Dumpling
|
|
========
|
|
|
|
Dumpling is the 4th stable release of Ceph. It is named after the
|
|
dumpling squid (Euprymna tasmanica).
|
|
|
|
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.
|
|
|
|

fixes a problem when upgrading directly from v0.56.x Bobtail to
|
|
v0.67.x Dumpling (without stopping at v0.61.x Cuttlefish along the
|
|
way). It also fixes a problem with the CLI parsing of the CEPH_ARGS
|
|
environment variable, high CPU utilization by the ceph-osd daemons,
|
|
and cleans up the radosgw shutdown sequence.
|
|
|
|
Notable Changes
|
|
---------------
|
|
|
|
* objecter: resend linger requests when cluster goes from full to non-full
|
|
* ceph: parse CEPH_ARGS environment variable
|
|
* librados: fix small memory leak
|
|
* osd: remove old log objects on upgrade (fixes bobtail -> dumpling jump)
|
|
* osd: disable PGLog::check() via config option (fixes CPU burn)
|
|
* rgw: drain requests on shutdown
|
|
* rgw: misc memory leaks on shutdown

v0.67.1 "Dumpling"
|
|
==================
|
|
|
|
This is a minor point release for Dumpling that fixes problems with
|
|
OpenStack and librbd hangs when caching is disabled.
|
|
|
|
Notable changes
|
|
---------------
|
|
|
|
* librados, librbd: fix constructor for python bindings with certain
|
|
usages (in particular, that used by OpenStack)
|
|
* librados, librbd: fix aio_flush wakeup when cache is disabled
|
|
* librados: fix locking for aio completion refcounting
|
|
* fixes 'ceph --admin-daemon ...' command error code on error
|
|
* fixes 'ceph daemon ... config set ...' command for boolean config
|
|
options.

v0.67 "Dumpling"
|
|
================
|
|
|
|
This is the fourth major release of Ceph, code-named "Dumpling." The
|
|
headline features for this release include:
|
|
|
|
* Multi-site support for radosgw. This includes the ability to set up
|
|
separate "regions" in the same or different Ceph clusters that share
|
|
a single S3/Swift bucket/container namespace.
|
|
|
|
* RESTful API endpoint for Ceph cluster administration.
|
|
ceph-rest-api, a wrapper around ceph_rest_api.py, can be used to
|
|
start up a test single-threaded HTTP server that provides access to
|
|
cluster information and administration in very similar ways to the
|
|
ceph commandline tool. ceph_rest_api.py can be used as a WSGI
|
|
application for deployment in a more-capable web server. See
|
|
ceph-rest-api.8 for more.
|
|
|
|
* Object namespaces in librados.

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 accommodate 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
|
|
overridable 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.

|
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 presence of any
|
|
pool in the cluster with the flag enabled will make the OSD require
|
|
support from all clients.

=====
|
|
|
|
Upgrading
|
|
---------
|
|
|
|
* 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
