Cuttlefish
|
|
==========
|
|
|
|
Cuttlefish is the 3rd stable release of Ceph. It is named after a type
|
|
of cephalopod (order Sepiida) characterized by a unique internal shell, the
|
|
cuttlebone, which is used for control of buoyancy.
|
|
|
|

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 recommend
|
|
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)
|

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

|
|
---------------
|
|
|
|
* mon: fix daemon exit behavior when error is encountered on startup
|
|
* mon: more robust sync behavior
|
|

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

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

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 ...')

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"

|
|
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).
|
|
|
|
* 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 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 currently 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 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 currently rely on these functions zapping
|
|
data without confirmation need to be adjusted accordingly.
|
|
