v0.64
-----
2013-06-13 17:19:39 +00:00
Upgrading
~~~~~~~~~
* New pools now have the HASHPSPOOL flag set by default to provide
better distribution over OSDs. Support for this feature was
introduced in v0.59 and Linux kernel version v3.9. If you wish to
access the cluster from an older kernel, set the 'osd pool default
flag hashpspool = false' option in your ceph.conf prior to creating
the cluster or creating new pools. Note that the presense of any
pool in the cluster with the flag enabled will make the OSD require
support from all clients.

-----
2013-06-13 17:19:39 +00:00
Upgrading
~~~~~~~~~

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.

v0.61.3 "Cuttlefish"
--------------------
This release resolves a number of problems with the monitors and leveldb that users have
been seeing. Please upgrade.
Upgrading
~~~~~~~~~
* There is one known problem with mon upgrades from bobtail. If the
ceph-mon conversion on startup is aborted or fails for some reason, we
do not correctly error out, but instead continue with (in certain cases)
odd results. Please be careful if you have to restart the mons during
the upgrade. A 0.61.4 release with a fix will be out shortly.
* In the meantime, for current cuttlefish users, v0.61.3 is safe to use.
Notable Changes
~~~~~~~~~~~~~~~
* mon: paxos state trimming fix (resolves runaway disk usage)
* mon: finer-grained compaction on trim
* mon: discard messages from disconnected clients (lowers load)
* mon: leveldb compaction and other stats available via admin socket
* mon: async compaction (lower overhead)
* mon: fix bug incorrectly marking osds down with insufficient failure reports
* osd: fixed small bug in pg request map
* osd: avoid rewriting pg info on every osdmap
* osd: avoid internal heartbeta timeouts when scrubbing very large objects
* osd: fix narrow race with journal replay
* mon: fixed narrow pg split race
* rgw: fix leaked space when copying object
* rgw: fix iteration over large/untrimmed usage logs
* rgw: fix locking issue with ops log socket
* rgw: require matching version of librados
* librbd: make image creation defaults configurable (e.g., create format 2 images via qemu-img)
* fix units in 'ceph df' output
* debian: fix prerm/postinst hooks to start/stop daemons appropriately
* upstart: allow uppercase daemons names (and thus hostnames)
* sysvinit: fix enumeration of local daemons by type
* sysvinit: fix osd weight calcuation when using -a
* fix build on unsigned char platforms (e.g., arm)
For more detailed information, see :download: `the complete changelog <changelog/v0.61.3.txt>` .
2013-05-14 03:48:20 +00:00
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>` .
2013-05-09 17:04:05 +00:00
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
2013-05-10 21:39:23 +00:00

v0.61 "Cuttlefish"
------------------
2013-04-30 23:42:23 +00:00
Upgrading from v0.60
~~~~~~~~~~~~~~~~~~~~
2013-04-24 23:41:50 +00:00
2013-05-02 14:30:36 +00:00
* 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`_ .
2013-05-03 18:36:37 +00:00
* 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 `` .
2013-04-24 23:41:50 +00:00
* 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
2013-05-10 21:39:23 +00:00
command and the 'rgw zone root pool' config options have changed
2013-04-24 23:41:50 +00:00
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.
2013-04-25 18:17:08 +00:00
* 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'
2013-05-10 21:39:23 +00:00
is used in conjunction with '-c path', the path must also be present
2013-04-25 18:17:08 +00:00
on the remote host (it is not copied to a temporary file, as it was
previously).
2013-04-30 23:42:23 +00:00
Upgrading from v0.56.4 "Bobtail"

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

v0.58
-----
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.
Notable Changes
~~~~~~~~~~~~~~~
* osd: default to libaio for the journal (some performance boost)
* osd: validate snap collections on startup
* osd: ceph-filestore-dump tool for debugging
* osd: deep-scrub omap keys/values

* mon: safety check for pool deletion
* mon: new checks for identifying and reporting clock drift
* radosgw: misc fixes
* rbd: wait for udev to settle in strategic places (avoid spurious errors, failures)
* rbd-fuse: new tool, package
* mds, ceph-fuse: manage layouts via xattrs
* mds: misc bug fixes with clustered MDSs and failure recovery
* mds: misc bug fixes with readdir
* libcephfs: many fixes, cleanups with the Java bindings
* auth: ability to require new cephx signatures on messages (still off by default)

v0.56.5 "bobtail"
-----------------
Upgrading
~~~~~~~~~
* ceph-disk[-prepare,-activate] behavior has changed in various ways.
There should not be any compatibility issues, but chef users should
be aware.
Notable changes
~~~~~~~~~~~~~~~

v0.56.4 "bobtail"
-----------------
Upgrading
~~~~~~~~~
* There is a fix in the syntax for the output of 'ceph osd tree --format=json'.
2013-03-25 23:24:48 +00:00
* 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.
2013-03-25 23:09:24 +00:00

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.
2013-02-18 05:10:52 +00:00
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.
2013-02-14 01:43:50 +00:00
Notable changes
~~~~~~~~~~~~~~~
* osd: flush peering work queue prior to start
* osd: persist osdmap epoch for idle PGs
* osd: fix and simplify connection handling for heartbeats
* osd: avoid crash on invalid admin command
* mon: fix rare races with monitor elections and commands
* mon: enforce that OSD reweights be between 0 and 1 (NOTE: not CRUSH weights)
* mon: approximate client, recovery bandwidth logging
* radosgw: fixed some XML formatting to conform to Swift API inconsistency
* radosgw: fix usage accounting bug; add repair tool
* radosgw: make fallback URI configurable (necessary on some web servers)
* librbd: fix handling for interrupted 'unprotect' operations
* mds, ceph-fuse: allow file and directory layouts to be modified via virtual xattrs

v0.56.2 "bobtail"
-----------------
This release has a wide range of bug fixes, stability improvements, and some performance improvements. Please upgrade.
Upgrading
~~~~~~~~~
* The meaning of the 'osd scrub min interval' and 'osd scrub max
interval' has changed slightly. The min interval used to be
meaningless, while the max interval would only trigger a scrub if
the load was sufficiently low. Now, the min interval option works
the way the old max interval did (it will trigger a scrub after this
amount of time if the load is low), while the max interval will
force a scrub regardless of load. The default options have been
adjusted accordingly. If you have customized these in ceph.conf,
please review their values when upgrading.
* CRUSH maps that are generated by default when calling `` ceph-mon
--mkfs`` directly now distribute replicas across hosts instead of
across OSDs. Any provisioning tools that are being used by Ceph may
be affected, although probably for the better, as distributing across
hosts is a much more commonly sought behavior. If you use
`` mkcephfs `` to create the cluster, the default CRUSH rule is still
inferred by the number of hosts and/or racks in the initial ceph.conf.
Notable changes
~~~~~~~~~~~~~~~
* osd: snapshot trimming fixes
* osd: scrub snapshot metadata
* osd: fix osdmap trimming
* osd: misc peering fixes
* osd: stop heartbeating with peers if internal threads are stuck/hung
* osd: PG removal is friendlier to other workloads
* osd: fix recovery start delay (was causing very slow recovery)
* osd: fix scheduling of explicitly requested scrubs
* osd: fix scrub interval config options
* osd: improve recovery vs client io tuning
* osd: improve 'slow request' warning detail for better diagnosis
* osd: default CRUSH map now distributes across hosts, not OSDs
* osd: fix crash on 32-bit hosts triggered by librbd clients
* librbd: fix error handling when talking to older OSDs
* mon: fix a few rare crashes
* ceph command: ability to easily adjust CRUSH tunables
* radosgw: object copy does not copy source ACLs
* rados command: fix omap command usage
* sysvinit script: set ulimit -n properly on remote hosts
* msgr: fix narrow race with message queuing
* fixed compilation on some old distros (e.g., RHEL 5.x)

2013-01-08 04:46:31 +00:00
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

2012-12-15 00:56:24 +00:00
v0.56 "bobtail"
---------------
Bobtail is the second stable release of Ceph, named in honor of the
`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.
2012-12-21 23:08:47 +00:00
* RADOS Block Device (RBD): advisory image locking
2012-12-15 00:56:24 +00:00
* 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
~~~~~~~~~
2012-12-30 04:46:36 +00:00
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
2012-12-15 00:56:24 +00:00
* 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.
2012-12-28 06:08:05 +00:00
* 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
2012-12-17 22:39:15 +00:00
* You should not create or use "format 2" RBD images until after all
`` ceph-osd `` daemons have been upgraded. Note that "format 1" is
2012-12-20 23:08:11 +00:00
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
2012-12-17 22:39:15 +00:00
2012-12-15 00:56:24 +00:00
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.
2012-12-20 21:29:10 +00:00
* 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.
2012-12-21 23:08:47 +00:00
* 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.
2012-12-28 21:47:08 +00:00
* 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
2012-12-15 00:56:24 +00:00
* 'rbd lock list' and 'rbd showmapped' no longer use tabs as
separators in their output.
2012-12-17 18:53:25 +00:00
* 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).
2012-12-15 00:56:24 +00:00
* 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.
2012-12-21 23:08:47 +00:00
* '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
2012-12-15 00:56:24 +00:00

Upgrading
~~~~~~~~~
2012-11-14 00:24:23 +00:00
* 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.

v0.48.1 "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.
