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.

Hi All,
This is a new release of ceph-deploy that includes a new feature for
Hammer and bugfixes. ceph-deploy can be installed from the ceph.com
hosted repos for Firefly, Giant, Hammer, or testing, and is also
available on PyPI.
ceph-deploy now defaults to installing the Hammer release. If you need
to install a different release, use the --release flag.
To go along with the Hammer release, ceph-deploy now includes support
for a drastically simplified deployment for RGW. See further details
at [1] and [2].
This release also fixes an issue where keyrings pushed to remote nodes
ended up with world-readable permissions.
The full changelog can be seen at [3].
Please update!
Cheers,
- Travis

This major release is expected to form the basis of the next long-term
stable series. It is intended to supercede 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:
http://ceph.com/docs/master/start/quick-ceph-deploy/#add-an-rgw-instance
* 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.
* RADOS cache tiering: A series of changes have been made in the
cache tiering code that improve performance and reduce latency.
* Experimental 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.
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,
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
* Firefly to 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.

Getting Ceph
------------
* Git at git://github.com/ceph/ceph.git

* For packages, see http://ceph.com/docs/master/install/get-packages
* For ceph-deploy, see http://ceph.com/docs/master/install/install-ceph-deploy
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
http://docs.ceph.com/docs/master/_downloads/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.

Hi All,
This is a new release of ceph-deploy that changes a couple of behaviors.
On RPM-based distros, ceph-deploy will now automatically enable
check_obsoletes in the Yum priorities plugin. This resolves an issue
many community members hit where package dependency resolution was
breaking due to conflicts between upstream packaging (hosted on
ceph.com) and downstream (i.e., Fedora or EPEL).
The other important change is that when using ceph-deploy to install
Ceph packages on a RHEL machine, the --release flag *must* be used if
you want to install upstream packages. In other words, if you want to
install Giant on a RHEL machine, you would need to use "ceph-deploy
install --release giant". If the --release flag is not used,
ceph-deploy will expect to use downstream package on RHEL. This is
documented at [1].
The full changelog can be seen at [2].
Please update!
- Travis
[1] http://ceph.com/ceph-deploy/docs/install.html#distribution-notes
[2] http://ceph.com/ceph-deploy/docs/changelog.html#id1
This is the first (and possibly final) point release for Giant. Our focus
on stability fixes will be directed towards Hammer and Firefly.
We recommend that all v0.87 Giant users upgrade to this release.

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.

* 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().
