v0.87.1 Giant
|
|
=============
|
|
|
|
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.
|
|
|
|
Upgrading
|
|
---------
|
|
|
|
* 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.

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 gauge 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
|
|
* asynchronous 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 Benjamin 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 = ""
|
|
|

|
|
This is the second post-firefly development release. It includes a range
|

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.
