v14.2.5 Nautilus released
This is the fifth release of the Ceph Nautilus release series. Among the many notable changes, this release fixes a critical BlueStore bug that was introduced in 14.2.3. All Nautilus users are advised to upgrade to this release. For the complete changelog entry, please visit the release blog at https://ceph.io/releases/v14-2-5-nautilus-released/ Notable Changes --------------- Critical fix: * This release fixes a `critical BlueStore bug <https://tracker.ceph.com/issues/42223>`_ introduced in 14.2.3 (and also present in 14.2.4) that can lead to data corruption when a separate "WAL" device is used.

To view new crashes (or all crashes, if you've just upgraded):: ceph crash ls-new To acknowledge a particular crash (or all crashes) and silence the health warning:: ceph crash archive <crash-id> ceph crash archive-all * Ceph will now issue a health warning if a RADOS pool has a ``pg_num`` value that is not a power of two.

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.

A new admin command, `ceph daemon mgr.# dump_osd_network [threshold]`, will list all connections with a ping time longer than the specified
value determined by the config options, for the average for any of
Another new admin command, `ceph daemon osd.# dump_osd_network [threshold]`, will do the same but only including heartbeats initiated by the specified OSD.
Changes in the telemetry module:
* The telemetry module now has a 'device' channel, enabled by default,
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 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
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
- 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

OSD:
* A new OSD daemon command, 'dump_recovery_reservations', reveals the recovery locks held (in_progress) and waiting in priority queues.
* Another new OSD daemon command, 'dump_scrub_reservations', reveals the scrub reservations that are held for local (primary) and remote
(replica) PGs.
RGW:
* RGW now supports S3 Object Lock set of APIs allowing for a WORM model
for
storing objects. 6 new APIs have been added put/get bucket object lock, put/get object retention, put/get object legal hold.
* RGW now supports List Objects V2
