------
- * Ceph will now issue a health warning if a RADOS pool as a ``pg_num``
- value that is not a power of two. This can be fixed by adjusting
- the pool to a nearby power of two::
-
- ceph osd pool set <pool-name> pg_num <new-pg-num>
-
- Alternatively, the warning can be silenced with::
-
- ceph config set global mon_warn_on_pool_pg_num_not_power_of_two false
-
- 14.2.4
- ------
-
- * In the Zabbix Mgr Module there was a typo in the key being send
- to Zabbix for PGs in backfill_wait state. The key that was sent
- was 'wait_backfill' and the correct name is 'backfill_wait'.
- Update your Zabbix template accordingly so that it accepts the
- new key being send to Zabbix.
-
- 14.2.3
- ------
-
- * Nautilus-based librbd clients can now open images on Jewel clusters.
-
- * The RGW "num_rados_handles" has been removed.
- If you were using a value of "num_rados_handles" greater than 1
- multiply your current "objecter_inflight_ops" and
- "objecter_inflight_op_bytes" paramaeters by the old
- "num_rados_handles" to get the same throttle behavior.
-
- * The ``bluestore_no_per_pool_stats_tolerance`` config option has been
- replaced with ``bluestore_fsck_error_on_no_per_pool_stats``
- (default: false). The overall default behavior has not changed:
- fsck will warn but not fail on legacy stores, and repair will
- convert to per-pool stats.
-
-
- 14.2.2
- ------
-
- * The no{up,down,in,out} related commands has been revamped.
- There are now 2 ways to set the no{up,down,in,out} flags:
- the old 'ceph osd [un]set <flag>' command, which sets cluster-wide flags;
- and the new 'ceph osd [un]set-group <flags> <who>' command,
- which sets flags in batch at the granularity of any crush node,
- or device class.
-
- * RGW: radosgw-admin introduces two subcommands that allow the
- managing of expire-stale objects that might be left behind after a
- bucket reshard in earlier versions of RGW. One subcommand lists such
- objects and the other deletes them. Read the troubleshooting section
- of the dynamic resharding docs for details.
-
- 14.2.5
- ------
-
- * The telemetry module now has a 'device' channel, enabled by default, that
- will report anonymized hard disk and SSD health metrics to telemetry.ceph.com
- in order to build and improve device failure prediction algorithms. Because
- the content of telemetry reports has changed, you will need to either re-opt-in
- with::
-
- ceph telemetry on
-
- You can view exactly what information will be reported first with::
-
- ceph telemetry show
- ceph telemetry show device # specifically show the device channel
-
- If you are not comfortable sharing device metrics, you can disable that
- channel first before re-opting-in:
-
- ceph config set mgr mgr/telemetry/channel_crash false
- ceph telemetry on
-
- * The telemetry module now reports more information about CephFS file systems,
- including:
-
- - how many MDS daemons (in total and per file system)
- - which features are (or have been) enabled
- - how many data pools
- - approximate file system age (year + month of creation)
- - how many files, bytes, and snapshots
- - how much metadata is being cached
-
- We have also added:
-
- - which Ceph release the monitors are running
- - whether msgr v1 or v2 addresses are used for the monitors
- - whether IPv4 or IPv6 addresses are used for the monitors
- - whether RADOS cache tiering is enabled (and which mode)
- - whether pools are replicated or erasure coded, and
- which erasure code profile plugin and parameters are in use
- - how many hosts are in the cluster, and how many hosts have each type of daemon
- - whether a separate OSD cluster network is being used
- - how many RBD pools and images are in the cluster, and how many pools have RBD mirroring enabled
- - how many RGW daemons, zones, and zonegroups are present; which RGW frontends are in use
- - aggregate stats about the CRUSH map, like which algorithms are used, how big buckets are, how many rules are defined, and what tunables are in use
-
- If you had telemetry enabled, you will need to re-opt-in with::
-
- ceph telemetry on
-
- You can view exactly what information will be reported first with::
-
- ceph telemetry show # see everything
- ceph telemetry show basic # basic cluster info (including all of the new info)
-
- * A health warning is now generated if the average osd heartbeat ping
- time exceeds a configurable threshold for any of the intervals
- computed. The OSD computes 1 minute, 5 minute and 15 minute
- intervals with average, minimum and maximum values. New configuration
- option ``mon_warn_on_slow_ping_ratio`` specifies a percentage of
- ``osd_heartbeat_grace`` to determine the threshold. A value of zero
- disables the warning. New configuration option
- ``mon_warn_on_slow_ping_time`` specified in milliseconds over-rides the
- computed value, causes a warning
- when OSD heartbeat pings take longer than the specified amount.
- New admin command ``ceph daemon mgr.# dump_osd_network [threshold]`` command will
- list all connections with a ping time longer than the specified threshold or
- value determined by the config options, for the average for any of the 3 intervals.
- New admin command ``ceph daemon osd.# dump_osd_network [threshold]`` will
- do the same but only including heartbeats initiated by the specified OSD.
-
- * New OSD daemon command dump_recovery_reservations which reveals the
- recovery locks held (in_progress) and waiting in priority queues.
-
- * New OSD daemon command dump_scrub_reservations which reveals the
- scrub reservations that are held for local (primary) and remote (replica) PGs.
-
- 14.2.6
- ------
-
* The following OSD memory config options related to bluestore cache autotuning can now
be configured during runtime:
would not allow a pool to ever have completely balanced PGs. For example, if
crush requires 1 replica on each of 3 racks, but there are fewer OSDs in 1 of
the racks. In those cases, the configuration value can be increased.
+
+ * RGW: a mismatch between the bucket notification documentation and the actual
+ message format was fixed. This means that any endpoints receiving bucket
+ notification, will now receive the same notifications inside an JSON array
+ named 'Records'. Note that this does not affect pulling bucket notification
+ from a subscription in a 'pubsub' zone, as these are already wrapped inside
+ that array.
++
++* Ceph will now issue a health warning if a RADOS pool as a ``pg_num``
++ value that is not a power of two. This can be fixed by adjusting
++ the pool to a nearby power of two::
++
++ ceph osd pool set <pool-name> pg_num <new-pg-num>
++
++ Alternatively, the warning can be silenced with::
++
++ ceph config set global mon_warn_on_pool_pg_num_not_power_of_two false
