v9.0.1
|
||
======
|
||
|
||
This development release is delayed a bit due to tooling changes in the build
|
||
environment. As a result the next one (v9.0.2) will have a bit more work than
|
||
is usual.
|
||
|
||
Highlights here include lots of RGW Swift fixes, RBD feature work
|
||
surrounding the new object map feature, more CephFS snapshot fixes,
|
||
and a few important CRUSH fixes.

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

v0.94.2 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

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
|

||
|
||
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: 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().
|
||
|

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.

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
|
||

||
Upgrading
|
||

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.
|
||

||

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 total number of lines in /tmp/a with the number of lines
|
||
changed. 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.

v0.80.6 Firefly
|
||
===============
|
||
|
||
This is a major bugfix release for firefly, fixing a range of issues
|
||
in the OSD and monitor, particularly with cache tiering. There are

v0.80.5 Firefly
|
||
===============
|
||
|
||
This release fixes a few important bugs in the radosgw and fixes
|
||
several packaging and environment issues, including OSD log rotation,
|
||
systemd environments, and daemon restarts on upgrade.
|
||
|
||
We recommend that all v0.80.x Firefly users upgrade, particularly if they
|
||
are using upstart, systemd, or radosgw.
|
||
|
||
Notable Changes
|
||
---------------
|
||
|
||
* ceph-dencoder: do not needlessly link to librgw, librados, etc. (Sage Weil)
|
||
* do not needlessly link binaries to leveldb (Sage Weil)
|
||
* mon: fix mon crash when no auth keys are present (#8851, Joao Eduardo Luis)
|
||
* osd: fix cleanup (and avoid occasional crash) during shutdown (#7981, Sage Weil)
|
||
* osd: fix log rotation under upstart (Sage Weil)

|
||
|
||
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)
|
||
|
||

|
||
|
||
|
||
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
|
||
|
||

|
||
|
||
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'.
|
||
|
||

|

|
||
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.
|
||

|
||
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

||
---------------
|
||
|

|
||

|
||

|
||
* crush: many additional tests (Loic Dachary)
|
||

|
||

|
||

|
||
* 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)
|
||
* osd: some PGBackend infrastructure (Samuel Just)
|
||
* osd: support for new 'memstore' (memory-backed) backend (Sage Weil)
|
||
* rgw: fix fastcgi deadlock (do not return data from librados callback) (Yehuda Sadeh)
|
||
* 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
|
||

|
||
|
||
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.
|
||
|
||

|
||
|
||
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.

||
v0.67.8 "Dumpling"
|
||
==================
|
||
|
||
This Dumpling point release fixes several non-critical issues since
|
||
v0.67.7. The most notable bug fixes are an auth fix in librbd
|
||
(observed as an occasional crash from KVM), an improvement in the
|
||
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
|
||
|
||

|
||
|
||
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)

|
||
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.
|
||
|
||
We recommend that all 0.67.x Dumpling users upgrade.

||
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
|

environment variable, high CPU utilization by the ceph-osd daemons,
|
||
and cleans up the radosgw shutdown sequence.
|
||
|
||
Notable Changes

|
||
* rgw: drain requests on shutdown
|
||
* rgw: misc memory leaks on shutdown

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.

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.

v0.61.7 "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)

|
||
|
||
|
||
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

||
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)

|
||
* fix units in 'ceph df' output
|
||
* debian: fix prerm/postinst hooks to start/stop daemons appropriately
|
||
* upstart: allow uppercase daemons names (and thus hostnames)

|
||
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
|
||

|
||
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`_.

|

|

|
||
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
|
||
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 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.
|
||
|
||
|

|

|
||
|
||
v0.59
|
||
=====
|
||
|
||
Upgrading
|
||
---------
|
||
|
||
* The monitor is using a completely new storage strategy and
|
||
intra-cluster protocol. This means that v0.59 and pre-v0.59
|
||
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.
|
||
|
||
|
||

|

|
||
|
||
v0.58
|
||
=====
|
||
|
||
Upgrading
|
||
---------
|
||
|
||
* 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.
|
||
|

|
||
|
||
v0.57
|
||
=====
|
||
|
||
This development release has a lot of additional functionality
|
||
accumulated over the last couple months. Most of the bug fixes (with
|
||
the notable exception of the MDS related work) has already been
|
||
backported to v0.56.x, and is not mentioned here.
|
||
|
||
Upgrading
|
||
---------
|
||
|
||
* 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.
|
||
|

|
||

|
||
|
||

|
||
=================
|
||
|
||
Upgrading
|
||
---------
|
||
|
||
* ceph-disk[-prepare,-activate] behavior has changed in various ways.
|
||
There should not be any compatibility issues, but chef users should

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

|
||
|
||
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
|
||

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

|
||

||
|
||
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
|
||
|
||

|
||
|
||
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.
|
||
|
||
|
||

v0.48.2 "argonaut"
|
||
==================
|
||
|
||
Upgrading
|
||
---------
|
||
|
||

|
||
|
||
* The ceph-disk-prepare and ceph-disk-active scripts have been updated significantly. These have not been previously documented or recommended. Any existing users should review the changes before upgrading.

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)
|
||
* rbd: fix perf stats for cache hit rate
|
||
* rbd tool: fix off-by-one in key name (crash when empty key specified)
|
||
* rbd: more robust udev rules
|
||
* rados tool: copy object, pool commands
|
||
* radosgw: fix in usage stats trimming
|
||
* radosgw: misc API compatibility fixes (date strings, ETag quoting, swift headers, etc.)
|
||
* ceph-fuse: fix locking in read/write paths
|
||
* mon: fix rare race corrupting on-disk data
|
||
* config: fix admin socket 'config set' command
|
||
* log: fix in-memory log event gathering
|
||
* debian: remove crush headers, include librados-config
|
||
* rpm: add ceph-disk-{activate, prepare}

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.
