugs are
inevitable. We hope that with user feedback from Kraken
deployments we will have sufficient confidence to mark it stable
(and the default) in the next major release (Luminous).
In order to enable BlueStore, add the following to ceph.conf::
enable experimental unrecoverable data corrupting features = bluestore
To create a BlueStore OSD, pass the --bluestore option to ceph-disk or
ceph-deploy during OSD creation.
Upgrade notes
-------------
* The OSDs now avoid starting new scrubs while recovery is in progress. To
revert to the old behavior (and do not let recovery activity affect the
scrub scheduling) you can set the following option::
osd scrub during recovery = true
* The list of monitor hosts/addresses for building the monmap can now be
obtained from DNS SRV records. The service name used in when querying the DNS
is defined in the "mon_dns_srv_name" config option, which defaults to
"ceph-mon".
* The 'osd class load list' config option is a list of object class names that
the OSD is permitted to load (or '*' for all classes). By default it
contains all existing in-tree classes for backwards compatibility.
* The 'osd class default list' config option is a list of object class
names (or '*' for all classes) that clients may invoke having only
the '*', 'x', 'class-read', or 'class-write' capabilities. By
default it contains all existing in-tree classes for backwards
compatibility. Invoking classes not listed in 'osd class default
list' requires a capability naming the class (e.g. 'allow class
foo').
* The 'rgw rest getusage op compat' config option allows you to dump
(or not dump) the description of user stats in the S3 GetUsage
API. This option defaults to false. If the value is true, the
reponse data for GetUsage looks like::
"stats": {
"TotalBytes": 516,
"TotalBytesRounded": 1024,
"TotalEntries": 1
}
If the value is false, the reponse for GetUsage looks as it did before::
{
516,
1024,
1
}
* The 'osd out ...' and 'osd in ...' commands now preserve the OSD
weight. That is, after marking an OSD out and then in, the weight
will be the same as before (instead of being reset to 1.0).
Previously the mons would only preserve the weight if the mon
automatically marked and OSD out and then in, but not when an admin
did so explicitly.
* The 'ceph osd perf' command will display 'commit_latency(ms)' and
'apply_latency(ms)'. Previously, the names of these two columns are
'fs_commit_latency(ms)' and 'fs_apply_latency(ms)'. We remove the
prefix 'fs_', because they are not filestore specific.
* Monitors will no longer allow pools to be removed by default. The
setting mon_allow_pool_delete has to be set to true (defaults to
false) before they allow pools to be removed. This is a additional
safeguard against pools being removed by accident.
* If you have manually specified the monitor user rocksdb via the
``mon keyvaluedb = rocksdb`` option, you will need to manually add a
file to the mon data directory to preserve this option::
echo rocksdb > /var/lib/ceph/mon/ceph-`hostname`/kv_backend
New monitors will now use rocksdb by default, but if that file is
not present, existing monitors will use leveldb. The ``mon
keyvaluedb`` option now only affects the backend chosen when a
monitor is created.
* The 'osd crush initial weight' option allows you to specify a CRUSH
weight for a newly added OSD. Previously a value of 0 (the default)
meant that we should use the size of the OSD's store to weight the
new OSD. Now, a value of 0 means it should have a weight of 0, and
a negative value (the new default) means we should automatically
weight the OSD based on its size. If your configuration file
explicitly specifies a value of 0 for this option you will need to
change it to a negative value (e.g., -1) to preserve the current
behavior.
* The `osd crush location` config option is no longer supported. Please
update your ceph.conf to use the `crush location` option instead.
* The static libraries are no longer included by the debian
development packages (lib*-dev) as it is not required per debian
packaging policy. The shared (.so) versions are packaged as before.
* The libtool pseudo-libraries (.la files) are no longer included by
the debian development packages (lib*-dev) as they are not required
per https://wiki.debian.org/ReleaseGoals/LAFileRemoval and
https://www.debian.org/doc/manuals/maint-guide/advanced.en.html.
* The jerasure and shec plugins can now detect SIMD instruction at
runtime and no longer need to be explicitly configured for different
processors. The following plugins are now deprecated:
jerasure_generic, jerasure_sse3, jerasure_sse4, jerasure_neon,
shec_generic, shec_sse3, shec_sse4, and shec_neon. If you use any of
these plugins directly you will see a warning in the mon log file.
Please switch to using just 'jerasure' or 'shec'.
* The librados omap get_keys and get_vals operations include a start key and a
limit on the number of keys to return. The OSD now imposes a configurable
limit on the number of keys and number of total bytes it will respond with,
which means that a librados user might get fewer keys than they asked for.
This is necessary to prevent careless users from requesting an unreasonable
amount of data from the cluster in a single operation. The new limits are
configured with `osd_max_omap_entries_per_request`, defaulting to 131,072, and
'osd_max_omap_bytes_per_request', defaulting to 4MB.
* Calculation of recovery priorities has been updated.
This could lead to unintuitive recovery prioritization
during cluster upgrade. In case of such recovery, OSDs
in old version would operate on different priority ranges
than new ones. Once upgraded, cluster will operate on
consistent values.

v10.2.6 Jewel
=============
This point release fixes several important bugs in RBD mirroring, RGW multi-site, CephFS, and RADOS.
We recommend that all v10.2.x users upgrade.
For more detailed information, see :download:`the complete changelog <changelog/v10.2.6.txt>`.
OSDs No Longer Send ENXIO by Default
------------------------------------
In previous versions, if a client sent an op to the wrong OSD, the OSD
would reply with ENXIO. The rationale here is that the client or OSD is
clearly buggy and we want to surface the error as clearly as possible.
We now only send the ENXIO reply if the osd_enxio_on_misdirected_op option
is enabled (it's off by default). This means that a VM using librbd that
previously would have gotten an EIO and gone read-only will now see a
blocked/hung IO instead.

v10.2.4 Jewel
=============
This point release fixes several important bugs in RBD mirroring, RGW multi-site, CephFS, and RADOS.
We recommend that all v10.2.x users upgrade. Also note the following when upgrading from hammer
Upgrading from hammer
---------------------
When the last hammer OSD in a cluster containing jewel MONs is
upgraded to jewel, as of 10.2.4 the jewel MONs will issue this
warning: "all OSDs are running jewel or later but the
'require_jewel_osds' osdmap flag is not set" and change the
cluster health status to HEALTH_WARN.
This is a signal for the admin to do "ceph osd set require_jewel_osds" - by
doing this, the upgrade path is complete and no more pre-Jewel OSDs may be added
to the cluster.

v10.2.0 Jewel
=============
This major release of Ceph is the foundation for the next
long-term stable release series. There have been many major changes since
the Infernalis (9.2.x) and Hammer (0.94.x) releases, and the upgrade
process is non-trivial. Please read these release notes carefully.
Major Changes from Infernalis
-----------------------------
- *CephFS*:
* This is the first release in which CephFS is declared stable!
Several features are disabled by default, including snapshots and
multiple active MDS servers.
* The repair and disaster recovery tools are now feature-complete.
* A new cephfs-volume-manager module is included that provides a
high-level interface for creating "shares" for OpenStack Manila
and similar projects.
* There is now experimental support for multiple CephFS file systems
within a single cluster.
- *RGW*:
* The multisite feature has been almost completely rearchitected and
rewritten to support any number of clusters/sites, bidirectional
fail-over, and active/active configurations.
* You can now access radosgw buckets via NFS (experimental).
* The AWS4 authentication protocol is now supported.
* There is now support for S3 request payer buckets.
* The new multitenancy infrastructure improves compatibility with
Swift, which provides a separate container namespace for each
user/tenant.
* The OpenStack Keystone v3 API is now supported. There are a range
of other small Swift API features and compatibility improvements
as well, including bulk delete and SLO (static large objects).
- *RBD*:
* There is new support for mirroring (asynchronous replication) of
RBD images across clusters. This is implemented as a per-RBD
image journal that can be streamed across a WAN to another site,
and a new rbd-mirror daemon that performs the cross-cluster
replication.
* The exclusive-lock, object-map, fast-diff, and journaling features
can be enabled or disabled dynamically. The deep-flatten features
can be disabled dynamically but not re-enabled.
* The RBD CLI has been rewritten to provide command-specific help
and full bash completion support.
* RBD snapshots can now be renamed.
- *RADOS*:
* BlueStore, a new OSD backend, is included as an experimental
feature. The plan is for it to become the default backend in the
K or L release.
* The OSD now persists scrub results and provides a librados API to
query results in detail.
* We have revised our documentation to recommend *against* using
ext4 as the underlying filesystem for Ceph OSD daemons due to
problems supporting our long object name handling.
Major Changes from Hammer
-------------------------
- *General*:
* Ceph daemons are now managed via systemd (with the exception of
Ubuntu Trusty, which still uses upstart).
* Ceph daemons run as 'ceph' user instead of 'root'.
* On Red Hat distros, there is also an SELinux policy.
- *RADOS*:
* The RADOS cache tier can now proxy write operations to the base
tier, allowing writes to be handled without forcing migration of
an object into the cache.
* The SHEC erasure coding support is no longer flagged as
experimental. SHEC trades some additional storage space for faster
repair.
* There is now a unified queue (and thus prioritization) of client
IO, recovery, scrubbing, and snapshot trimming.
* There have been many improvements to low-level repair tooling
(ceph-objectstore-tool).
* The internal ObjectStore API has been significantly cleaned up in order
to faciliate new storage backends like BlueStore.
- *RGW*:
* The Swift API now supports object expiration.
* There are many Swift API compatibility improvements.
- *RBD*:
* The ``rbd du`` command shows actual usage (quickly, when
object-map is enabled).
* The object-map feature has seen many stability improvements.
* The object-map and exclusive-lock features can be enabled or disabled
dynamically.
* You can now store user metadata and set persistent librbd options
associated with individual images.
* The new deep-flatten features allow flattening of a clone and all
of its snapshots. (Previously snapshots could not be flattened.)
* The export-diff command is now faster (it uses aio). There is also
a new fast-diff feature.
* The --size argument can be specified with a suffix for units
(e.g., ``--size 64G``).
* There is a new ``rbd status`` command that, for now, shows who has
the image open/mapped.
- *CephFS*:
* You can now rename snapshots.
* There have been ongoing improvements around administration, diagnostics,
and the check and repair tools.
* The caching and revocation of client cache state due to unused
inodes has been dramatically improved.
* The ceph-fuse client behaves better on 32-bit hosts.
Distro compatibility
--------------------
Starting with Infernalis, we have dropped support for many older
distributions so that we can move to a newer compiler toolchain (e.g.,
C++11). Although it is still possible to build Ceph on older
distributions by installing backported development tools, we are not
building and publishing release packages for ceph.com.
We now build packages for the following distributions and architectures:
- x86_64:
* CentOS 7.x. We have dropped support for CentOS 6 (and other RHEL 6
derivatives, like Scientific Linux 6).
* Debian Jessie 8.x. Debian Wheezy 7.x's g++ has incomplete support
for C++11 (and no systemd).
* Ubuntu Xenial 16.04 and Trusty 14.04. Ubuntu Precise 12.04 is no
longer supported.
* Fedora 22 or later.
- aarch64 / arm64:
* Ubuntu Xenial 16.04.
Upgrading from Infernalis or Hammer
-----------------------------------
* We now recommend against using ``ext4`` as the underlying file
system for Ceph OSDs, especially when RGW or other users of long
RADOS object names are used. For more information about why, please
see `Filesystem Recommendations`_.
If you have an existing cluster that uses ext4 for the OSDs but uses only
RBD and/or CephFS, then the ext4 limitations will not affect you. Before
upgrading, be sure add the following to ``ceph.conf`` to allow the OSDs to
start::
osd max object name len = 256
osd max object namespace len = 64
Keep in mind that if you set these lower object name limits and
later decide to use RGW on this cluster, it will have problems
storing S3/Swift objects with long names. This startup check can also be
disabled via the below option, although this is not recommended::
osd check max object name len on startup = false
.. _Filesystem Recommendations: ../configuration/filesystem-recommendations
* There are no major compatibility changes since Infernalis. Simply
upgrading the daemons on each host and restarting all daemons is
sufficient.
* The rbd CLI no longer accepts the deprecated '--image-features' option
during create, import, and clone operations. The '--image-feature'
option should be used instead.
* The rbd legacy image format (version 1) is deprecated with the Jewel release.
Attempting to create a new version 1 RBD image will result in a warning.
Future releases of Ceph will remove support for version 1 RBD images.
* The 'send_pg_creates' and 'map_pg_creates' mon CLI commands are
obsolete and no longer supported.
* A new configure option 'mon_election_timeout' is added to specifically
limit max waiting time of monitor election process, which was previously
restricted by 'mon_lease'.
* CephFS filesystems created using versions older than Firefly (0.80) must
use the new 'cephfs-data-scan tmap_upgrade' command after upgrading to
Jewel. See 'Upgrading' in the CephFS documentation for more information.
* The 'ceph mds setmap' command has been removed.
* The default RBD image features for new images have been updated to
enable the following: exclusive lock, object map, fast-diff, and
deep-flatten. These features are not currently supported by the RBD
kernel driver nor older RBD clients. They can be disabled on a per-image
basis via the RBD CLI, or the default features can be updated to the
pre-Jewel setting by adding the following to the client section of the Ceph
configuration file::
rbd default features = 1
* The rbd legacy image format (version 1) is deprecated with the Jewel
release.
* After upgrading, users should set the 'sortbitwise' flag to enable the new
internal object sort order::
ceph osd set sortbitwise
This flag is important for the new object enumeration API and for
new backends like BlueStore.
* The rbd CLI no longer permits creating images and snapshots with potentially
ambiguous names (e.g. the '/' and '@' characters are disallowed). The
validation can be temporarily disabled by adding "--rbd-validate-names=false"
to the rbd CLI when creating an image or snapshot. It can also be disabled
by adding the following to the client section of the Ceph configuration file::
rbd validate names = false
Upgrading from Hammer
---------------------
* All cluster nodes must first upgrade to Hammer v0.94.4 or a later
v0.94.z release; only then is it possible to upgrade to Jewel
10.2.z.
* For all distributions that support systemd (CentOS 7, Fedora, Debian
Jessie 8.x, OpenSUSE), ceph daemons are now managed using native systemd
files instead of the legacy sysvinit scripts. For example,::
systemctl start ceph.target # start all daemons
systemctl status ceph-osd@12 # check status of osd.12
The main notable distro that is *not* yet using systemd is Ubuntu trusty
14.04. (The next Ubuntu LTS, 16.04, will use systemd instead of upstart.)
* Ceph daemons now run as user and group ``ceph`` by default. The
ceph user has a static UID assigned by Fedora and Debian (also used by
derivative distributions like RHEL/CentOS and Ubuntu). On SUSE the same
UID/GID as in Fedora and Debian will be used, *provided it is not already
assigned*. In the unlikely event the preferred UID or GID is assigned to a
different user/group, ceph will get a dynamically assigned UID/GID.
If your systems already have a ceph user, upgrading the package will cause
problems. We suggest you first remove or rename the existing 'ceph' user
and 'ceph' group before upgrading.
When upgrading, administrators have two options:
#. Add the following line to ``ceph.conf`` on all hosts::
setuser match path = /var/lib/ceph/$type/$cluster-$id
This will make the Ceph daemons run as root (i.e., not drop
privileges and switch to user ceph) if the daemon's data
directory is still owned by root. Newly deployed daemons will
be created with data owned by user ceph and will run with
reduced privileges, but upgraded daemons will continue to run as
root.
#. Fix the data ownership during the upgrade. This is the
preferred option, but it is more work and can be very time
consuming. The process for each host is to:
#. Upgrade the ceph package. This creates the ceph user and group. For
example::
ceph-deploy install --stable jewel HOST
#. Stop the daemon(s).::
service ceph stop # fedora, centos, rhel, debian
stop ceph-all # ubuntu
#. Fix the ownership::
chown -R ceph:ceph /var/lib/ceph
chown -R ceph:ceph /var/log/ceph
#. Restart the daemon(s).::
start ceph-all # ubuntu
systemctl start ceph.target # debian, centos, fedora, rhel
Alternatively, the same process can be done with a single daemon
type, for example by stopping only monitors and chowning only
``/var/lib/ceph/mon``.
* The on-disk format for the experimental KeyValueStore OSD backend has
changed. You will need to remove any OSDs using that backend before you
upgrade any test clusters that use it.
* When a pool quota is reached, librados operations now block indefinitely,
the same way they do when the cluster fills up. (Previously they would return
-ENOSPC.) By default, a full cluster or pool will now block. If your
librados application can handle ENOSPC or EDQUOT errors gracefully, you can
get error returns instead by using the new librados OPERATION_FULL_TRY flag.
* The return code for librbd's rbd_aio_read and Image::aio_read API methods no
longer returns the number of bytes read upon success. Instead, it returns 0
upon success and a negative value upon failure.
* 'ceph scrub', 'ceph compact' and 'ceph sync force' are now DEPRECATED. Users
should instead use 'ceph mon scrub', 'ceph mon compact' and
'ceph mon sync force'.
* 'ceph mon_metadata' should now be used as 'ceph mon metadata'. There is no
need to deprecate this command (same major release since it was first
introduced).
* The `--dump-json` option of "osdmaptool" is replaced by `--dump json`.
* The commands of "pg ls-by-{pool,primary,osd}" and "pg ls" now take "recovering"
instead of "recovery", to include the recovering pgs in the listed pgs.
Upgrading from Firefly
----------------------
Upgrading directly from Firefly v0.80.z is not recommended. It is
possible to do a direct upgrade, but not without downtime, as all OSDs
must be stopped, upgraded, and then restarted. We recommend that
clusters be first upgraded to Hammer v0.94.6 or a later v0.94.z
release; only then is it possible to upgrade to Jewel 10.2.z for an
online upgrade (see below).
To do an offline upgrade directly from Firefly, all Firefly OSDs must
be stopped and marked down before any Jewel OSDs will be allowed
to start up. This fencing is enforced by the Jewel monitor, so
you should use an upgrade procedure like:
#. Upgrade Ceph on monitor hosts
#. Restart all ceph-mon daemons
#. Set noout::
ceph osd set noout
#. Upgrade Ceph on all OSD hosts
#. Stop all ceph-osd daemons
#. Mark all OSDs down with something like::
ceph osd down `seq 0 1000`
#. Start all ceph-osd daemons
#. Let the cluster settle and then unset noout::
ceph osd unset noout
#. Upgrade and restart any remaining daemons (ceph-mds, radosgw)

v10.1.1 Jewel (release candidate)
=================================
This is the first release build that includes arm64/aarch64 packages
for Ubuntu Xenial 16.04.
Know issues with this release candidate
---------------------------------------
There are a few known issues to watch out for:

v10.1.0 Jewel (release candidate)
=================================
There are a few known issues with this release candidate; see below.
Known Issues with v10.1.0
-------------------------
* While running a mixed version cluster of jewel and infernalis or
hammer monitors, any MDSMap updates will cause the pre-jewel
monitors to crash. Workaround is to simply upgrde all monitors.
There is a fix but it is still being tested.
* Some of the rbd-mirror functionality for switching between active
and replica images is not yet merged.

v10.0.3
=======
This is the fourth development release for Jewel. Several big pieces
have been added this release, including BlueStore (a new backend for
OSD to replace FileStore), many ceph-disk fixes, a new CRUSH tunable
that improves mapping stability, a new librados object enumeration API,
and a whole slew of OSD and RADOS optimizations.
Note that, due to general developer busyness, we aren't building official
release packages for this dev release. You can fetch autobuilt gitbuilder
packages from the usual location (gitbuilder.ceph.com).

v10.0.2
=======
This development release includes a raft of changes and improvements
for Jewel. Key additions include CephFS scrub/repair improvements, an
AIX and Solaris port of librados, many librbd journaling additions and
fixes, extended per-pool options, and NBD driver for RBD (rbd-nbd)
that allows librbd to present a kernel-level block device on Linux,
multitenancy support for RGW, RGW bucket lifecycle support, RGW
support for Swift static large objects (SLO), and RGW support for
Swift bulk delete.
There are also lots of smaller optimizations and performance fixes
going in all over the tree, particular in the OSD and common code.

v10.0.1
=======
This is the second development release for the Jewel cycle.
Highlights include some KeyValueDB interface optimizations, initial
journaling support in librbd, MDS scrubbing progress, and a bunch of
OSD optimizations and improvements (removal of an unnecessary CRUSH
calculation in the IO path, sharding for FileStore completions,
improved temperature calculation for cache tiering, fixed
randomization of scrub times, and various optimizations).

v9.2.1 Infernalis
=================
This Infernalis point release fixes several packagins and init script
issues, enables the librbd objectmap feature by default, a few librbd
bugs, and a range of miscellaneous bug fixes across the system.
We recommend that all infernalis v9.2.0 users upgrade.
For more detailed information, see :download:`the complete changelog <changelog/v9.2.1.txt>`.
Upgrading
---------
* Some symbols wrongly exposed by the C++ interface for librados in
v9.1.0 and v9.2.0 were removed. If you compiled your own
application against librados shipped with these releases, it is very
likely referencing these removed symbols. So you will need to
recompile it.

v9.2.0 Infernalis
=================
This major release will be the foundation for the next stable series.
There have been some major changes since v0.94.x Hammer, and the
upgrade process is non-trivial. Please read these release notes carefully.
Major Changes from Hammer
-------------------------
- *General*:
* Ceph daemons are now managed via systemd (with the exception of
Ubuntu Trusty, which still uses upstart).
* Ceph daemons run as 'ceph' user instead root.
* On Red Hat distros, there is also an SELinux policy.
- *RADOS*:
* The RADOS cache tier can now proxy write operations to the base
tier, allowing writes to be handled without forcing migration of
an object into the cache.
* The SHEC erasure coding support is no longer flagged as
experimental. SHEC trades some additional storage space for faster
repair.
* There is now a unified queue (and thus prioritization) of client
IO, recovery, scrubbing, and snapshot trimming.
* There have been many improvements to low-level repair tooling
(ceph-objectstore-tool).
* The internal ObjectStore API has been significantly cleaned up in order
to faciliate new storage backends like NewStore.
- *RGW*:
* The Swift API now supports object expiration.
* There are many Swift API compatibility improvements.
- *RBD*:
* The ``rbd du`` command shows actual usage (quickly, when
object-map is enabled).
* The object-map feature has seen many stability improvements.
* Object-map and exclusive-lock features can be enabled or disabled
dynamically.
* You can now store user metadata and set persistent librbd options
associated with individual images.
* The new deep-flatten features allows flattening of a clone and all
of its snapshots. (Previously snapshots could not be flattened.)
* The export-diff command command is now faster (it uses aio). There is also
a new fast-diff feature.
* The --size argument can be specified with a suffix for units
(e.g., ``--size 64G``).
* There is a new ``rbd status`` command that, for now, shows who has
the image open/mapped.
- *CephFS*:
* You can now rename snapshots.
* There have been ongoing improvements around administration, diagnostics,
and the check and repair tools.
* The caching and revocation of client cache state due to unused
inodes has been dramatically improved.
* The ceph-fuse client behaves better on 32-bit hosts.
Distro compatibility
--------------------
We have decided to drop support for many older distributions so that we can
move to a newer compiler toolchain (e.g., C++11). Although it is still possible
to build Ceph on older distributions by installing backported development tools,
we are not building and publishing release packages for ceph.com.
We now build packages for:
* CentOS 7 or later. We have dropped support for CentOS 6 (and other
RHEL 6 derivatives, like Scientific Linux 6).
* Debian Jessie 8.x or later. Debian Wheezy 7.x's g++ has incomplete
support for C++11 (and no systemd).
* Ubuntu Trusty 14.04 or later. Ubuntu Precise 12.04 is no longer
supported.
* Fedora 22 or later.
Upgrading from Firefly
----------------------
Upgrading directly from Firefly v0.80.z is not recommended. It is
possible to do a direct upgrade, but not without downtime. We
recommend that clusters are first upgraded to Hammer v0.94.4 or a
later v0.94.z release; only then is it possible to upgrade to
Infernalis 9.2.z for an online upgrade (see below).
To do an offline upgrade directly from Firefly, all Firefly OSDs must
be stopped and marked down before any Infernalis OSDs will be allowed
to start up. This fencing is enforced by the Infernalis monitor, so
use an upgrade procedure like:
#. Upgrade Ceph on monitor hosts
#. Restart all ceph-mon daemons
#. Upgrade Ceph on all OSD hosts
#. Stop all ceph-osd daemons
#. Mark all OSDs down with something like::
ceph osd down `seq 0 1000`
#. Start all ceph-osd daemons
#. Upgrade and restart remaining daemons (ceph-mds, radosgw)
Upgrading from Hammer
---------------------
* All cluster nodes must first upgrade to Hammer v0.94.4 or a later v0.94.z release; only
then is it possible to upgrade to Infernalis 9.2.z.
* For all distributions that support systemd (CentOS 7, Fedora, Debian
Jessie 8.x, OpenSUSE), ceph daemons are now managed using native systemd
files instead of the legacy sysvinit scripts. For example,::
systemctl start ceph.target # start all daemons
systemctl status ceph-osd@12 # check status of osd.12
The main notable distro that is *not* yet using systemd is Ubuntu trusty
14.04. (The next Ubuntu LTS, 16.04, will use systemd instead of upstart.)
* Ceph daemons now run as user and group ``ceph`` by default. The
ceph user has a static UID assigned by Fedora and Debian (also used
by derivative distributions like RHEL/CentOS and Ubuntu). On SUSE
the ceph user will currently get a dynamically assigned UID when the
user is created.
If your systems already have a ceph user, upgrading the package will cause
problems. We suggest you first remove or rename the existing 'ceph' user
and 'ceph' group before upgrading.
When upgrading, administrators have two options:
#. Add the following line to ``ceph.conf`` on all hosts::
setuser match path = /var/lib/ceph/$type/$cluster-$id
This will make the Ceph daemons run as root (i.e., not drop
privileges and switch to user ceph) if the daemon's data
directory is still owned by root. Newly deployed daemons will
be created with data owned by user ceph and will run with
reduced privileges, but upgraded daemons will continue to run as
root.
#. Fix the data ownership during the upgrade. This is the
preferred option, but it is more work and can be very time
consuming. The process for each host is to:
#. Upgrade the ceph package. This creates the ceph user and group. For
example::
ceph-deploy install --stable infernalis HOST
#. Stop the daemon(s).::
service ceph stop # fedora, centos, rhel, debian
stop ceph-all # ubuntu
#. Fix the ownership::
chown -R ceph:ceph /var/lib/ceph
chown -R ceph:ceph /var/log/ceph
#. Restart the daemon(s).::
start ceph-all # ubuntu
systemctl start ceph.target # debian, centos, fedora, rhel
Alternatively, the same process can be done with a single daemon
type, for example by stopping only monitors and chowning only
``/var/lib/ceph/mon``.
* The on-disk format for the experimental KeyValueStore OSD backend has
changed. You will need to remove any OSDs using that backend before you
upgrade any test clusters that use it.
* When a pool quota is reached, librados operations now block indefinitely,
the same way they do when the cluster fills up. (Previously they would return
-ENOSPC). By default, a full cluster or pool will now block. If your
librados application can handle ENOSPC or EDQUOT errors gracefully, you can
get error returns instead by using the new librados OPERATION_FULL_TRY flag.
* The return code for librbd's rbd_aio_read and Image::aio_read API methods no
longer returns the number of bytes read upon success. Instead, it returns 0
upon success and a negative value upon failure.
* 'ceph scrub', 'ceph compact' and 'ceph sync force are now DEPRECATED. Users
should instead use 'ceph mon scrub', 'ceph mon compact' and
'ceph mon sync force'.
* 'ceph mon_metadata' should now be used as 'ceph mon metadata'. There is no
need to deprecate this command (same major release since it was first
introduced).
* The `--dump-json` option of "osdmaptool" is replaced by `--dump json`.
* The commands of "pg ls-by-{pool,primary,osd}" and "pg ls" now take "recovering"
instead of "recovery", to include the recovering pgs in the listed pgs.

v9.1.0 Infernalis release candidate
===================================
This is the first Infernalis release candidate. There have been some
major changes since Hammer, and the upgrade process is non-trivial.
Please read carefully.
Getting the release candidate
-----------------------------
The v9.1.0 packages are pushed to the development release repositories::
http://download.ceph.com/rpm-testing
http://download.ceph.com/debian-testing
For for info, see::
http://docs.ceph.com/docs/master/install/get-packages/
Or install with ceph-deploy via::
ceph-deploy install --testing HOST
Known issues
------------
* librbd and librados ABI compatibility is broken. Be careful
installing this RC on client machines (e.g., those running qemu).
It will be fixed in the final v9.2.0 release.
Major Changes from Hammer
-------------------------
- *General*:
* Ceph daemons are now managed via systemd (with the exception of
Ubuntu Trusty, which still uses upstart).
* Ceph daemons run as 'ceph' user instead of root.
* On Red Hat distros, there is also an SELinux policy.
- *RADOS*:
* The RADOS cache tier can now proxy write operations to the base
tier, allowing writes to be handled without forcing migration of
an object into the cache.
* The SHEC erasure coding support is no longer flagged as
experimental. SHEC trades some additional storage space for faster
repair.
* There is now a unified queue (and thus prioritization) of client
IO, scrubbing, and snapshot trimming.
* There have been many improvements to low-level repair tooling
(ceph-objectstore-tool).
* The internal ObjectStore API has been significantly cleaned up in order
to faciliate new storage backends like NewStore.
- *RGW*:
* The Swift API now supports object expiration.
* There are many Swift API compatibility improvements.
- *RBD*:
* The ``rbd du`` command shows actual usage (quickly, when
object-map is enabled).
* The object-map feature has seen many stability improvements.
* Object-map and exclusive-lock features can be enabled or disabled
dynamically.
* You can now store user metadata and set persistent librbd options
associated with individual images.
* The new deep-flatten features allows flattening of a clone and all
of its snapshots. (Previously snapshots could not be flattened.)
* The export-diff command command is now faster (it uses aio). There is also
a new fast-diff feature.
* The --size argument can be specified with a suffix for units
(e.g., ``--size 64G``).
* There is a new ``rbd status`` command that, for now, shows who has
the image open/mapped.
- *CephFS*:
* You can now rename snapshots.
* There have been ongoing improvements around administration, diagnostics,
and the check and repair tools.
* The caching and revocation of client cache state due to unused
inodes has been dramatically improved.
* The ceph-fuse client behaves better on 32-bit hosts.
Distro compatibility
--------------------
We have decided to drop support for many older distributions so that we can
move to a newer compiler toolchain (e.g., C++11). Although it is still possible
to build Ceph on older distributions by installing backported development tools,
we are not building and publishing release packages for them on ceph.com.
In particular,
* CentOS 7 or later; we have dropped support for CentOS 6 (and other
RHEL 6 derivatives, like Scientific Linux 6).
* Debian Jessie 8.x or later; Debian Wheezy 7.x's g++ has incomplete
support for C++11 (and no systemd).
* Ubuntu Trusty 14.04 or later; Ubuntu Precise 12.04 is no longer
supported.
* Fedora 22 or later.
Upgrading from Firefly
----------------------
Upgrading directly from Firefly v0.80.z is not possible. All clusters
must first upgrade to Hammer v0.94.4 or a later v0.94.z release; only
then is it possible to do online upgrade to Infernalis 9.2.z.
User can upgrade to latest hammer v0.94.z
from gitbuilder with(also refer the hammer release notes for more details)::
ceph-deploy install --release hammer HOST
Upgrading from Hammer
---------------------
* All cluster nodes must first upgrade to Hammer v0.94.4 or a later v0.94.z release; only
then is it possible to do online upgrade to Infernalis 9.2.z.
* For all distributions that support systemd (CentOS 7, Fedora, Debian
Jessie 8.x, OpenSUSE), ceph daemons are now managed using native systemd
files instead of the legacy sysvinit scripts. For example,::
systemctl start ceph.target # start all daemons
systemctl status ceph-osd@12 # check status of osd.12
The main notable distro that is *not* yet using systemd is Ubuntu trusty
14.04. (The next Ubuntu LTS, 16.04, will use systemd instead of upstart.)
* Ceph daemons now run as user and group ``ceph`` by default. The
ceph user has a static UID assigned by Fedora and Debian (also used
by derivative distributions like RHEL/CentOS and Ubuntu). On SUSE
the ceph user will currently get a dynamically assigned UID when the
user is created.
If your systems already have a ceph user, the package upgrade
process will usually fail with an error. We suggest you first
remove or rename the existing 'ceph' user and then upgrade.
When upgrading, administrators have two options:
#. Add the following line to ``ceph.conf`` on all hosts::
setuser match path = /var/lib/ceph/$type/$cluster-$id
This will make the Ceph daemons run as root (i.e., not drop
privileges and switch to user ceph) if the daemon's data
directory is still owned by root. Newly deployed daemons will
be created with data owned by user ceph and will run with
reduced privileges, but upgraded daemons will continue to run as
root.
#. Fix the data ownership during the upgrade. This is the preferred option,
but is more work. The process for each host would be to:
#. Upgrade the ceph package. This creates the ceph user and group. For
example::
ceph-deploy install --stable infernalis HOST
#. Stop the daemon(s).::
service ceph stop # fedora, centos, rhel, debian
stop ceph-all # ubuntu
#. Fix the ownership::
chown -R ceph:ceph /var/lib/ceph
chown -R ceph:ceph /var/log/ceph
#. Restart the daemon(s).::
start ceph-all # ubuntu
systemctl start ceph.target # debian, centos, fedora, rhel
* The on-disk format for the experimental KeyValueStore OSD backend has
changed. You will need to remove any OSDs using that backend before you
upgrade any test clusters that use it.
Upgrade notes
-------------
* When a pool quota is reached, librados operations now block indefinitely,
the same way they do when the cluster fills up. (Previously they would return
-ENOSPC). By default, a full cluster or pool will now block. If your
librados application can handle ENOSPC or EDQUOT errors gracefully, you can
get error returns instead by using the new librados OPERATION_FULL_TRY flag.

v9.0.3
======
This is the second to last batch of development work for the
Infernalis cycle. The most intrusive change is an internal (non
user-visible) change to the OSD's ObjectStore interface. Many fixes and
improvements elsewhere across RGW, RBD, and another big pile of CephFS
scrub/repair improvements.
Upgrading
---------
* The return code for librbd's rbd_aio_read and Image::aio_read API methods no
longer returns the number of bytes read upon success. Instead, it returns 0
upon success and a negative value upon failure.
* 'ceph scrub', 'ceph compact' and 'ceph sync force' are now deprecated. Users
should instead use 'ceph mon scrub', 'ceph mon compact' and
'ceph mon sync force'.
* 'ceph mon_metadata' should now be used as 'ceph mon metadata'.
* The `--dump-json` option of "osdmaptool" is replaced by `--dump json`.
* The commands of 'pg ls-by-{pool,primary,osd}' and 'pg ls' now take 'recovering'
instead of 'recovery' to include the recovering pgs in the listed pgs.

v9.0.0
======
This is the first development release for the Infernalis cycle, and
the first Ceph release to sport a version number from the new
numbering scheme. The "9" indicates this is the 9th release cycle--I
(for Infernalis) is the 9th letter. The first "0" indicates this is a
development release ("1" will mean release candidate and "2" will mean
stable release), and the final "0" indicates this is the first such
development release.
A few highlights include:
* a new 'ceph daemonperf' command to watch perfcounter stats in realtime
* reduced MDS memory usage
* many MDS snapshot fixes
* librbd can now store options in the image itself
* many fixes for RGW Swift API support
* OSD performance improvements
* many doc updates and misc bug fixes

v0.94.10 Hammer
===============
This Hammer point release fixes several bugs and adds two new features.
We recommend that all hammer v0.94.x users upgrade.
For more detailed information, see :download:`the complete changelog <changelog/v0.94.10.txt>`.
New Features
------------
ceph-objectstore-tool and ceph-monstore-tool now enable user to
rebuild the monitor database from OSDs. (This feature is especially useful when
all monitors fail to boot due to leveldb corruption.)
In RADOS Gateway, it is now possible to reshard an existing bucket's index
using an off-line tool.
Usage:
$ radosgw-admin bucket reshard --bucket=<bucket_name> --num_shards=<num_shards>
This will create a new linked bucket instance that points to the newly created
index objects. The old bucket instance still exists and currently it's up to
the user to manually remove the old bucket index objects. (Note that bucket
resharding currently requires that all IO (especially writes) to the specific
bucket is quiesced.)

v0.94.7 Hammer
==============
This Hammer point release fixes several minor bugs. It also includes
a backport of an improved 'ceph osd reweight-by-utilization' command
for handling OSDs with higher-than-average utilizations.
We recommend that all hammer v0.94.x users upgrade.
For more detailed information, see :download:`the complete changelog <changelog/v0.94.7.txt>`.

v0.94.6 Hammer
======================
This Hammer point release fixes a range of bugs, most notably a fix
for unbounded growth of the monitor's leveldb store, and a workaround
in the OSD to keep most xattrs small enough to be stored inline in XFS
inodes.
We recommend that all hammer v0.94.x users upgrade.
For more detailed information, see :download:`the complete changelog <changelog/v0.94.6.txt>`.

v0.94.4 Hammer
==============
This Hammer point release fixes several important bugs in Hammer, as well as
fixing interoperability issues that are required before an upgrade to
Infernalis. That is, all users of earlier version of Hammer or any
version of Firefly will first need to upgrade to hammer v0.94.4 or
later before upgrading to Infernalis (or future releases).
All v0.94.x Hammer users are strongly encouraged to upgrade.

v0.94.3 Hammer
==============
This Hammer point release fixes a critical (though rare) data
corruption bug that could be triggered when logs are rotated via
SIGHUP. It also fixes a range of other important bugs in the OSD,
monitor, RGW, RGW, and CephFS.
All v0.94.x Hammer users are strongly encouraged to upgrade.
Upgrading
---------
* The ``pg ls-by-{pool,primary,osd}`` commands and ``pg ls`` now take
the argument ``recovering`` instead of ``recovery`` in order to
include the recovering pgs in the listed pgs.
Notable Changes

v0.94.2 Hammer
==============
This Hammer point release fixes a few critical bugs in RGW that can
prevent objects starting with underscore from behaving properly and
that prevent garbage collection of deleted objects when using the
Civetweb standalone mode.
All v0.94.x Hammer users are strongly encouraged to upgrade, and to
make note of the repair procedure below if RGW is in use.
Upgrading from previous Hammer release
--------------------------------------
Bug #11442 introduced a change that made rgw objects that start with underscore
incompatible with previous versions. The fix to that bug reverts to the
previous behavior. In order to be able to access objects that start with an
underscore and were created in prior Hammer releases, following the upgrade it
is required to run (for each affected bucket)::
$ radosgw-admin bucket check --check-head-obj-locator \
--bucket=<bucket> [--fix]

v0.94.1 Hammer
==============
This bug fix release fixes a few critical issues with CRUSH. The most
important addresses a bug in feature bit enforcement that may prevent
pre-hammer clients from communicating with the cluster during an
upgrade. This only manifests in some cases (for example, when the
'rack' type is in use in the CRUSH map, and possibly other cases), but for
safety we strongly recommend that all users use 0.94.1 instead of 0.94 when
upgrading.
There is also a fix in the new straw2 buckets when OSD weights are 0.
We recommend that all v0.94 users upgrade.
Notable changes
---------------
* crush: fix divide-by-0 in straw2 (#11357 Sage Weil)
* crush: fix has_v4_buckets (#11364 Sage Weil)
* osd: fix negative degraded objects during backfilling (#7737 Guang Yang)
For more detailed information, see :download:`the complete changelog <changelog/v0.94.1.txt>`.
v0.94 Hammer
============
This major release is expected to form the basis of the next long-term
stable series. It is intended to supersede v0.80.x Firefly.
Highlights since Giant include:
* *RADOS Performance*: a range of improvements have been made in the
OSD and client-side librados code that improve the throughput on
flash backends and improve parallelism and scaling on fast machines.
* *Simplified RGW deployment*: the ceph-deploy tool now has a new
'ceph-deploy rgw create HOST' command that quickly deploys a
instance of the S3/Swift gateway using the embedded Civetweb server.
This is vastly simpler than the previous Apache-based deployment.
There are a few rough edges (e.g., around SSL support) but we
encourage users to try `the new method`_.
* *RGW object versioning*: RGW now supports the S3 object versioning
API, which preserves old version of objects instead of overwriting
them.
* *RGW bucket sharding*: RGW can now shard the bucket index for large
buckets across, improving performance for very large buckets.
* *RBD object maps*: RBD now has an object map function that tracks
which parts of the image are allocating, improving performance for
clones and for commands like export and delete.
* *RBD mandatory locking*: RBD has a new mandatory locking framework
(still disabled by default) that adds additional safeguards to
prevent multiple clients from using the same image at the same time.
* *RBD copy-on-read*: RBD now supports copy-on-read for image clones,
improving performance for some workloads.
* *CephFS snapshot improvements*: Many many bugs have been fixed with
CephFS snapshots. Although they are still disabled by default,
stability has improved significantly.
* *CephFS Recovery tools*: We have built some journal recovery and
diagnostic tools. Stability and performance of single-MDS systems is
vastly improved in Giant, and more improvements have been made now
in Hammer. Although we still recommend caution when storing
important data in CephFS, we do encourage testing for non-critical
workloads so that we can better guage the feature, usability,
performance, and stability gaps.
* *CRUSH improvements*: We have added a new straw2 bucket algorithm
that reduces the amount of data migration required when changes are
made to the cluster.
* *Shingled erasure codes (SHEC)*: The OSDs now have experimental
support for shingled erasure codes, which allow a small amount of
additional storage to be traded for improved recovery performance.
* *RADOS cache tiering*: A series of changes have been made in the
cache tiering code that improve performance and reduce latency.
* *RDMA support*: There is now experimental support the RDMA via the
Accelio (libxio) library.
* *New administrator commands*: The 'ceph osd df' command shows
pertinent details on OSD disk utilizations. The 'ceph pg ls ...'
command makes it much simpler to query PG states while diagnosing
cluster issues.
.. _the new method: ../start/quick-ceph-deploy/#add-an-rgw-instance
Other highlights since Firefly include:
* *CephFS*: we have fixed a raft of bugs in CephFS and built some
basic journal recovery and diagnostic tools. Stability and
performance of single-MDS systems is vastly improved in Giant.
Although we do not yet recommend CephFS for production deployments,
we do encourage testing for non-critical workloads so that we can
better guage the feature, usability, performance, and stability
gaps.
* *Local Recovery Codes*: the OSDs now support an erasure-coding scheme
that stores some additional data blocks to reduce the IO required to
recover from single OSD failures.
* *Degraded vs misplaced*: the Ceph health reports from 'ceph -s' and
related commands now make a distinction between data that is
degraded (there are fewer than the desired number of copies) and
data that is misplaced (stored in the wrong location in the
cluster). The distinction is important because the latter does not
compromise data safety.
* *Tiering improvements*: we have made several improvements to the
cache tiering implementation that improve performance. Most
notably, objects are not promoted into the cache tier by a single
read; they must be found to be sufficiently hot before that happens.
* *Monitor performance*: the monitors now perform writes to the local
data store asynchronously, improving overall responsiveness.
* *Recovery tools*: the ceph-objectstore-tool is greatly expanded to
allow manipulation of an individual OSDs data store for debugging
and repair purposes. This is most heavily used by our QA
infrastructure to exercise recovery code.
I would like to take this opportunity to call out the amazing growth
in contributors to Ceph beyond the core development team from Inktank.
Hammer features major new features and improvements from Intel, Fujitsu,
UnitedStack, Yahoo, UbuntuKylin, CohortFS, Mellanox, CERN, Deutsche
Telekom, Mirantis, and SanDisk.
Dedication
----------
This release is dedicated in memoriam to Sandon Van Ness, aka
Houkouonchi, who unexpectedly passed away a few weeks ago. Sandon was
responsible for maintaining the large and complex Sepia lab that
houses the Ceph project's build and test infrastructure. His efforts
have made an important impact on our ability to reliably test Ceph
with a relatively small group of people. He was a valued member of
the team and we will miss him. H is also for Houkouonchi.
Upgrading
---------
* If your existing cluster is running a version older than v0.80.x
Firefly, please first upgrade to the latest Firefly release before
moving on to Giant. We have not tested upgrades directly from
Emperor, Dumpling, or older releases.
We *have* tested:
* Firefly to Hammer
* Giant to Hammer
* Dumpling to Firefly to Hammer
* Please upgrade daemons in the following order:
#. Monitors
#. OSDs
#. MDSs and/or radosgw
Note that the relative ordering of OSDs and monitors should not matter, but
we primarily tested upgrading monitors first.
* The ceph-osd daemons will perform a disk-format upgrade improve the
PG metadata layout and to repair a minor bug in the on-disk format.
It may take a minute or two for this to complete, depending on how
many objects are stored on the node; do not be alarmed if they do
not marked "up" by the cluster immediately after starting.
* If upgrading from v0.93, set
osd enable degraded writes = false
on all osds prior to upgrading. The degraded writes feature has
been reverted due to 11155.
* The LTTNG tracing in librbd and librados is disabled in the release packages
until we find a way to avoid violating distro security policies when linking
libust.
Upgrading from v0.87.x Giant
----------------------------
* librbd and librados include lttng tracepoints on distros with
liblttng 2.4 or later (only Ubuntu Trusty for the ceph.com
packages). When running a daemon that uses these libraries, i.e. an
application that calls fork(2) or clone(2) without exec(3), you must
set LD_PRELOAD=liblttng-ust-fork.so.0 to prevent a crash in the
lttng atexit handler when the process exits. The only ceph tool that
requires this is rbd-fuse.
* If rgw_socket_path is defined and rgw_frontends defines a
socket_port and socket_host, we now allow the rgw_frontends settings
to take precedence. This change should only affect users who have
made non-standard changes to their radosgw configuration.
* If you are upgrading specifically from v0.92, you must stop all OSD
daemons and flush their journals (``ceph-osd -i NNN
--flush-journal``) before upgrading. There was a transaction
encoding bug in v0.92 that broke compatibility. Upgrading from v0.93,
v0.91, or anything earlier is safe.
* The experimental 'keyvaluestore-dev' OSD backend has been renamed
'keyvaluestore' (for simplicity) and marked as experimental. To
enable this untested feature and acknowledge that you understand
that it is untested and may destroy data, you need to add the
following to your ceph.conf::
enable experimental unrecoverable data corrupting featuers = keyvaluestore
* The following librados C API function calls take a 'flags' argument whose value
is now correctly interpreted:
rados_write_op_operate()
rados_aio_write_op_operate()
rados_read_op_operate()
rados_aio_read_op_operate()
The flags were not correctly being translated from the librados constants to the
internal values. Now they are. Any code that is passing flags to these methods
should be audited to ensure that they are using the correct LIBRADOS_OP_FLAG_*
constants.
* The 'rados' CLI 'copy' and 'cppool' commands now use the copy-from operation,
which means the latest CLI cannot run these commands against pre-firefly OSDs.
* The librados watch/notify API now includes a watch_flush() operation to flush
the async queue of notify operations. This should be called by any watch/notify
user prior to rados_shutdown().
* The 'category' field for objects has been removed. This was originally added
to track PG stat summations over different categories of objects for use by
radosgw. It is no longer has any known users and is prone to abuse because it
can lead to a pg_stat_t structure that is unbounded. The librados API calls
that accept this field now ignore it, and the OSD no longers tracks the
per-category summations.
* The output for 'rados df' has changed. The 'category' level has been
eliminated, so there is now a single stat object per pool. The structure of
the JSON output is different, and the plaintext output has one less column.
* The 'rados create <objectname> [category]' optional category argument is no
longer supported or recognized.
* rados.py's Rados class no longer has a __del__ method; it was causing
problems on interpreter shutdown and use of threads. If your code has
Rados objects with limited lifetimes and you're concerned about locked
resources, call Rados.shutdown() explicitly.
* There is a new version of the librados watch/notify API with vastly
improved semantics. Any applications using this interface are
encouraged to migrate to the new API. The old API calls are marked
as deprecated and will eventually be removed.
* The librados rados_unwatch() call used to be safe to call on an
invalid handle. The new version has undefined behavior when passed
a bogus value (for example, when rados_watch() returns an error and
handle is not defined).
* The structure of the formatted 'pg stat' command is changed for the
portion that counts states by name to avoid using the '+' character
(which appears in state names) as part of the XML token (it is not
legal).
* Previously, the formatted output of 'ceph pg stat -f ...' was a full
pg dump that included all metadata about all PGs in the system. It
is now a concise summary of high-level PG stats, just like the
unformatted 'ceph pg stat' command.
* All JSON dumps of floating point values were incorrecting surrounding the
value with quotes. These quotes have been removed. Any consumer of structured
JSON output that was consuming the floating point values was previously having
to interpret the quoted string and will most likely need to be fixed to take
the unquoted number.
* New ability to list all objects from all namespaces that can fail or
return incomplete results when not all OSDs have been upgraded.
Features rados --all ls, rados cppool, rados export, rados
cache-flush-evict-all and rados cache-try-flush-evict-all can also
fail or return incomplete results.
* Due to a change in the Linux kernel version 3.18 and the limits of the FUSE
interface, ceph-fuse needs be mounted as root on at least some systems. See
issues #9997, #10277, and #10542 for details.
Upgrading from v0.80x Firefly (additional notes)
------------------------------------------------
* The client-side caching for librbd is now enabled by default (rbd
cache = true). A safety option (rbd cache writethrough until flush
= true) is also enabled so that writeback caching is not used until
the library observes a 'flush' command, indicating that the librbd
users is passing that operation through from the guest VM. This
avoids potential data loss when used with older versions of qemu
that do not support flush.
leveldb_write_buffer_size = 8*1024*1024 = 33554432 // 8MB
leveldb_cache_size = 512*1024*1204 = 536870912 // 512MB
leveldb_block_size = 64*1024 = 65536 // 64KB
leveldb_compression = false
leveldb_log = ""
OSDs will still maintain the following osd-specific defaults:
leveldb_log = ""
* The 'rados getxattr ...' command used to add a gratuitous newline to the attr
value; it now does not.
* The ``*_kb perf`` counters on the monitor have been removed. These are
replaced with a new set of ``*_bytes`` counters (e.g., ``cluster_osd_kb`` is
replaced by ``cluster_osd_bytes``).
* The ``rd_kb`` and ``wr_kb`` fields in the JSON dumps for pool stats (accessed
via the ``ceph df detail -f json-pretty`` and related commands) have been
replaced with corresponding ``*_bytes`` fields. Similarly, the
``total_space``, ``total_used``, and ``total_avail`` fields are replaced with
``total_bytes``, ``total_used_bytes``, and ``total_avail_bytes`` fields.
* The ``rados df --format=json`` output ``read_bytes`` and ``write_bytes``
fields were incorrectly reporting ops; this is now fixed.
* The ``rados df --format=json`` output previously included ``read_kb`` and
``write_kb`` fields; these have been removed. Please use ``read_bytes`` and
``write_bytes`` instead (and divide by 1024 if appropriate).
* The experimental keyvaluestore-dev OSD backend had an on-disk format
change that prevents existing OSD data from being upgraded. This
affects developers and testers only.
* mon-specific and osd-specific leveldb options have been removed.
From this point onward users should use the `leveldb_*` generic
options and add the options in the appropriate sections of their
configuration files. Monitors will still maintain the following
monitor-specific defaults:
leveldb_write_buffer_size = 8*1024*1024 = 33554432 // 8MB
leveldb_cache_size = 512*1024*1204 = 536870912 // 512MB
leveldb_block_size = 64*1024 = 65536 // 64KB
leveldb_compression = false
leveldb_log = ""
OSDs will still maintain the following osd-specific defaults:
leveldb_log = ""
* CephFS support for the legacy anchor table has finally been removed.
Users with file systems created before firefly should ensure that inodes
with multiple hard links are modified *prior* to the upgrade to ensure that
the backtraces are written properly. For example::
sudo find /mnt/cephfs -type f -links +1 -exec touch \{\} \;
* We disallow nonsensical 'tier cache-mode' transitions. From this point
onward, 'writeback' can only transition to 'forward' and 'forward'
can transition to 1) 'writeback' if there are dirty objects, or 2) any if
there are no dirty objects.

v0.93
=====
This is the first release candidate for Hammer, and includes all of
the features that will be present in the final release. We welcome
and encourage any and all testing in non-production clusters to identify
any problems with functionality, stability, or performance before the
final Hammer release.
We suggest some caution in one area: librbd. There is a lot of new
functionality around object maps and locking that is disabled by
default but may still affect stability for existing images. We are
continuing to shake out those bugs so that the final Hammer release
(probably v0.94) will be rock solid.
Major features since Giant include:
* cephfs: journal scavenger repair tool (John Spray)
* crush: new and improved straw2 bucket type (Sage Weil, Christina Anderson, Xiaoxi Chen)
* doc: improved guidance for CephFS early adopters (John Spray)
* librbd: add per-image object map for improved performance (Jason Dillaman)
* librbd: copy-on-read (Min Chen, Li Wang, Yunchuan Wen, Cheng Cheng)
* librados: fadvise-style IO hints (Jianpeng Ma)
* mds: many many snapshot-related fixes (Yan, Zheng)
* mon: new 'ceph osd df' command (Mykola Golub)
* mon: new 'ceph pg ls ...' command (Xinxin Shu)
* osd: improved performance for high-performance backends
* osd: improved recovery behavior (Samuel Just)
* osd: improved cache tier behavior with reads (Zhiqiang Wang)
* rgw: S3-compatible bucket versioning support (Yehuda Sadeh)
* rgw: large bucket index sharding (Guang Yang, Yehuda Sadeh)
* RDMA "xio" messenger support (Matt Benjamin, Vu Pham)
Upgrading
---------
* If you are upgrading from v0.92, you must stop all OSD daemons and flush their
journals (``ceph-osd -i NNN --flush-journal``) before upgrading. There was
a transaction encoding bug in v0.92 that broke compatibility. Upgrading from
v0.91 or anything earlier is safe.
* No special restrictions when upgrading from firefly or giant.

v0.92
=====
This is the second-to-last chunk of new stuff before Hammer. Big items
include additional checksums on OSD objects, proxied reads in the
cache tier, image locking in RBD, optimized OSD Transaction and
replication messages, and a big pile of RGW and MDS bug fixes.
Upgrading
---------
* The experimental 'keyvaluestore-dev' OSD backend has been renamed
'keyvaluestore' (for simplicity) and marked as experimental. To
enable this untested feature and acknowledge that you understand
that it is untested and may destroy data, you need to add the
following to your ceph.conf::
enable experimental unrecoverable data corrupting featuers = keyvaluestore
* The following librados C API function calls take a 'flags' argument whose value
is now correctly interpreted:
rados_write_op_operate()
rados_aio_write_op_operate()
rados_read_op_operate()
rados_aio_read_op_operate()
The flags were not correctly being translated from the librados constants to the
internal values. Now they are. Any code that is passing flags to these methods
should be audited to ensure that they are using the correct LIBRADOS_OP_FLAG_*
constants.
* The 'rados' CLI 'copy' and 'cppool' commands now use the copy-from operation,
which means the latest CLI cannot run these commands against pre-firefly OSDs.
* The librados watch/notify API now includes a watch_flush() operation to flush
the async queue of notify operations. This should be called by any watch/notify
user prior to rados_shutdown().

v0.91
=====
We are quickly approaching the Hammer feature freeze but have a few
more dev releases to go before we get there. The headline items are
subtree-based quota support in CephFS (ceph-fuse/libcephfs client
support only for now), a rewrite of the watch/notify librados API used
by RBD and RGW, OSDMap checksums to ensure that maps are always
consistent inside the cluster, new API calls in librados and librbd
for IO hinting modeled after posix_fadvise, and improved storage of
per-PG state.
We expect two more releases before the Hammer feature freeze (v0.93).
Upgrading
---------
* The 'category' field for objects has been removed. This was originally added
to track PG stat summations over different categories of objects for use by
radosgw. It is no longer has any known users and is prone to abuse because it
can lead to a pg_stat_t structure that is unbounded. The librados API calls
that accept this field now ignore it, and the OSD no longers tracks the
per-category summations.
* The output for 'rados df' has changed. The 'category' level has been
eliminated, so there is now a single stat object per pool. The structure of
the JSON output is different, and the plaintext output has one less column.
* The 'rados create <objectname> [category]' optional category argument is no
longer supported or recognized.
* rados.py's Rados class no longer has a __del__ method; it was causing
problems on interpreter shutdown and use of threads. If your code has
Rados objects with limited lifetimes and you're concerned about locked
resources, call Rados.shutdown() explicitly.
* There is a new version of the librados watch/notify API with vastly
improved semantics. Any applications using this interface are
encouraged to migrate to the new API. The old API calls are marked
as deprecated and will eventually be removed.
* The librados rados_unwatch() call used to be safe to call on an
invalid handle. The new version has undefined behavior when passed
a bogus value (for example, when rados_watch() returns an error and
handle is not defined).
* The structure of the formatted 'pg stat' command is changed for the
portion that counts states by name to avoid using the '+' character
(which appears in state names) as part of the XML token (it is not
legal).

v0.90
=====
This is the last development release before Christmas. There are some
API cleanups for librados and librbd, and lots of bug fixes across the
board for the OSD, MDS, RGW, and CRUSH. The OSD also gets support for
discard (potentially helpful on SSDs, although it is off by default), and there
are several improvements to ceph-disk.
The next two development releases will be getting a slew of new
functionality for hammer. Stay tuned!
Upgrading
---------
* Previously, the formatted output of 'ceph pg stat -f ...' was a full
pg dump that included all metadata about all PGs in the system. It
is now a concise summary of high-level PG stats, just like the
unformatted 'ceph pg stat' command.
* All JSON dumps of floating point values were incorrecting surrounding the
value with quotes. These quotes have been removed. Any consumer of structured
JSON output that was consuming the floating point values was previously having
to interpret the quoted string and will most likely need to be fixed to take
the unquoted number.

v0.89
=====
This is the second development release since Giant. The big items
include the first batch of scrub patchs from Greg for CephFS, a rework
in the librados object listing API to properly handle namespaces, and
a pile of bug fixes for RGW. There are also several smaller issues
fixed up in the performance area with buffer alignment and memory
copies, osd cache tiering agent, and various CephFS fixes.
Upgrading
---------
* New ability to list all objects from all namespaces can fail or
return incomplete results when not all OSDs have been upgraded.
Features rados --all ls, rados cppool, rados export, rados
cache-flush-evict-all and rados cache-try-flush-evict-all can also
fail or return incomplete results.

v0.88
=====
This is the first development release after Giant. The two main
features merged this round are the new AsyncMessenger (an alternative
implementation of the network layer) from Haomai Wang at UnitedStack,
and support for POSIX file locks in ceph-fuse and libcephfs from Yan,
Zheng. There is also a big pile of smaller items that re merged while
we were stabilizing Giant, including a range of smaller performance
and bug fixes and some new tracepoints for LTTNG.

v0.87 Giant
===========
This release will form the basis for the stable release Giant,
v0.87.x. Highlights for Giant include:
* *RADOS Performance*: a range of improvements have been made in the
OSD and client-side librados code that improve the throughput on
flash backends and improve parallelism and scaling on fast machines.
* *CephFS*: we have fixed a raft of bugs in CephFS and built some
basic journal recovery and diagnostic tools. Stability and
performance of single-MDS systems is vastly improved in Giant.
Although we do not yet recommend CephFS for production deployments,
we do encourage testing for non-critical workloads so that we can
better guage the feature, usability, performance, and stability
gaps.
* *Local Recovery Codes*: the OSDs now support an erasure-coding scheme
that stores some additional data blocks to reduce the IO required to
recover from single OSD failures.
* *Degraded vs misplaced*: the Ceph health reports from 'ceph -s' and
related commands now make a distinction between data that is
degraded (there are fewer than the desired number of copies) and
data that is misplaced (stored in the wrong location in the
cluster). The distinction is important because the latter does not
compromise data safety.
* *Tiering improvements*: we have made several improvements to the
cache tiering implementation that improve performance. Most
notably, objects are not promoted into the cache tier by a single
read; they must be found to be sufficiently hot before that happens.
* *Monitor performance*: the monitors now perform writes to the local
data store asynchronously, improving overall responsiveness.
* *Recovery tools*: the ceph_objectstore_tool is greatly expanded to
allow manipulation of an individual OSDs data store for debugging
and repair purposes. This is most heavily used by our QA
infrastructure to exercise recovery code.
Upgrade Sequencing
------------------
* If your existing cluster is running a version older than v0.80.x
Firefly, please first upgrade to the latest Firefly release before
moving on to Giant. We have not tested upgrades directly from
Emperor, Dumpling, or older releases.
We *have* tested:
* Firefly to Giant
* Dumpling to Firefly to Giant
* Please upgrade daemons in the following order:
#. Monitors
#. OSDs
#. MDSs and/or radosgw
Note that the relative ordering of OSDs and monitors should not matter, but
we primarily tested upgrading monitors first.
Upgrading from v0.80x Firefly
-----------------------------
* The client-side caching for librbd is now enabled by default (rbd
cache = true). A safety option (rbd cache writethrough until flush
= true) is also enabled so that writeback caching is not used until
the library observes a 'flush' command, indicating that the librbd
users is passing that operation through from the guest VM. This
avoids potential data loss when used with older versions of qemu
that do not support flush.
leveldb_write_buffer_size = 8*1024*1024 = 33554432 // 8MB
leveldb_cache_size = 512*1024*1204 = 536870912 // 512MB
leveldb_block_size = 64*1024 = 65536 // 64KB
leveldb_compression = false
leveldb_log = ""
OSDs will still maintain the following osd-specific defaults:
leveldb_log = ""
* The 'rados getxattr ...' command used to add a gratuitous newline to the attr
value; it now does not.
* The ``*_kb perf`` counters on the monitor have been removed. These are
replaced with a new set of ``*_bytes`` counters (e.g., ``cluster_osd_kb`` is
replaced by ``cluster_osd_bytes``).
* The ``rd_kb`` and ``wr_kb`` fields in the JSON dumps for pool stats (accessed
via the ``ceph df detail -f json-pretty`` and related commands) have been
replaced with corresponding ``*_bytes`` fields. Similarly, the
``total_space``, ``total_used``, and ``total_avail`` fields are replaced with
``total_bytes``, ``total_used_bytes``, and ``total_avail_bytes`` fields.
* The ``rados df --format=json`` output ``read_bytes`` and ``write_bytes``
fields were incorrectly reporting ops; this is now fixed.
* The ``rados df --format=json`` output previously included ``read_kb`` and
``write_kb`` fields; these have been removed. Please use ``read_bytes`` and
``write_bytes`` instead (and divide by 1024 if appropriate).
* The experimental keyvaluestore-dev OSD backend had an on-disk format
change that prevents existing OSD data from being upgraded. This
affects developers and testers only.
* mon-specific and osd-specific leveldb options have been removed.
From this point onward users should use the `leveldb_*` generic
options and add the options in the appropriate sections of their
configuration files. Monitors will still maintain the following
monitor-specific defaults:
leveldb_write_buffer_size = 8*1024*1024 = 33554432 // 8MB
leveldb_cache_size = 512*1024*1204 = 536870912 // 512MB
leveldb_block_size = 64*1024 = 65536 // 64KB
leveldb_compression = false
leveldb_log = ""
OSDs will still maintain the following osd-specific defaults:
leveldb_log = ""
* CephFS support for the legacy anchor table has finally been removed.
Users with file systems created before firefly should ensure that inodes
with multiple hard links are modified *prior* to the upgrade to ensure that
the backtraces are written properly. For example::
sudo find /mnt/cephfs -type f -links +1 -exec touch \{\} \;
* We disallow nonsensical 'tier cache-mode' transitions. From this point
onward, 'writeback' can only transition to 'forward' and 'forward'
can transition to 1) 'writeback' if there are dirty objects, or 2) any if
there are no dirty objects.

v0.86
=====
This is a release candidate for Giant, which will hopefully be out
in another week or two. We did a feature freeze about a month ago
and since then have been doing only stabilization and bug fixing (and
a handful on low-risk enhancements). A fair bit of new functionality
went into the final sprint, but it's baked for quite a while now and
we're feeling pretty good about it.
Major items include:
* librados locking refactor to improve scaling and client performance
* local recovery code (LRC) erasure code plugin to trade some
additional storage overhead for improved recovery performance
* LTTNG tracing framework, with initial tracepoints in librados,
librbd, and the OSD FileStore backend
* separate monitor audit log for all administrative commands
* asynchronos monitor transaction commits to reduce the impact on
monitor read requests while processing updates
* low-level tool for working with individual OSD data stores for
debugging, recovery, and testing
* many MDS improvements (bug fixes, health reporting)
There are still a handful of known bugs in this release, but nothing
severe enough to prevent a release. By and large we are pretty
pleased with the stability and expect the final Giant release to be
quite reliable.
Please try this out on your non-production clusters for a preview

v0.85
=====
This is the second-to-last development release before Giant that
contains new functionality. The big items to land during this cycle
are the messenger refactoring from Matt Benjmain that lays some
groundwork for RDMA support, a performance improvement series from
SanDisk that improves performance on SSDs, lots of improvements to our
new standalone civetweb-based RGW frontend, and a new 'osd blocked-by'
mon command that allows admins to easily identify which OSDs are
blocking peering progress. The other big change is that the OSDs and
Monitors now distinguish between "misplaced" and "degraded" objects:
the latter means there are fewer copies than we'd like, while the
former simply means the are not stored in the locations where we want
them to be.
Also of note is a change to librbd that enables client-side caching by
default. This is coupled with another option that makes the cache
write-through until a "flush" operations is observed: this implies
that the librbd user (usually a VM guest OS) supports barriers and
flush and that it is safe for the cache to switch into writeback mode
without compromising data safety or integrity. It has long been
recommended practice that these options be enabled (e.g., in OpenStack
environments) but until now it has not been the default.
We have frozen the tree for the looming Giant release, and the next
development release will be a release candidate with a final batch of
new functionality.
Upgrading
---------
* The client-side caching for librbd is now enabled by default (rbd
cache = true). A safety option (rbd cache writethrough until flush
= true) is also enabled so that writeback caching is not used until
the library observes a 'flush' command, indicating that the librbd
users is passing that operation through from the guest VM. This
avoids potential data loss when used with older versions of qemu
that do not support flush.
leveldb_write_buffer_size = 32*1024*1024 = 33554432 // 32MB
leveldb_cache_size = 512*1024*1204 = 536870912 // 512MB
leveldb_block_size = 64*1024 = 65536 // 64KB
leveldb_compression = false
leveldb_log = ""
OSDs will still maintain the following osd-specific defaults:
leveldb_log = ""
* The 'rados getxattr ...' command used to add a gratuitous newline to the attr
value; it now does not.

v0.84
=====
The next Ceph development release is here! This release contains
several meaty items, including some MDS improvements for journaling,
the ability to remove the CephFS file system (and name it), several
mon cleanups with tiered pools, several OSD performance branches, a
new "read forward" RADOS caching mode, a prototype Kinetic OSD
backend, and various radosgw improvements (especially with the new
standalone civetweb frontend). And there are a zillion OSD bug
fixes. Things are looking pretty good for the Giant release that is
coming up in the next month.
Upgrading
---------
* The ``*_kb perf`` counters on the monitor have been removed. These are
replaced with a new set of ``*_bytes`` counters (e.g., ``cluster_osd_kb`` is
replaced by ``cluster_osd_bytes``).
* The ``rd_kb`` and ``wr_kb`` fields in the JSON dumps for pool stats (accessed
via the ``ceph df detail -f json-pretty`` and related commands) have been
replaced with corresponding ``*_bytes`` fields. Similarly, the
``total_space``, ``total_used``, and ``total_avail`` fields are replaced with
``total_bytes``, ``total_used_bytes``, and ``total_avail_bytes`` fields.
* The ``rados df --format=json`` output ``read_bytes`` and ``write_bytes``
fields were incorrectly reporting ops; this is now fixed.
* The ``rados df --format=json`` output previously included ``read_kb`` and
``write_kb`` fields; these have been removed. Please use ``read_bytes`` and
``write_bytes`` instead (and divide by 1024 if appropriate).

v0.83
=====
Another Ceph development release! This has been a longer cycle, so
there has been quite a bit of bug fixing and stabilization in this
round. There is also a bunch of packaging fixes for RPM distros
(RHEL/CentOS, Fedora, and SUSE) and for systemd. We've also added a new
librados-striper library from Sebastien Ponce that provides a generic
striping API for applications to code to.
Upgrading
---------
* The experimental keyvaluestore-dev OSD backend had an on-disk format
change that prevents existing OSD data from being upgraded. This
affects developers and testers only.
* mon-specific and osd-specific leveldb options have been removed.
From this point onward users should use the `leveldb_*` generic
options and add the options in the appropriate sections of their
configuration files. Monitors will still maintain the following
monitor-specific defaults:
leveldb_write_buffer_size = 32*1024*1024 = 33554432 // 32MB
leveldb_cache_size = 512*1024*1204 = 536870912 // 512MB
leveldb_block_size = 64*1024 = 65536 // 64KB
leveldb_compression = false
leveldb_log = ""
OSDs will still maintain the following osd-specific defaults:
leveldb_log = ""

v0.81
=====
This is the first development release since Firefly. It includes a
lot of work that we delayed merging while stabilizing things. Lots of
new functionality, as well as several fixes that are baking a bit before
getting backported.
Upgrading
---------
* CephFS support for the legacy anchor table has finally been removed.
Users with file systems created before firefly should ensure that inodes
with multiple hard links are modified *prior* to the upgrade to ensure that
the backtraces are written properly. For example::
sudo find /mnt/cephfs -type f -links +1 -exec touch \{\} \;
* Disallow nonsensical 'tier cache-mode' transitions. From this point
onward, 'writeback' can only transition to 'forward' and 'forward'
can transition to 1) 'writeback' if there are dirty objects, or 2) any if
there are no dirty objects.

v0.80.9 Firefly
===============
This is a bugfix release for firefly. It fixes a performance
regression in librbd, an important CRUSH misbehavior (see below), and
several RGW bugs. We have also backported support for flock/fcntl
locks to ceph-fuse and libcephfs.
We recommend that all Firefly users upgrade.
For more detailed information, see :download:`the complete changelog <changelog/v0.80.9.txt>`.
Adjusting CRUSH maps
--------------------
* This point release fixes several issues with CRUSH that trigger
excessive data migration when adjusting OSD weights. These are most
obvious when a very small weight change (e.g., a change from 0 to
.01) triggers a large amount of movement, but the same set of bugs
can also lead to excessive (though less noticeable) movement in
other cases.
However, because the bug may already have affected your cluster,
fixing it may trigger movement *back* to the more correct location.
For this reason, you must manually opt-in to the fixed behavior.
In order to set the new tunable to correct the behavior::
ceph osd crush set-tunable straw_calc_version 1
Note that this change will have no immediate effect. However, from
this point forward, any 'straw' bucket in your CRUSH map that is
adjusted will get non-buggy internal weights, and that transition
may trigger some rebalancing.
You can estimate how much rebalancing will eventually be necessary
on your cluster with::
ceph osd getcrushmap -o /tmp/cm
crushtool -i /tmp/cm --num-rep 3 --test --show-mappings > /tmp/a 2>&1
crushtool -i /tmp/cm --set-straw-calc-version 1 -o /tmp/cm2
crushtool -i /tmp/cm2 --reweight -o /tmp/cm2
crushtool -i /tmp/cm2 --num-rep 3 --test --show-mappings > /tmp/b 2>&1
wc -l /tmp/a # num total mappings
diff -u /tmp/a /tmp/b | grep -c ^+ # num changed mappings
Divide the number of changed lines by the total number of lines in
/tmp/a. We've found that most clusters are under 10%.
You can force all of this rebalancing to happen at once with::
ceph osd crush reweight-all
Otherwise, it will happen at some unknown point in the future when
CRUSH weights are next adjusted.

v0.80.4 Firefly
===============
This Firefly point release fixes an potential data corruption problem
when ceph-osd daemons run on top of XFS and service Firefly librbd
clients. A recently added allocation hint that RBD utilizes triggers
an XFS bug on some kernels (Linux 3.2, and likely others) that leads
to data corruption and deep-scrub errors (and inconsistent PGs). This
release avoids the situation by disabling the allocation hint until we
can validate which kernels are affected and/or are known to be safe to
use the hint on.
We recommend that all v0.80.x Firefly users urgently upgrade,
especially if they are using RBD.
Notable Changes
---------------
* osd: disable XFS extsize hint by default (#8830, Samuel Just)
* rgw: fix extra data pool default name (Yehuda Sadeh)

v0.80.3 Firefly
===============
This is the third Firefly point release. It includes a single fix
for a radosgw regression that was discovered in v0.80.2 right after it
was released.
We recommand that all v0.80.x Firefly users upgrade.
Notable Changes
---------------
* radosgw: fix regression in manifest decoding (#8804, Sage Weil)
For more detailed information, see :download:`the complete changelog <changelog/v0.80.3.txt>`.
v0.80.2 Firefly
===============
This is the second Firefly point release. It contains a range of
important fixes, including several bugs in the OSD cache tiering, some
compatibility checks that affect upgrade situations, several radosgw
bugs, and an irritating and unnecessary feature bit check that
prevents older clients from communicating with a cluster with any
erasure coded pools.
One someone large change in this point release is that the ceph RPM
package is separated into a ceph and ceph-common package, similar to
Debian. The ceph-common package contains just the client libraries
without any of the server-side daemons.
We recommend that all v0.80.x Firefly users skip this release and use
v0.80.3.

v0.80 Firefly
=============
This release will form the basis for our long-term supported release
Firefly, v0.80.x. The big new features are support for erasure coding
and cache tiering, although a broad range of other features, fixes,
and improvements have been made across the code base. Highlights include:
* *Erasure coding*: support for a broad range of erasure codes for lower
storage overhead and better data durability.
* *Cache tiering*: support for creating 'cache pools' that store hot,
recently accessed objects with automatic demotion of colder data to
a base tier. Typically the cache pool is backed by faster storage
devices like SSDs.
* *Primary affinity*: Ceph now has the ability to skew selection of
OSDs as the "primary" copy, which allows the read workload to be
cheaply skewed away from parts of the cluster without migrating any
data.
* *Key/value OSD backend* (experimental): An alternative storage backend
for Ceph OSD processes that puts all data in a key/value database like
leveldb. This provides better performance for workloads dominated by
key/value operations (like radosgw bucket indices).
* *Standalone radosgw* (experimental): The radosgw process can now run
in a standalone mode without an apache (or similar) web server or
fastcgi. This simplifies deployment and can improve performance.
We expect to maintain a series of stable releases based on v0.80
Firefly for as much as a year. In the meantime, development of Ceph
continues with the next release, Giant, which will feature work on the
CephFS distributed file system, more alternative storage backends
(like RocksDB and f2fs), RDMA support, support for pyramid erasure
codes, and additional functionality in the block device (RBD) like
copy-on-read and multisite mirroring.
Upgrade Sequencing
------------------
* If your existing cluster is running a version older than v0.67
Dumpling, please first upgrade to the latest Dumpling release before
upgrading to v0.80 Firefly. Please refer to the `Dumpling upgrade`_
documentation.
* We recommand adding the following to the [mon] section of your
ceph.conf prior to upgrade::
mon warn on legacy crush tunables = false
This will prevent health warnings due to the use of legacy CRUSH
placement. Although it is possible to rebalance existing data
across your cluster (see the upgrade notes below), we do not
normally recommend it for production environments as a large amount
of data will move and there is a significant performance impact from
the rebalancing.
* Upgrade daemons in the following order:
#. Monitors
#. OSDs
#. MDSs and/or radosgw
If the ceph-mds daemon is restarted first, it will wait until all
OSDs have been upgraded before finishing its startup sequence. If
the ceph-mon daemons are not restarted prior to the ceph-osd
daemons, they will not correctly register their new capabilities
with the cluster and new features may not be usable until they are
restarted a second time.
* Upgrade radosgw daemons together. There is a subtle change in behavior
for multipart uploads that prevents a multipart request that was initiated
with a new radosgw from being completed by an old radosgw.
Upgrading from v0.79
--------------------
* OSDMap's json-formatted dump changed for keys 'full' and 'nearfull'.
What was previously being outputted as 'true' or 'false' strings are
now being outputted 'true' and 'false' booleans according to json syntax.
* HEALTH_WARN on 'mon osd down out interval == 0'. Having this option set
to zero on the leader acts much like having the 'noout' flag set. This
warning will only be reported if the monitor getting the 'health' or
'status' request has this option set to zero.
* Monitor 'auth' commands now require the mon 'x' capability. This matches
dumpling v0.67.x and earlier, but differs from emperor v0.72.x.
* A librados WATCH operation on a non-existent object now returns ENOENT;
previously it did not.
* Librados interface change: As there are no partial writes, the rados_write()
and rados_append() operations now return 0 on success like rados_write_full()
always has. This includes the C++ interface equivalents and AIO return
values for the aio variants.
* The radosgw init script (sysvinit) how requires that the 'host = ...' line in
ceph.conf, if present, match the short hostname (the output of 'hostname -s'),
not the fully qualified hostname or the (occasionally non-short) output of
'hostname'. Failure to adjust this when upgrading from emperor or dumpling
may prevent the radosgw daemon from starting.
Upgrading from v0.72 Emperor
----------------------------
* See notes above.
* The 'ceph -s' or 'ceph status' command's 'num_in_osds' field in the
JSON and XML output has been changed from a string to an int.
* The recently added 'ceph mds set allow_new_snaps' command's syntax
has changed slightly; it is now 'ceph mds set allow_new_snaps true'.
The 'unset' command has been removed; instead, set the value to
'false'.
* The syntax for allowing snapshots is now 'mds set allow_new_snaps
<true|false>' instead of 'mds <set,unset> allow_new_snaps'.
* 'rbd ls' on a pool which never held rbd images now exits with code
0. It outputs nothing in plain format, or an empty list in
non-plain format. This is consistent with the behavior for a pool
which used to hold images, but contains none. Scripts relying on
this behavior should be updated.
* The MDS requires a new OSD operation TMAP2OMAP, added in this release. When
upgrading, be sure to upgrade and restart the ceph-osd daemons before the
ceph-mds daemon. The MDS will refuse to start if any up OSDs do not support
the new feature.
* The 'ceph mds set_max_mds N' command is now deprecated in favor of
'ceph mds set max_mds N'.
* The 'osd pool create ...' syntax has changed for erasure pools.
* The default CRUSH rules and layouts are now using the 'bobtail'
tunables and defaults. Upgaded clusters using the old values will
now present with a health WARN state. This can be disabled by
adding 'mon warn on legacy crush tunables = false' to ceph.conf and
restarting the monitors. Alternatively, you can switch to the new
tunables with 'ceph osd crush tunables firefly,' but keep in mind
that this will involve moving a *significant* portion of the data
already stored in the cluster and in a large cluster may take
several days to complete. We do not recommend adjusting tunables on a
production cluster.
* We now default to the 'bobtail' CRUSH tunable values that are first supported
by Ceph clients in bobtail (v0.56) and Linux kernel version v3.9. If you
plan to access a newly created Ceph cluster with an older kernel client, you
should use 'ceph osd crush tunables legacy' to switch back to the legacy
behavior. Note that making that change will likely result in some data
movement in the system, so adjust the setting before populating the new
cluster with data.
* We now set the HASHPSPOOL flag on newly created pools (and new
clusters) by default. Support for this flag first appeared in
v0.64; v0.67 Dumpling is the first major release that supports it.
It is first supported by the Linux kernel version v3.9. If you plan
to access a newly created Ceph cluster with an older kernel or
clients (e.g, librados, librbd) from a pre-dumpling Ceph release,
you should add 'osd pool default flag hashpspool = false' to the
'[global]' section of your 'ceph.conf' prior to creating your
monitors (e.g., after 'ceph-deploy new' but before 'ceph-deploy mon
create ...').
* The configuration option 'osd pool default crush rule' is deprecated
and replaced with 'osd pool default crush replicated ruleset'. 'osd
pool default crush rule' takes precedence for backward compatibility
and a deprecation warning is displayed when it is used.
* As part of fix for #6796, 'ceph osd pool set <pool> <var> <arg>' now
receives <arg> as an integer instead of a string. This affects how
'hashpspool' flag is set/unset: instead of 'true' or 'false', it now
must be '0' or '1'.
* The behavior of the CRUSH 'indep' choose mode has been changed. No
ceph cluster should have been using this behavior unless someone has
manually extracted a crush map, modified a CRUSH rule to replace
'firstn' with 'indep', recompiled, and reinjected the new map into
the cluster. If the 'indep' mode is currently in use on a cluster,
the rule should be modified to use 'firstn' instead, and the
administrator should wait until any data movement completes before
upgrading.
* The 'osd dump' command now dumps pool snaps as an array instead of an
object.
Upgrading from v0.67 Dumpling
-----------------------------
* See notes above.
* ceph-fuse and radosgw now use the same default values for the admin
socket and log file paths that the other daemons (ceph-osd,
ceph-mon, etc.) do. If you run these daemons as non-root, you may
need to adjust your ceph.conf to disable these options or to adjust
the permissions on /var/run/ceph and /var/log/ceph.
* The MDS now disallows snapshots by default as they are not
considered stable. The command 'ceph mds set allow_snaps' will
enable them.
* For clusters that were created before v0.44 (pre-argonaut, Spring
2012) and store radosgw data, the auto-upgrade from TMAP to OMAP
objects has been disabled. Before upgrading, make sure that any
buckets created on pre-argonaut releases have been modified (e.g.,
by PUTing and then DELETEing an object from each bucket). Any
cluster created with argonaut (v0.48) or a later release or not
using radosgw never relied on the automatic conversion and is not
affected by this change.
* Any direct users of the 'tmap' portion of the librados API should be
aware that the automatic tmap -> omap conversion functionality has
been removed.
* Most output that used K or KB (e.g., for kilobyte) now uses a
lower-case k to match the official SI convention. Any scripts that
parse output and check for an upper-case K will need to be modified.
* librados::Rados::pool_create_async() and librados::Rados::pool_delete_async()
don't drop a reference to the completion object on error, caller needs to take
care of that. This has never really worked correctly and we were leaking an
object
* 'ceph osd crush set <id> <weight> <loc..>' no longer adds the osd to the
specified location, as that's a job for 'ceph osd crush add'. It will
however continue to work just the same as long as the osd already exists
in the crush map.
* The OSD now enforces that class write methods cannot both mutate an
object and return data. The rbd.assign_bid method, the lone
offender, has been removed. This breaks compatibility with
pre-bobtail librbd clients by preventing them from creating new
images.
* librados now returns on commit instead of ack for synchronous calls.
This is a bit safer in the case where both OSDs and the client crash, and
is probably how it should have been acting from the beginning. Users are
unlikely to notice but it could result in lower performance in some
circumstances. Those who care should switch to using the async interfaces,
which let you specify safety semantics precisely.
* The C++ librados AioComplete::get_version() method was incorrectly
returning an int (usually 32-bits). To avoid breaking library
compatibility, a get_version64() method is added that returns the
full-width value. The old method is deprecated and will be removed
in a future release. Users of the C++ librados API that make use of
the get_version() method should modify their code to avoid getting a
value that is truncated from 64 to to 32 bits.

v0.79
=====
This release is intended to serve as a release candidate for firefly,
which will hopefully be v0.80. No changes are being made to the code
base at this point except those that fix bugs. Please test this
release if you intend to make use of the new erasure-coded pools or
cache tiers in firefly.
This release fixes a range of bugs found in v0.78 and streamlines the
user experience when creating erasure-coded pools. There is also a
raft of fixes for the MDS (multi-mds, directory fragmentation, and
large directories). The main notable new piece of functionality is a
small change to allow radosgw to use an erasure-coded pool for object
data.
Upgrading
---------
* Erasure pools created with v0.78 will no longer function with v0.79. You
will need to delete the old pool and create a new one.
* A bug was fixed in the authentication handshake with big-endian
architectures that prevent authentication between big- and
little-endian machines in the same cluster. If you have a cluster
that consists entirely of big-endian machines, you will need to
upgrade all daemons and clients and restart.
* The 'ceph.file.layout' and 'ceph.dir.layout' extended attributes are
no longer included in the listxattr(2) results to prevent problems with
'cp -a' and similar tools.
* Monitor 'auth' read-only commands now expect the user to have 'rx' caps.
This is the same behavior that was present in dumpling, but in emperor
and more recent development releases the 'r' cap was sufficient. The
affected commands are::
ceph auth export
ceph auth get
ceph auth get-key
ceph auth print-key
ceph auth list
Notable Changes
---------------
* ceph-conf: stop creating bogus log files (Josh Durgin, Sage Weil)
* common: fix authentication on big-endian architectures (Dan Mick)
* debian: change directory ownership between ceph and ceph-common (Sage Weil)
* init: fix startup ordering/timeout problem with OSDs (Dmitry Smirnov)
* librbd: skip zeroes/holes when copying sparse images (Josh Durgin)

* mds: misc fixes for larger directories (Zheng Yan)
* mds: misc fixes for multiple MDSs (Zheng Yan)
* mds: remove .ceph directory (John Spray)

* osd: reduce scrub lock contention (Guang Yang)
* rgw: allow use of an erasure data pool (Yehuda Sadeh)
v0.78
=====
This development release includes two key features: erasure coding and
cache tiering. A huge amount of code was merged for this release and
several additional weeks were spent stabilizing the code base, and it
is now in a state where it is ready to be tested by a broader user
base.
This is *not* the firefly release. Firefly will be delayed for at
least another sprint so that we can get some operational experience
with the new code and do some additional testing before committing to
long term support.
.. note:: Please note that while it is possible to create and test
erasure coded pools in this release, the pools will not be
usable when you upgrade to v0.79 as the OSDMap encoding will
subtlely change. Please do not populate your test pools
with important data that can't be reloaded.
Upgrading
---------
* Upgrade daemons in the following order:
#. Monitors
#. OSDs
#. MDSs and/or radosgw
If the ceph-mds daemon is restarted first, it will wait until all
OSDs have been upgraded before finishing its startup sequence. If
the ceph-mon daemons are not restarted prior to the ceph-osd
daemons, they will not correctly register their new capabilities
with the cluster and new features may not be usable until they are
restarted a second time.
* Upgrade radosgw daemons together. There is a subtle change in behavior
for multipart uploads that prevents a multipart request that was initiated
with a new radosgw from being completed by an old radosgw.
* CephFS recently added support for a new 'backtrace' attribute on
file data objects that is used for lookup by inode number (i.e., NFS
reexport and hard links), and will later be used by fsck repair.
This replaces the existing anchor table mechanism that is used for
hard link resolution. In order to completely phase that out, any
inode that has an outdated backtrace attribute will get updated when
the inode itself is modified. This will result in some extra workload
after a legacy CephFS file system is upgraded.
* The per-op return code in librados' ObjectWriteOperation interface
is now filled in.
* The librados cmpxattr operation now handles xattrs containing null bytes as
data rather than null-terminated strings.
* Compound operations in librados that create and then delete the same object
are now explicitly disallowed (they fail with -EINVAL).
* The default leveldb cache size for the ceph-osd daemon has been
increased from 4 MB to 128 MB. This will increase the memory
footprint of that process but tends to increase performance of omap
(key/value) objects (used for CephFS and the radosgw). If memory in your
deployment is tight, you can preserve the old behavio by adding::
leveldb write buffer size = 0
leveldb cache size = 0
to your ceph.conf to get back the (leveldb) defaults.

v0.77
=====
This is the final development release before the Firefly feature
freeze. The main items in this release include some additional
refactoring work in the OSD IO path (include some locking
improvements), per-user quotas for the radosgw, a switch to civetweb
from mongoose for the prototype radosgw standalone mode, and a
prototype leveldb-based backend for the OSD. The C librados API also
got support for atomic write operations (read side transactions will
appear in v0.78).
Upgrading
---------
* The 'ceph -s' or 'ceph status' command's 'num_in_osds' field in the
JSON and XML output has been changed from a string to an int.
* The recently added 'ceph mds set allow_new_snaps' command's syntax
has changed slightly; it is now 'ceph mds set allow_new_snaps true'.
The 'unset' command has been removed; instead, set the value to
'false'.
* The syntax for allowing snapshots is now 'mds set allow_new_snaps
<true|false>' instead of 'mds <set,unset> allow_new_snaps'.
Notable Changes
---------------
* osd: client IO path changes for EC (Samuel Just)
* common: portability changes to support libc++ (Noah Watkins)

v0.76
=====
This release includes another batch of updates for firefly
functionality. Most notably, the cache pool infrastructure now
support snapshots, the OSD backfill functionality has been generalized
to include multiple targets (necessary for the coming erasure pools),
and there were performance improvements to the erasure code plugin on
capable processors. The MDS now properly utilizes (and seamlessly
migrates to) the OSD key/value interface (aka omap) for storing directory
objects. There continue to be many other fixes and improvements for
usability and code portability across the tree.
Upgrading
---------
* 'rbd ls' on a pool which never held rbd images now exits with code
0. It outputs nothing in plain format, or an empty list in
non-plain format. This is consistent with the behavior for a pool
which used to hold images, but contains none. Scripts relying on
this behavior should be updated.
* The MDS requires a new OSD operation TMAP2OMAP, added in this release. When
upgrading, be sure to upgrade and restart the ceph-osd daemons before the
ceph-mds daemon. The MDS will refuse to start if any up OSDs do not support
the new feature.
* The 'ceph mds set_max_mds N' command is now deprecated in favor of
'ceph mds set max_mds N'.

v0.75
=====
This is a big release, with lots of infrastructure going in for
firefly. The big items include a prototype standalone frontend for
radosgw (which does not require apache or fastcgi), tracking for read
activity on the osds (to inform tiering decisions), preliminary cache
pool support (no snapshots yet), and lots of bug fixes and other work
across the tree to get ready for the next batch of erasure coding
patches.
For comparison, here are the diff stats for the last few versions::
v0.75 291 files changed, 82713 insertions(+), 33495 deletions(-)
v0.74 192 files changed, 17980 insertions(+), 1062 deletions(-)
v0.73 148 files changed, 4464 insertions(+), 2129 deletions(-)
Upgrading
---------
- The 'osd pool create ...' syntax has changed for erasure pools.
- The default CRUSH rules and layouts are now using the latest and
greatest tunables and defaults. Clusters using the old values will
now present with a health WARN state. This can be disabled by
adding 'mon warn on legacy crush tunables = false' to ceph.conf.

v0.74
=====
This release includes a few substantial pieces for Firefly, including
a long-overdue switch to 3x replication by default and a switch to the
"new" CRUSH tunables by default (supported since bobtail). There is
also a fix for a long-standing radosgw bug (stalled GET) that has
already been backported to emperor and dumpling.
Upgrading
---------
* We now default to the 'bobtail' CRUSH tunable values that are first supported
by Ceph clients in bobtail (v0.56) and Linux kernel version v3.9. If you
plan to access a newly created Ceph cluster with an older kernel client, you
should use 'ceph osd crush tunables legacy' to switch back to the legacy
behavior. Note that making that change will likely result in some data
movement in the system, so adjust the setting before populating the new
cluster with data.
* We now set the HASHPSPOOL flag on newly created pools (and new
clusters) by default. Support for this flag first appeared in
v0.64; v0.67 Dumpling is the first major release that supports it.
It is first supported by the Linux kernel version v3.9. If you plan
to access a newly created Ceph cluster with an older kernel or
clients (e.g, librados, librbd) from a pre-dumpling Ceph release,
you should add 'osd pool default flag hashpspool = false' to the
'[global]' section of your 'ceph.conf' prior to creating your
monitors (e.g., after 'ceph-deploy new' but before 'ceph-deploy mon
create ...').
* The configuration option 'osd pool default crush rule' is deprecated
and replaced with 'osd pool default crush replicated ruleset'. 'osd
pool default crush rule' takes precedence for backward compatibility
and a deprecation warning is displayed when it is used.
Notable Changes
---------------
* buffer: some zero-copy groundwork (Josh Durgin)
* ceph-disk: avoid fd0 (Loic Dachary)
* crush: default to bobtail tunables (Sage Weil)
* crush: many additional tests (Loic Dachary)
* crush: misc fixes, cleanups (Loic Dachary)
* crush: new rule steps to adjust retry attempts (Sage Weil)
* debian: integrate misc fixes from downstream packaging (James Page)
* doc: big update to install docs (John Wilkins)

* mon: add 'mon getmap EPOCH' (Joao Eduardo Luis)
* mon: collect misc metadata about osd (os, kernel, etc.), new 'osd metadata' command (Sage Weil)
* osd: default to 3x replication
* osd: do not include backfill targets in acting set (David Zafman)
* osd: new 'chassis' type in default crush hierarchy (Sage Weil)
* osd: requery unfound on stray notify (#6909) (Samuel Just)

* rgw: fix reading bucket policy (#6940)
* rgw: fix use-after-free when releasing completion handle (Yehuda Sadeh)
v0.73
=====
This release, the first development release after emperor, includes
many bug fixes and a few additional pieces of functionality. The
first batch of larger changes will be landing in the next version,
v0.74.
Upgrading
---------
- As part of fix for #6796, 'ceph osd pool set <pool> <var> <arg>' now
receives <arg> as an integer instead of a string. This affects how
'hashpspool' flag is set/unset: instead of 'true' or 'false', it now
must be '0' or '1'.
- The behavior of the CRUSH 'indep' choose mode has been changed. No
ceph cluster should have been using this behavior unless someone has
manually extracted a crush map, modified a CRUSH rule to replace
'firstn' with 'indep', recompiled, and reinjected the new map into
the cluster. If the 'indep' mode is currently in use on a cluster,
the rule should be modified to use 'firstn' instead, and the
administrator should wait until any data movement completes before
upgrading.
- The 'osd dump' command now dumps pool snaps as an array instead of an
object.
- The radosgw init script (sysvinit) how requires that the 'host = ...' line in
ceph.conf, if present, match the short hostname (the output of 'hostname -s'),
not the fully qualified hostname or the (occasionally non-short) output of
'hostname'. Failure to adjust this when upgrading from emperor or dumpling
may prevent the radosgw daemon from starting.
Notable Changes
---------------
* ceph-crush-location: new hook for setting CRUSH location of osd daemons on start
* ceph-kvstore-tool: expanded command set and capabilities (Joao Eduardo Luis)
* ceph.spec: fix build dependency (Loic Dachary)
* common: fix aligned buffer allocation (Loic Dachary)
* doc: many many install doc improvements (John Wilkins)
* mds: fix readdir end check (Zheng Yan)
* mds: update old-format backtraces opportunistically (Zheng Yan)
* misc cleanups from coverity (Xing Lin)
* misc portability fixes (Noah Watkins, Christophe Courtaut, Alan Somers, huanjun)
* mon: 'osd dump' dumps pool snaps as array, not object (Dan Mick)
* mon: allow debug quorum_{enter,exit} commands via admin socket
* mon: prevent extreme changes in pool pg_num (Greg Farnum)
* mon: take 'osd pool set ...' value as an int, not string (Joao Eduardo Luis)
* mon: trim MDSMaps (Joao Eduardo Luis)
* osd: fix object_info_t encoding bug from emperor (Sam Just)
* rbd: add 'rbdmap' init script for mapping rbd images on book (Adam Twardowski)
* rgw: add 'status' command to sysvinit script (David Moreau Simard)
* rgw: fix error setting empty owner on ACLs (Yehuda Sadeh)
* rgw: optionally defer to bucket ACLs instead of object ACLs (Liam Monahan)
* rgw: support for password (instead of admin token) for keystone authentication (Christophe Courtaut)
* sysvinit, upstart: prevent both init systems from starting the same daemons (Josh Durgin)
v0.72.3 Emperor (pending release)
=================================
Upgrading
---------
* Monitor 'auth' read-only commands now expect the user to have 'rx' caps.
This is the same behavior that was present in dumpling, but in emperor
and more recent development releases the 'r' cap was sufficient. Note that
this backported security fix will break mon keys that are using the following
commands but do not have the 'x' bit in the mon capability::
ceph auth export
ceph auth get
ceph auth get-key
ceph auth print-key
ceph auth list
v0.72.2 Emperor
===============
This is the second bugfix release for the v0.72.x Emperor series. We
have fixed a hang in radosgw, and fixed (again) a problem with monitor
CLI compatiblity with mixed version monitors. (In the future this
will no longer be a problem.)
Upgrading
---------
* The JSON schema for the 'osd pool set ...' command changed slightly. Please
avoid issuing this particular command via the CLI while there is a mix of
v0.72.1 and v0.72.2 monitor daemons running.
* As part of fix for #6796, 'ceph osd pool set <pool> <var> <arg>' now
receives <arg> as an integer instead of a string. This affects how
'hashpspool' flag is set/unset: instead of 'true' or 'false', it now
must be '0' or '1'.
Changes
-------
* mon: 'osd pool set ...' syntax change
* osd: added test for missing on-disk HEAD object
* osd: fix osd bench block size argument
* rgw: fix hang on large object GET
* rgw: fix rare use-after-free
* rgw: various DR bug fixes
* rgw: do not return error on empty owner when setting ACL
* sysvinit, upstart: prevent starting daemons using both init systems
For more detailed information, see :download:`the complete changelog <changelog/v0.72.2.txt>`.
v0.72.1 Emperor
===============
Important Note
--------------
When you are upgrading from Dumpling to Emperor, do not run any of the
"ceph osd pool set" commands while your monitors are running separate versions.
Doing so could result in inadvertently changing cluster configuration settings
that exhaust compute resources in your OSDs.
Changes
-------
* osd: fix upgrade bug #6761
* ceph_filestore_tool: introduced tool to repair errors caused by #6761
This release addresses issue #6761. Upgrading to Emperor can cause
reads to begin returning ENFILE (too many open files). v0.72.1 fixes
that upgrade issue and adds a tool ceph_filestore_tool to repair osd
stores affected by this bug.
To repair a cluster affected by this bug:
#. Upgrade all osd machines to v0.72.1
#. Install the ceph-test package on each osd machine to get ceph_filestore_tool
#. Stop all osd processes
#. To see all lost objects, run the following on each osd with the osd stopped and
the osd data directory mounted::
ceph_filestore_tool --list-lost-objects=true --filestore-path=<path-to-osd-filestore> --journal-path=<path-to-osd-journal>
#. To fix all lost objects, run the following on each osd with the
osd stopped and the osd data directory mounted::
ceph_filestore_tool --fix-lost-objects=true --list-lost-objects=true --filestore-path=<path-to-osd-filestore> --journal-path=<path-to-osd-journal>
#. Once lost objects have been repaired on each osd, you can restart
the cluster.
Note, the ceph_filestore_tool performs a scan of all objects on the
osd and may take some time.
v0.72 Emperor
=============
This is the fifth major release of Ceph, the fourth since adopting a
3-month development cycle. This release brings several new features,
including multi-datacenter replication for the radosgw, improved
usability, and lands a lot of incremental performance and internal
refactoring work to support upcoming features in Firefly.
Important Note
--------------
When you are upgrading from Dumpling to Emperor, do not run any of the
"ceph osd pool set" commands while your monitors are running separate versions.
Doing so could result in inadvertently changing cluster configuration settings
that exhaust compute resources in your OSDs.
Highlights
----------
* common: improved crc32c performance
* librados: new example client and class code
* mds: many bug fixes and stability improvements
* mon: health warnings when pool pg_num values are not reasonable
* mon: per-pool performance stats
* osd, librados: new object copy primitives
* osd: improved interaction with backend file system to reduce latency
* osd: much internal refactoring to support ongoing erasure coding and tiering support
* rgw: bucket quotas
* rgw: improved CORS support
* rgw: performance improvements
* rgw: validate S3 tokens against Keystone
Coincident with core Ceph, the Emperor release also brings:
* radosgw-agent: support for multi-datacenter replication for disaster recovery
* tgt: improved support for iSCSI via upstream tgt
Packages for both are available on ceph.com.
Upgrade sequencing
------------------
There are no specific upgrade restrictions on the order or sequence of
upgrading from 0.67.x Dumpling. However, you cannot run any of the
"ceph osd pool set" commands while your monitors are running separate versions.
Doing so could result in inadvertently changing cluster configuration settings
and exhausting compute resources in your OSDs.
It is also possible to do a rolling upgrade from 0.61.x Cuttlefish,
but there are ordering restrictions. (This is the same set of
restrictions for Cuttlefish to Dumpling.)
#. Upgrade ceph-common on all nodes that will use the command line 'ceph' utility.
#. Upgrade all monitors (upgrade ceph package, restart ceph-mon
daemons). This can happen one daemon or host at a time. Note that
because cuttlefish and dumpling monitors can't talk to each other,
all monitors should be upgraded in relatively short succession to
minimize the risk that an a untimely failure will reduce
availability.
#. Upgrade all osds (upgrade ceph package, restart ceph-osd daemons).
This can happen one daemon or host at a time.
#. Upgrade radosgw (upgrade radosgw package, restart radosgw daemons).
Upgrading from v0.71
--------------------
* ceph-fuse and radosgw now use the same default values for the admin
socket and log file paths that the other daemons (ceph-osd,
ceph-mon, etc.) do. If you run these daemons as non-root, you may
need to adjust your ceph.conf to disable these options or to adjust
the permissions on /var/run/ceph and /var/log/ceph.
Upgrading from v0.67 Dumpling
-----------------------------
* ceph-fuse and radosgw now use the same default values for the admin
socket and log file paths that the other daemons (ceph-osd,
ceph-mon, etc.) do. If you run these daemons as non-root, you may
need to adjust your ceph.conf to disable these options or to adjust
the permissions on /var/run/ceph and /var/log/ceph.
* The MDS now disallows snapshots by default as they are not
considered stable. The command 'ceph mds set allow_snaps' will
enable them.
* For clusters that were created before v0.44 (pre-argonaut, Spring
2012) and store radosgw data, the auto-upgrade from TMAP to OMAP
objects has been disabled. Before upgrading, make sure that any
buckets created on pre-argonaut releases have been modified (e.g.,
by PUTing and then DELETEing an object from each bucket). Any
cluster created with argonaut (v0.48) or a later release or not
using radosgw never relied on the automatic conversion and is not
affected by this change.
* Any direct users of the 'tmap' portion of the librados API should be
aware that the automatic tmap -> omap conversion functionality has
been removed.
* Most output that used K or KB (e.g., for kilobyte) now uses a
lower-case k to match the official SI convention. Any scripts that
parse output and check for an upper-case K will need to be modified.
* librados::Rados::pool_create_async() and librados::Rados::pool_delete_async()
don't drop a reference to the completion object on error, caller needs to take
care of that. This has never really worked correctly and we were leaking an
object
* 'ceph osd crush set <id> <weight> <loc..>' no longer adds the osd to the
specified location, as that's a job for 'ceph osd crush add'. It will
however continue to work just the same as long as the osd already exists
in the crush map.
* The OSD now enforces that class write methods cannot both mutate an
object and return data. The rbd.assign_bid method, the lone
offender, has been removed. This breaks compatibility with
pre-bobtail librbd clients by preventing them from creating new
images.
* librados now returns on commit instead of ack for synchronous calls.
This is a bit safer in the case where both OSDs and the client crash, and
is probably how it should have been acting from the beginning. Users are
unlikely to notice but it could result in lower performance in some
circumstances. Those who care should switch to using the async interfaces,
which let you specify safety semantics precisely.
* The C++ librados AioComplete::get_version() method was incorrectly
returning an int (usually 32-bits). To avoid breaking library
compatibility, a get_version64() method is added that returns the
full-width value. The old method is deprecated and will be removed
in a future release. Users of the C++ librados API that make use of
the get_version() method should modify their code to avoid getting a
value that is truncated from 64 to to 32 bits.

v0.71
=====
This development release includes a significant amount of new code and
refactoring, as well as a lot of preliminary functionality that will be needed
for erasure coding and tiering support. There are also several significant
patch sets improving this with the MDS.
Upgrading
---------
* The MDS now disallows snapshots by default as they are not
considered stable. The command 'ceph mds set allow_snaps' will
enable them.
* For clusters that were created before v0.44 (pre-argonaut, Spring
2012) and store radosgw data, the auto-upgrade from TMAP to OMAP
objects has been disabled. Before upgrading, make sure that any
buckets created on pre-argonaut releases have been modified (e.g.,
by PUTing and then DELETEing an object from each bucket). Any
cluster created with argonaut (v0.48) or a later release or not
using radosgw never relied on the automatic conversion and is not
affected by this change.
* Any direct users of the 'tmap' portion of the librados API should be
aware that the automatic tmap -> omap conversion functionality has
been removed.
* Most output that used K or KB (e.g., for kilobyte) now uses a
lower-case k to match the official SI convention. Any scripts that
parse output and check for an upper-case K will need to be modified.
Notable Changes
---------------
* build: Makefile refactor (Roald J. van Loon)

v0.70
=====
Upgrading
---------
* librados::Rados::pool_create_async() and librados::Rados::pool_delete_async()
don't drop a reference to the completion object on error, caller needs to take
care of that. This has never really worked correctly and we were leaking an
object
* 'ceph osd crush set <id> <weight> <loc..>' no longer adds the osd to the
specified location, as that's a job for 'ceph osd crush add'. It will
however continue to work just the same as long as the osd already exists
in the crush map.
Notable Changes
---------------
* mon: a few 'ceph mon add' races fixed (command is now idempotent) (Joao Luis)
* crush: fix name caching
* rgw: fix a few minor memory leaks (Yehuda Sadeh)
* ceph: improve parsing of CEPH_ARGS (Benoit Knecht)
* mon: avoid rewriting full osdmaps on restart (Joao Luis)
* crc32c: fix optimized crc32c code (it now detects arch support properly)
* mon: fix 'ceph osd crush reweight ...' (Joao Luis)
* osd: revert xattr size limit (fixes large rgw uploads)
* mds: fix heap profiler commands (Joao Luis)
* rgw: fix inefficient use of std::list::size() (Yehuda Sadeh)
v0.69
=====
Upgrading
---------
* The sysvinit /etc/init.d/ceph script will, by default, update the
CRUSH location of an OSD when it starts. Previously, if the
monitors were not available, this command would hang indefinitely.
Now, that step will time out after 10 seconds and the ceph-osd daemon
will not be started.
* Users of the librados C++ API should replace users of get_version()
with get_version64() as the old method only returns a 32-bit value
for a 64-bit field. The existing 32-bit get_version() method is now
deprecated.
* The OSDs are now more picky that request payload match their
declared size. A write operation across N bytes that includes M
bytes of data will now be rejected. No known clients do this, but
the because the server-side behavior has changed it is possible that
an application misusing the interface may now get errors.
* The OSD now enforces that class write methods cannot both mutate an
object and return data. The rbd.assign_bid method, the lone
offender, has been removed. This breaks compatibility with
pre-bobtail librbd clients by preventing them from creating new
images.
* librados now returns on commit instead of ack for synchronous calls.
This is a bit safer in the case where both OSDs and the client crash, and
is probably how it should have been acting from the beginning. Users are
unlikely to notice but it could result in lower performance in some
circumstances. Those who care should switch to using the async interfaces,
which let you specify safety semantics precisely.
* The C++ librados AioComplete::get_version() method was incorrectly
returning an int (usually 32-bits). To avoid breaking library
compatibility, a get_version64() method is added that returns the
full-width value. The old method is deprecated and will be removed
in a future release. Users of the C++ librados API that make use of
the get_version() method should modify their code to avoid getting a
value that is truncated from 64 to to 32 bits.

v0.67.12 "Dumpling" (draft)
===========================
This stable update for Dumpling fixes a few longstanding issues with
backfill in the OSD that can lead to stalled IOs. There is also a fix
for memory utilization for reads in librbd when caching is enabled,
and then several other small fixes across the rest of the system.
Dumpling users who have encountered IO stalls during backfill and who
do not expect to upgrade to Firefly soon should upgrade. Everyone
else should upgrade to Firefly already. This is likely to be the last stable
release for the 0.67.x Dumpling series.

network failure detection with the monitor, and several hard to hit
OSD crashes or hangs.
We recommend that all users upgrade at their convenience.
Upgrading
---------
* The 'rbd ls' function now returns success and returns an empty when a pool
does not store any rbd images. Previously it would return an ENOENT error.
* Ceph will now issue a health warning if the 'mon osd down out
interval' config option is set to zero. This warning can be
disabled by adding 'mon warn on osd down out interval zero = false'
to ceph.conf.

v0.67.7 "Dumpling"
==================
This Dumpling point release fixes a few critical issues in v0.67.6.
All v0.67.6 users are urgently encouraged to upgrade. We also
recommend that all v0.67.5 (or older) users upgrade.
Upgrading
---------
* Once you have upgraded a radosgw instance or OSD to v0.67.7, you should not
downgrade to a previous version.
Notable Changes
---------------
* ceph-disk: additional unit tests
* librbd: revert caching behavior change in v0.67.6
* osd: fix problem reading xattrs due to incomplete backport in v0.67.6
* radosgw-admin: fix reading object policy
For more detailed information, see :download:`the complete changelog <changelog/v0.67.7.txt>`.
v0.67.6 "Dumpling"
==================
.. note: This release contains a librbd bug that is fixed in v0.67.7. Please upgrade to v0.67.7 and do not use v0.67.6.
This Dumpling point release contains a number of important fixed for
the OSD, monitor, and radosgw. Most significantly, a change that
forces large object attributes to spill over into leveldb has been
backported that can prevent objects and the cluster from being damaged
by large attributes (which can be induced via the radosgw). There is
also a set of fixes that improves data safety and RADOS semantics when
the cluster becomes full and then non-full.
We recommend that all 0.67.x Dumpling users skip this release and upgrade to v0.67.7.
Upgrading
---------
* The OSD has long contained a feature that allows large xattrs to
spill over into the leveldb backing store in situations where not
all local file systems are able to store them reliably. This option
is now enabled unconditionally in order to avoid rare cases where
storing large xattrs renders the object unreadable. This is known to
be triggered by very large multipart objects, but could be caused by
other workloads as well. Although there is some small risk that
performance for certain workloads will degrade, it is more important
that data be retrievable. Note that newer versions of Ceph (e.g.,
firefly) do some additional work to avoid the potential performance
regression in this case, but that is current considered too complex
for backport to the Dumpling stable series.
* It is very dangerous to downgrade from v0.67.6 to a prior version of
Dumpling. If the old version does not have 'filestore xattr use
omap = true' it may not be able to read all xattrs for an object and
can cause undefined behavior.
Notable changes
---------------
* ceph-disk: misc bug fixes, particularly on RHEL (Loic Dachary, Alfredo Deza, various)
* ceph-fuse, libcephfs: fix crash from read over certain sparseness patterns (Sage Weil)

v0.67.5 "Dumpling"
==================
This release includes a few critical bug fixes for the radosgw,
including a fix for hanging operations on large objects. There are also
several bug fixes for radosgw multi-site replications, and a few
backported features. Also, notably, the 'osd perf' command (which dumps
recent performance information about active OSDs) has been backported.

This point release fixes a few important performance regressions with
the OSD (both with CPU and disk utilization), as well as several other
important but less common problems. We recommend that all production users
upgrade.
Notable Changes
---------------
* ceph-disk: partprobe after creation journal partition
* ceph-disk: specify fs type when mounting
* ceph-post-file: new utility to help share logs and other files with ceph developers
* libcephfs: fix truncate vs readahead race (crash)
* mds: fix flock/fcntl lock deadlock
* mds: fix rejoin loop when encountering pre-dumpling backpointers
* mon: allow name and addr discovery during election stage
* mon: always refresh after Paxos store_state (fixes recovery corner case)
* mon: fix off-by-4x bug with osd byte counts
* osd: add and disable 'pg log keys debug' by default
* osd: add option to disable throttling
* osd: avoid leveldb iterators for pg log append and trim
* osd: fix readdir_r invocations
* osd: use fdatasync instead of sync
* radosgw: fix sysvinit script return status
* rbd: relicense as LGPL2
* rgw: flush pending data on multipart upload
* rgw: recheck object name during S3 POST
* rgw: reorder init/startup
* rpm: fix debuginfo package build

v0.67.2 "Dumpling"
==================
This is an imporant point release for Dumpling. Most notably, it
fixes a problem when upgrading directly from v0.56.x Bobtail to
v0.67.x Dumpling (without stopping at v0.61.x Cuttlefish along the
way). It also fixes a problem with the CLI parsing of the CEPH_ARGS
environment variable, high CPU utilization by the ceph-osd daemons,
and cleans up the radosgw shutdown sequence.
Notable Changes
---------------
* objecter: resend linger requests when cluster goes from full to non-full
* ceph: parse CEPH_ARGS environment variable
* librados: fix small memory leak
* osd: remove old log objects on upgrade (fixes bobtail -> dumpling jump)
* osd: disable PGLog::check() via config option (fixes CPU burn)
* rgw: drain requests on shutdown
* rgw: misc memory leaks on shutdown
For more detailed information, see :download:`the complete changelog <changelog/v0.67.2.txt>`.
v0.67.1 "Dumpling"
==================
This is a minor point release for Dumpling that fixes problems with
OpenStack and librbd hangs when caching is disabled.
Notable changes
---------------
* librados, librbd: fix constructor for python bindings with certain
usages (in particular, that used by OpenStack)
* librados, librbd: fix aio_flush wakeup when cache is disabled
* librados: fix locking for aio completion refcounting
* fixes 'ceph --admin-daemon ...' command error code on error
* fixes 'ceph daemon ... config set ...' command for boolean config
options.
For more detailed information, see :download:`the complete changelog <changelog/v0.67.1.txt>`.
v0.67 "Dumpling"
================
This is the fourth major release of Ceph, code-named "Dumpling." The
headline features for this release include:
* Multi-site support for radosgw. This includes the ability to set up
separate "regions" in the same or different Ceph clusters that share
a single S3/Swift bucket/container namespace.
* RESTful API endpoint for Ceph cluster administration.
ceph-rest-api, a wrapper around ceph_rest_api.py, can be used to
start up a test single-threaded HTTP server that provides access to
cluster information and administration in very similar ways to the
ceph commandline tool. ceph_rest_api.py can be used as a WSGI
application for deployment in a more-capable web server. See
ceph-rest-api.8 for more.
* Object namespaces in librados.
.. _Dumpling upgrade:
Upgrade Sequencing
------------------
It is possible to do a rolling upgrade from Cuttlefish to Dumpling.
#. Upgrade ceph-common on all nodes that will use the command line
'ceph' utility.
#. Upgrade all monitors (upgrade ceph package, restart ceph-mon
daemons). This can happen one daemon or host at a time. Note that
because cuttlefish and dumpling monitors can't talk to each other,
all monitors should be upgraded in relatively short succession to
minimize the risk that an a untimely failure will reduce
availability.
#. Upgrade all osds (upgrade ceph package, restart ceph-osd daemons).
This can happen one daemon or host at a time.
#. Upgrade radosgw (upgrade radosgw package, restart radosgw daemons).
Upgrading from v0.66
--------------------
* There is monitor internal protocol change, which means that v0.67
ceph-mon daemons cannot talk to v0.66 or older daemons. We
recommend upgrading all monitors at once (or in relatively quick
succession) to minimize the possibility of downtime.
* The output of 'ceph status --format=json' or 'ceph -s --format=json'
has changed to return status information in a more structured and
usable format.
* The 'ceph pg dump_stuck [threshold]' command used to require a
--threshold or -t prefix to the threshold argument, but now does
not.
* Many more ceph commands now output formatted information; select
with '--format=<format>', where <format> can be 'json', 'json-pretty',
'xml', or 'xml-pretty'.
* The 'ceph pg <pgid> ...' commands (like 'ceph pg <pgid> query') are
deprecated in favor of 'ceph tell <pgid> ...'. This makes the
distinction between 'ceph pg <command> <pgid>' and 'ceph pg <pgid>
<command>' less awkward by making it clearer that the 'tell'
commands are talking to the OSD serving the placement group, not the
monitor.
* The 'ceph --admin-daemon <path> <command ...>' used to accept the
command and arguments as either a single string or as separate
arguments. It will now only accept the command spread across
multiple arguments. This means that any script which does something
like::
ceph --admin-daemon /var/run/ceph/ceph-osd.0.asok 'config set debug_ms 1'
needs to remove the quotes. Also, note that the above can now be
shortened to::
ceph daemon osd.0 config set debug_ms 1
* The radosgw caps were inconsistently documented to be either 'mon =
allow r' or 'mon = allow rw'. The 'mon = allow rw' is required for
radosgw to create its own pools. All documentation has been updated
accordingly.
* The radosgw copy object operation may return extra progress info
during the operation. At this point it will only happen when doing
cross zone copy operations. The S3 response will now return extra
<Progress> field under the <CopyResult> container. The Swift
response will now send the progress as a json array.
* In v0.66 and v0.65 the HASHPSPOOL pool flag was enabled by default
for new pools, but has been disabled again until Linux kernel client
support reaches more distributions and users.
* ceph-osd now requires a max file descriptor limit (e.g., ``ulimit -n
...``) of at least
filestore_wbthrottle_(xfs|btrfs)_inodes_hard_limit (5000 by default)
in order to accomodate the new write back throttle system. On
Ubuntu, upstart now sets the fd limit to 32k. On other platforms,
the sysvinit script will set it to 32k by default (still
overrideable via max_open_files). If this field has been customized
in ceph.conf it should likely be adjusted upwards.
Upgrading from v0.61 "Cuttlefish"
---------------------------------
In addition to the above notes about upgrading from v0.66:
* There has been a huge revamp of the 'ceph' command-line interface
implementation. The ``ceph-common`` client library needs to be
upgrade before ``ceph-mon`` is restarted in order to avoid problems
using the CLI (the old ``ceph`` client utility cannot talk to the
new ``ceph-mon``).
* The CLI is now very careful about sending the 'status' one-liner
output to stderr and command output to stdout. Scripts relying on
output should take care.
* The 'ceph osd tell ...' and 'ceph mon tell ...' commands are no
longer supported. Any callers should use::
ceph tell osd.<id or *> ...
ceph tell mon.<id or name or *> ...
The 'ceph mds tell ...' command is still there, but will soon also
transition to 'ceph tell mds.<id or name or \*> ...'
* The 'ceph osd crush add ...' command used to take one of two forms::
ceph osd crush add 123 osd.123 <weight> <location ...>
ceph osd crush add osd.123 <weight> <location ...>
This is because the id and crush name are redundant. Now only the
simple form is supported, where the osd name/id can either be a bare
id (integer) or name (osd.<id>)::
ceph osd crush add osd.123 <weight> <location ...>
ceph osd crush add 123 <weight> <location ...>
* There is now a maximum RADOS object size, configurable via 'osd max
object size', defaulting to 100 GB. Note that this has no effect on
RBD, CephFS, or radosgw, which all stripe over objects. If you are
using librados and storing objects larger than that, you will need
to adjust 'osd max object size', and should consider using smaller
objects instead.
* The 'osd min down {reporters|reports}' config options have been
renamed to 'mon osd min down {reporters|reports}', and the
documentation has been updated to reflect that these options apply
to the monitors (who process failure reports) and not OSDs. If you
have adjusted these settings, please update your ``ceph.conf``
accordingly.

v0.64
=====
Upgrading
---------
* New pools now have the HASHPSPOOL flag set by default to provide
better distribution over OSDs. Support for this feature was
introduced in v0.59 and Linux kernel version v3.9. If you wish to
access the cluster from an older kernel, set the 'osd pool default
flag hashpspool = false' option in your ceph.conf prior to creating
the cluster or creating new pools. Note that the presense of any
pool in the cluster with the flag enabled will make the OSD require
support from all clients.

v0.61.8 "Cuttlefish"
====================
This release includes a number of important issues, including rare
race conditions in the OSD, a few monitor bugs, and fixes for RBD
flush behavior. We recommend that production users upgrade at their
convenience.
Notable Changes
---------------
* librados: fix async aio completion wakeup
* librados: fix aio completion locking
* librados: fix rare deadlock during shutdown
* osd: fix race when queueing recovery operations
* osd: fix possible race during recovery
* osd: optionally preload rados classes on startup (disabled by default)
* osd: fix journal replay corner condition
* osd: limit size of peering work queue batch (to speed up peering)
* mon: fix paxos recovery corner case

* msgr: fix race conditions during osd network reinitialization
* ceph-disk: apply mount options when remounting
For more detailed information, see :download:`the complete changelog <changelog/v0.61.8.txt>`.
v0.61.7 "Cuttlefish"
====================
This release fixes another regression preventing monitors to start after
undergoing certain upgrade sequences, as well as some corner cases with
Paxos and support for unusual device names in ceph-disk/ceph-deploy.
Notable Changes
---------------
* mon: fix regression in latest full osdmap retrieval
* mon: fix a long-standing bug in a paxos corner case
* ceph-disk: improved support for unusual device names (e.g., /dev/cciss/c0d0)
For more detailed information, see :download:`the complete changelog <changelog/v0.61.7.txt>`.
v0.61.6 "Cuttlefish"
====================
This release fixes a regression in v0.61.5 that could prevent monitors
from restarting. This affects any cluster that was upgraded from a
previous version of Ceph (and not freshly created with v0.61.5).
All users are strongly recommended to upgrade.
Notable Changes
---------------
* mon: record latest full osdmap
* mon: work around previous bug in which latest full osdmap is not recorded
* mon: avoid scrub while updating
For more detailed information, see :download:`the complete changelog <changelog/v0.61.6.txt>`.
v0.61.5 "Cuttlefish"
====================
This release most improves stability of the monitor and fixes a few
bugs with the ceph-disk utility (used by ceph-deploy). We recommand
that all v0.61.x users upgrade.
Upgrading
---------
* This release fixes a 32-bit vs 64-bit arithmetic bug with the
feature bits. An unfortunate consequence of the fix is that 0.61.4
(or earlier) ceph-mon daemons can't form a quorum with 0.61.5 (or
later) monitors. To avoid the possibility of service disruption, we
recommend you upgrade all monitors at once.
Notable Changes
---------------
* mon: misc sync improvements (faster, more reliable, better tuning)
* mon: enable leveldb cache by default (big performance improvement)
* mon: new scrub feature (primarily for diagnostic, testing purposes)
* mon: fix occasional leveldb assertion on startup
* mon: prevent reads until initial state is committed
* mon: improved logic for trimming old osdmaps

v0.61.4 "Cuttlefish"
====================
This release resolves a possible data corruption on power-cycle when
using XFS, a few outstanding problems with monitor sync, several
problems with ceph-disk and ceph-deploy operation, and a problem with
OSD memory usage during scrub.
Upgrading
---------
* No issues.
Notable Changes
---------------
* mon: fix daemon exit behavior when error is encountered on startup
* mon: more robust sync behavior
* osd: do not use sync_file_range(2), posix_fadvise(...DONTNEED) (can cause data corruption on power loss on XFS)
* osd: avoid unnecessary log rewrite (improves peering speed)
* osd: fix scrub efficiency bug (problematic on old clusters)
* rgw: fix listing objects that start with underscore
* rgw: fix deep URI resource, CORS bugs
* librados python binding: fix truncate on 32-bit architectures
* ceph-disk: fix udev rules
* rpm: install sysvinit script on package install
* ceph-disk: fix OSD start on machine reboot on Debian wheezy
* ceph-disk: activate OSD when journal device appears second
* ceph-disk: fix various bugs on RHEL/CentOS 6.3
* ceph-disk: add 'zap' command
* ceph-disk: add '[un]suppress-activate' command for preparing spare disks
* upstart: start on runlevel [2345] (instead of after the first network interface starts)
* ceph-fuse, libcephfs: handle mds session reset during session open
* ceph-fuse, libcephfs: fix two capability revocation bugs
* ceph-fuse: fix thread creation on startup
* all daemons: create /var/run/ceph directory on startup if missing
For more detailed information, see :download:`the complete changelog <changelog/v0.61.4.txt>`.
v0.61.3 "Cuttlefish"
====================
This release resolves a number of problems with the monitors and leveldb that users have
been seeing. Please upgrade.
Upgrading
---------
* There is one known problem with mon upgrades from bobtail. If the
ceph-mon conversion on startup is aborted or fails for some reason, we
do not correctly error out, but instead continue with (in certain cases)
odd results. Please be careful if you have to restart the mons during
the upgrade. A 0.61.4 release with a fix will be out shortly.
* In the meantime, for current cuttlefish users, v0.61.3 is safe to use.
Notable Changes
---------------
* mon: paxos state trimming fix (resolves runaway disk usage)
* mon: finer-grained compaction on trim
* mon: discard messages from disconnected clients (lowers load)
* mon: leveldb compaction and other stats available via admin socket
* mon: async compaction (lower overhead)
* mon: fix bug incorrectly marking osds down with insufficient failure reports
* osd: fixed small bug in pg request map
* osd: avoid rewriting pg info on every osdmap
* osd: avoid internal heartbeta timeouts when scrubbing very large objects
* osd: fix narrow race with journal replay
* mon: fixed narrow pg split race
* rgw: fix leaked space when copying object
* rgw: fix iteration over large/untrimmed usage logs
* rgw: fix locking issue with ops log socket
* rgw: require matching version of librados
* librbd: make image creation defaults configurable (e.g., create format 2 images via qemu-img)
* fix units in 'ceph df' output
* debian: fix prerm/postinst hooks to start/stop daemons appropriately
* upstart: allow uppercase daemons names (and thus hostnames)
* sysvinit: fix enumeration of local daemons by type
* sysvinit: fix osd weight calcuation when using -a
* fix build on unsigned char platforms (e.g., arm)
For more detailed information, see :download:`the complete changelog <changelog/v0.61.3.txt>`.
v0.61.2 "Cuttlefish"
====================
This release disables a monitor debug log that consumes disk space and
fixes a bug when upgrade some monitors from bobtail to cuttlefish.
Notable Changes
---------------
* mon: fix conversion of stores with duplicated GV values
* mon: disable 'mon debug dump transactions' by default
For more detailed information, see :download:`the complete changelog <changelog/v0.61.2.txt>`.
v0.61.1 "Cuttlefish"
====================
This release fixes a problem when upgrading a bobtail cluster that had
snapshots to cuttlefish.
Notable Changes
---------------
* osd: handle upgrade when legacy snap collections are present; repair from previous failed restart
* ceph-create-keys: fix race with ceph-mon startup (which broke 'ceph-deploy gatherkeys ...')
* ceph-create-keys: gracefully handle bad response from ceph-osd
* sysvinit: do not assume default osd_data when automatically weighting OSD
* osd: avoid crash from ill-behaved classes using getomapvals
* debian: fix squeeze dependency
* mon: debug options to log or dump leveldb transactions
For more detailed information, see :download:`the complete changelog <changelog/v0.61.1.txt>`.
v0.61 "Cuttlefish"
==================
Upgrading from v0.60
--------------------
* The ceph-deploy tool is now the preferred method of provisioning
new clusters. For existing clusters created via mkcephfs that
would like to transition to the new tool, there is a migration
path, documented at `Transitioning to ceph-deploy`_.
* The sysvinit script (/etc/init.d/ceph) will now verify (and, if
necessary, update) the OSD's position in the CRUSH map on startup.
(The upstart script has always worked this way.) By default, this
ensures that the OSD is under a 'host' with a name that matches the
hostname (``hostname -s``). Legacy clusters create with mkcephfs do
this by default, so this should not cause any problems, but legacy
clusters with customized CRUSH maps with an alternate structure
should set ``osd crush update on start = false``.
* radosgw-admin now uses the term zone instead of cluster to describe
each instance of the radosgw data store (and corresponding
collection of radosgw daemons). The usage for the radosgw-admin
command and the 'rgw zone root pool' config options have changed
accordingly.
* rbd progress indicators now go to standard error instead of standard
out. (You can disable progress with --no-progress.)
* The 'rbd resize ...' command now requires the --allow-shrink option
when resizing to a smaller size. Expanding images to a larger size
is unchanged.
* Please review the changes going back to 0.56.4 if you are upgrading
all the way from bobtail.
* The old 'ceph stop_cluster' command has been removed.
* The sysvinit script now uses the ceph.conf file on the remote host
when starting remote daemons via the '-a' option. Note that if '-a'
is used in conjunction with '-c path', the path must also be present
on the remote host (it is not copied to a temporary file, as it was
previously).
Upgrading from v0.56.4 "Bobtail"
--------------------------------
Please see `Upgrading from Bobtail to Cuttlefish`_ for details.
.. _Upgrading from Bobtail to Cuttlefish: ../install/upgrading-ceph/#upgrading-from-bobtail-to-cuttlefish
* The ceph-deploy tool is now the preferred method of provisioning
new clusters. For existing clusters created via mkcephfs that
would like to transition to the new tool, there is a migration
path, documented at `Transitioning to ceph-deploy`_.

* radosgw-admin now uses the term zone instead of cluster to describe
each instance of the radosgw data store (and corresponding
collection of radosgw daemons). The usage for the radosgw-admin
command and the 'rgw zone root pool' config optoins have changed

* The 'rbd resize ...' command now requires the --allow-shrink option
when resizing to a smaller size. Expanding images to a larger size
is unchanged.
* Please review the changes going back to 0.56.4 if you are upgrading
all the way from bobtail.
* The old 'ceph stop_cluster' command has been removed.
* The sysvinit script now uses the ceph.conf file on the remote host
when starting remote daemons via the '-a' option. Note that if '-a'
is used in conjuction with '-c path', the path must also be present
on the remote host (it is not copied to a temporary file, as it was
previously).
* The monitor is using a completely new storage strategy and
intra-cluster protocol. This means that cuttlefish and bobtail
monitors do not talk to each other. When you upgrade each one, it
will convert its local data store to the new format. Once you
upgrade a majority, the quorum will be formed using the new protocol
and the old monitors will be blocked out until they too get
upgraded. For this reason, we recommend not running a mixed-version
cluster for very long.
* ceph-mon now requires the creation of its data directory prior to
--mkfs, similarly to what happens on ceph-osd. This directory is no
longer automatically created, and custom scripts should be adjusted to
reflect just that.
* The monitor now enforces that MDS names be unique. If you have
multiple daemons start with with the same id (e.g., ``mds.a``) the
second one will implicitly mark the first as failed. This makes
things less confusing and makes a daemon restart faster (we no
longer wait for the stopped daemon to time out) but existing
multi-mds configurations may need to be adjusted accordingly to give
daemons unique names.
* The 'ceph osd pool delete <poolname>' and 'rados rmpool <poolname>'
now have safety interlocks with loud warnings that make you confirm
pool removal. Any scripts curenty rely on these functions zapping
data without confirmation need to be adjusted accordingly.

For more detailed information, see :download:`the complete changelog <changelog/v0.56.5.txt>`.
v0.56.4 "bobtail"
=================
Upgrading
---------
* There is a fix in the syntax for the output of 'ceph osd tree --format=json'.
* The MDS disk format has changed from prior releases *and* from v0.57. In particular,
upgrades to v0.56.4 are safe, but you cannot move from v0.56.4 to v0.57 if you are using
the MDS for CephFS; you must upgrade directly to v0.58 (or later) instead.
Notable changes
---------------
* mon: fix bug in bringup with IPv6
* reduce default memory utilization by internal logging (all daemons)
* rgw: fix for bucket removal
* rgw: reopen logs after log rotation
* rgw: fix multipat upload listing
* rgw: don't copy object when copied onto self
* osd: fix caps parsing for pools with - or _
* osd: allow pg log trimming when degraded, scrubbing, recoverying (reducing memory consumption)
* osd: fix potential deadlock when 'journal aio = true'
* osd: various fixes for collection creation/removal, rename, temp collections
* osd: various fixes for PG split
* osd: deep-scrub omap key/value data
* osd: fix rare bug in journal replay
* osd: misc fixes for snapshot tracking
* osd: fix leak in recovery reservations on pool deletion
* osd: fix bug in connection management
* osd: fix for op ordering when rebalancing
* ceph-fuse: report file system size with correct units
* mds: get and set directory layout policies via virtual xattrs
* mds: on-disk format revision (see upgrading note above)
* mkcephfs, init-ceph: close potential security issues with predictable filenames
For more detailed information, see :download:`the complete changelog <changelog/v0.56.4.txt>`.
v0.56.3 "bobtail"
=================
This release has several bug fixes surrounding OSD stability. Most
significantly, an issue with OSDs being unresponsive shortly after
startup (and occasionally crashing due to an internal heartbeat check)
is resolved. Please upgrade.
Upgrading
---------
* A bug was fixed in which the OSDMap epoch for PGs without any IO
requests was not recorded. If there are pools in the cluster that
are completely idle (for example, the ``data`` and ``metadata``
pools normally used by CephFS), and a large number of OSDMap epochs
have elapsed since the ``ceph-osd`` daemon was last restarted, those
maps will get reprocessed when the daemon restarts. This process
can take a while if there are a lot of maps. A workaround is to
'touch' any idle pools with IO prior to restarting the daemons after
packages are upgraded::
rados bench 10 write -t 1 -b 4096 -p {POOLNAME}
This will typically generate enough IO to touch every PG in the pool
without generating significant cluster load, and also cleans up any
temporary objects it creates.
Notable changes
---------------
* osd: flush peering work queue prior to start
* osd: persist osdmap epoch for idle PGs
* osd: fix and simplify connection handling for heartbeats
* osd: avoid crash on invalid admin command
* mon: fix rare races with monitor elections and commands
* mon: enforce that OSD reweights be between 0 and 1 (NOTE: not CRUSH weights)
* mon: approximate client, recovery bandwidth logging
* radosgw: fixed some XML formatting to conform to Swift API inconsistency
* radosgw: fix usage accounting bug; add repair tool
* radosgw: make fallback URI configurable (necessary on some web servers)
* librbd: fix handling for interrupted 'unprotect' operations
* mds, ceph-fuse: allow file and directory layouts to be modified via virtual xattrs
For more detailed information, see :download:`the complete changelog <changelog/v0.56.3.txt>`.
v0.56.2 "bobtail"
=================
This release has a wide range of bug fixes, stability improvements, and some performance improvements. Please upgrade.
Upgrading
---------
* The meaning of the 'osd scrub min interval' and 'osd scrub max
interval' has changed slightly. The min interval used to be
meaningless, while the max interval would only trigger a scrub if
the load was sufficiently low. Now, the min interval option works
the way the old max interval did (it will trigger a scrub after this
amount of time if the load is low), while the max interval will
force a scrub regardless of load. The default options have been
adjusted accordingly. If you have customized these in ceph.conf,
please review their values when upgrading.
* CRUSH maps that are generated by default when calling ``ceph-mon
--mkfs`` directly now distribute replicas across hosts instead of
across OSDs. Any provisioning tools that are being used by Ceph may
be affected, although probably for the better, as distributing across
hosts is a much more commonly sought behavior. If you use
``mkcephfs`` to create the cluster, the default CRUSH rule is still
inferred by the number of hosts and/or racks in the initial ceph.conf.
Notable changes
---------------
* osd: snapshot trimming fixes
* osd: scrub snapshot metadata
* osd: fix osdmap trimming
* osd: misc peering fixes
* osd: stop heartbeating with peers if internal threads are stuck/hung
* osd: PG removal is friendlier to other workloads
* osd: fix recovery start delay (was causing very slow recovery)
* osd: fix scheduling of explicitly requested scrubs
* osd: fix scrub interval config options
* osd: improve recovery vs client io tuning
* osd: improve 'slow request' warning detail for better diagnosis
* osd: default CRUSH map now distributes across hosts, not OSDs
* osd: fix crash on 32-bit hosts triggered by librbd clients
* librbd: fix error handling when talking to older OSDs
* mon: fix a few rare crashes
* ceph command: ability to easily adjust CRUSH tunables
* radosgw: object copy does not copy source ACLs
* rados command: fix omap command usage
* sysvinit script: set ulimit -n properly on remote hosts
* msgr: fix narrow race with message queuing
* fixed compilation on some old distros (e.g., RHEL 5.x)
For more detailed information, see :download:`the complete changelog <changelog/v0.56.2.txt>`.
v0.56.1 "bobtail"
=================
This release has two critical fixes. Please upgrade.
Upgrading
---------
* There is a protocol compatibility problem between v0.56 and any
other version that is now fixed. If your radosgw or RBD clients are
running v0.56, they will need to be upgraded too. If they are
running a version prior to v0.56, they can be left as is.
Notable changes
---------------
* osd: fix commit sequence for XFS, ext4 (or any other non-btrfs) to prevent data loss on power cycle or kernel panic
* osd: fix compatibility for CALL operation
* osd: process old osdmaps prior to joining cluster (fixes slow startup)
* osd: fix a couple of recovery-related crashes
* osd: fix large io requests when journal is in (non-default) aio mode
* log: fix possible deadlock in logging code
For more detailed information, see :download:`the complete changelog <changelog/v0.56.1.txt>`.
v0.56 "bobtail"
===============
Bobtail is the second stable release of Ceph, named in honor of the
`Bobtail Squid`: http://en.wikipedia.org/wiki/Bobtail_squid.
Key features since v0.48 "argonaut"
-----------------------------------
* Object Storage Daemon (OSD): improved threading, small-io performance, and performance during recovery
* Object Storage Daemon (OSD): regular "deep" scrubbing of all stored data to detect latent disk errors
* RADOS Block Device (RBD): support for copy-on-write clones of images.
* RADOS Block Device (RBD): better client-side caching.
* RADOS Block Device (RBD): advisory image locking
* Rados Gateway (RGW): support for efficient usage logging/scraping (for billing purposes)
* Rados Gateway (RGW): expanded S3 and Swift API coverage (e.g., POST, multi-object delete)
* Rados Gateway (RGW): improved striping for large objects
* Rados Gateway (RGW): OpenStack Keystone integration
* RPM packages for Fedora, RHEL/CentOS, OpenSUSE, and SLES
* mkcephfs: support for automatically formatting and mounting XFS and ext4 (in addition to btrfs)
Upgrading
---------
Please refer to the document `Upgrading from Argonaut to Bobtail`_ for details.
.. _Upgrading from Argonaut to Bobtail: ../install/upgrading-ceph/#upgrading-from-argonaut-to-bobtail
* Cephx authentication is now enabled by default (since v0.55).
Upgrading a cluster without adjusting the Ceph configuration will
likely prevent the system from starting up on its own. We recommend
first modifying the configuration to indicate that authentication is
disabled, and only then upgrading to the latest version.::
auth client required = none
auth service required = none
auth cluster required = none
* Ceph daemons can be upgraded one-by-one while the cluster is online
and in service.
* The ``ceph-osd`` daemons must be upgraded and restarted *before* any
``radosgw`` daemons are restarted, as they depend on some new
ceph-osd functionality. (The ``ceph-mon``, ``ceph-osd``, and
``ceph-mds`` daemons can be upgraded and restarted in any order.)
* Once each individual daemon has been upgraded and restarted, it
cannot be downgraded.
* The cluster of ``ceph-mon`` daemons will migrate to a new internal
on-wire protocol once all daemons in the quorum have been upgraded.
Upgrading only a majority of the nodes (e.g., two out of three) may
expose the cluster to a situation where a single additional failure
may compromise availability (because the non-upgraded daemon cannot
participate in the new protocol). We recommend not waiting for an
extended period of time between ``ceph-mon`` upgrades.
* The ops log and usage log for radosgw are now off by default. If
you need these logs (e.g., for billing purposes), you must enable
them explicitly. For logging of all operations to objects in the
``.log`` pool (see ``radosgw-admin log ...``)::
rgw enable ops log = true
For usage logging of aggregated bandwidth usage (see ``radosgw-admin
usage ...``)::
rgw enable usage log = true
* You should not create or use "format 2" RBD images until after all
``ceph-osd`` daemons have been upgraded. Note that "format 1" is
still the default. You can use the new ``ceph osd ls`` and
``ceph tell osd.N version`` commands to doublecheck your cluster.
``ceph osd ls`` will give a list of all OSD IDs that are part of the
cluster, and you can use that to write a simple shell loop to display
all the OSD version strings: ::
for i in $(ceph osd ls); do
ceph tell osd.${i} version
done
Compatibility changes
---------------------
* The 'ceph osd create [<uuid>]' command now rejects an argument that
is not a UUID. (Previously it would take take an optional integer
OSD id.) This correct syntax has been 'ceph osd create [<uuid>]'
since v0.47, but the older calling convention was being silently
ignored.
* The CRUSH map root nodes now have type ``root`` instead of type
``pool``. This avoids confusion with RADOS pools, which are not
directly related. Any scripts or tools that use the ``ceph osd
crush ...`` commands may need to be adjusted accordingly.
* The ``ceph osd pool create <poolname> <pgnum>`` command now requires
the ``pgnum`` argument. Previously this was optional, and would
default to 8, which was almost never a good number.
* Degraded mode (when there fewer than the desired number of replicas)
is now more configurable on a per-pool basis, with the min_size
parameter. By default, with min_size 0, this allows I/O to objects
with N - floor(N/2) replicas, where N is the total number of
expected copies. Argonaut behavior was equivalent to having min_size
= 1, so I/O would always be possible if any completely up to date
copy remained. min_size = 1 could result in lower overall
availability in certain cases, such as flapping network partitions.
* The sysvinit start/stop script now defaults to adjusting the max
open files ulimit to 16384. On most systems the default is 1024, so
this is an increase and won't break anything. If some system has a
higher initial value, however, this change will lower the limit.
The value can be adjusted explicitly by adding an entry to the
``ceph.conf`` file in the appropriate section. For example::
[global]
max open files = 32768
* 'rbd lock list' and 'rbd showmapped' no longer use tabs as
separators in their output.
* There is configurable limit on the number of PGs when creating a new
pool, to prevent a user from accidentally specifying a ridiculous
number for pg_num. It can be adjusted via the 'mon max pool pg num'
option on the monitor, and defaults to 65536 (the current max
supported by the Linux kernel client).
* The osd capabilities associated with a rados user have changed
syntax since 0.48 argonaut. The new format is mostly backwards
compatible, but there are two backwards-incompatible changes:
* specifying a list of pools in one grant, i.e.
'allow r pool=foo,bar' is now done in separate grants, i.e.
'allow r pool=foo, allow r pool=bar'.
* restricting pool access by pool owner ('allow r uid=foo') is
removed. This feature was not very useful and unused in practice.
The new format is documented in the ceph-authtool man page.
* 'rbd cp' and 'rbd rename' use rbd as the default destination pool,
regardless of what pool the source image is in. Previously they
would default to the same pool as the source image.
* 'rbd export' no longer prints a message for each object written. It
just reports percent complete like other long-lasting operations.
* 'ceph osd tree' now uses 4 decimal places for weight so output is
nicer for humans
* Several monitor operations are now idempotent:
* ceph osd pool create
* ceph osd pool delete
* ceph osd pool mksnap
* ceph osd rm
* ceph pg <pgid> revert

v0.54
=====
Upgrading
---------
* The osd capabilities associated with a rados user have changed
syntax since 0.48 argonaut. The new format is mostly backwards
compatible, but there are two backwards-incompatible changes:
* specifying a list of pools in one grant, i.e.
'allow r pool=foo,bar' is now done in separate grants, i.e.
'allow r pool=foo, allow r pool=bar'.
* restricting pool access by pool owner ('allow r uid=foo') is
removed. This feature was not very useful and unused in practice.
The new format is documented in the ceph-authtool man page.
* Bug fixes to the new osd capability format parsing properly validate
the allowed operations. If an existing rados user gets permissions
errors after upgrading, its capabilities were probably
misconfigured. See the ceph-authtool man page for details on osd
capabilities.
* 'rbd lock list' and 'rbd showmapped' no longer use tabs as
separators in their output.

For more detailed information, see :download:`the complete changelog <changelog/v0.48.2argonaut.txt>`.
v0.48.1 "argonaut"
==================
Upgrading
---------
* The radosgw usage trim function was effectively broken in v0.48. Earlier it would remove more usage data than what was requested. This is fixed in v0.48.1, but the fix is incompatible. The v0.48 radosgw-admin tool cannot be used to initiate the trimming; please use the v0.48.1 version.
* v0.48.1 now explicitly indicates support for the CRUSH_TUNABLES feature. No other version of Ceph requires this, yet, but future versions will when the tunables are adjusted from their historical defaults.
* There are no other compatibility changes between v0.48.1 and v0.48.
Notable changes
---------------
* mkcephfs: use default 'keyring', 'osd data', 'osd journal' paths when not specified in conf
* msgr: various fixes to socket error handling
* osd: reduce scrub overhead
* osd: misc peering fixes (past_interval sharing, pgs stuck in 'peering' states)
* osd: fail on EIO in read path (do not silently ignore read errors from failing disks)
* osd: avoid internal heartbeat errors by breaking some large transactions into pieces
* osd: fix osdmap catch-up during startup (catch up and then add daemon to osdmap)
* osd: fix spurious 'misdirected op' messages
* osd: report scrub status via 'pg ... query'
* rbd: fix race when watch registrations are resent
* rbd: fix rbd image id assignment scheme (new image data objects have slightly different names)

* rpm: add ceph-disk-{activate, prepare}
For more detailed information, see :download:`the complete changelog <changelog/v0.48.1argonaut.txt>`.
v0.48 "argonaut"
================
Upgrading
---------
* This release includes a disk format upgrade. Each ceph-osd daemon, upon startup, will migrate its locally stored data to the new format. This process can take a while (for large object counts, even hours), especially on non-btrfs file systems.
* To keep the cluster available while the upgrade is in progress, we recommend you upgrade a storage node or rack at a time, and wait for the cluster to recover each time. To prevent the cluster from moving data around in response to the OSD daemons being down for minutes or hours, you may want to::
ceph osd set noout
This will prevent the cluster from marking down OSDs as "out" and re-replicating the data elsewhere. If you do this, be sure to clear the flag when the upgrade is complete::
ceph osd unset noout
* There is a encoding format change internal to the monitor cluster. The monitor daemons are careful to switch to the new format only when all members of the quorum support it. However, that means that a partial quorum with new code may move to the new format, and a recovering monitor running old code will be unable to join (it will crash). If this occurs, simply upgrading the remaining monitor will resolve the problem.
* The ceph tool's -s and -w commands from previous versions are incompatible with this version. Upgrade your client tools at the same time you upgrade the monitors if you rely on those commands.
* It is not possible to downgrade from v0.48 to a previous version.
Notable changes
---------------
* osd: stability improvements
* osd: capability model simplification
* osd: simpler/safer --mkfs (no longer removes all files; safe to re-run on active osd)
* osd: potentially buggy FIEMAP behavior disabled by default
* rbd: caching improvements
* rbd: improved instrumentation
* rbd: bug fixes
* radosgw: new, scalable usage logging infrastructure
* radosgw: per-user bucket limits
* mon: streamlined process for setting up authentication keys
* mon: stability improvements
* mon: log message throttling
* doc: improved documentation (ceph, rbd, radosgw, chef, etc.)
* config: new default locations for daemon keyrings
* config: arbitrary variable substitutions
* improved 'admin socket' daemon admin interface (ceph --admin-daemon ...)
* chef: support for multiple monitor clusters
* upstart: basic support for monitors, mds, radosgw; osd support still a work in progress.
The new default keyring locations mean that when enabling authentication (``auth supported = cephx``), keyring locations do not need to be specified if the keyring file is located inside the daemon's data directory (``/var/lib/ceph/$type/ceph-$id`` by default).
There is also a lot of librbd code in this release that is laying the groundwork for the upcoming layering functionality, but is not actually used. Likewise, the upstart support is still incomplete and not recommended; we will backport that functionality later if it turns out to be non-disruptive.
