v14.2.5 Nautilus

This is the fifth release of the Ceph Nautilus release series. Among the manynotable changes, this release fixes a critical BlueStore bug that was introducedin 14.2.3. All Nautilus users are advised to upgrade to this release.

Notable Changes

Critical fix:

  • This release fixes a critical BlueStore bugintroduced in 14.2.3 (and also present in 14.2.4) that can lead to datacorruption when a separate “WAL” device is used.

New health warnings:

  • Ceph will now issue health warnings if daemons have recently crashed. Cephhas been collecting crash reports since the initial Nautilus release, but thehealth alerts are new. To view new crashes (or all crashes, if you’ve justupgraded):
  1. ceph crash ls-new

To acknowledge a particular crash (or all crashes) and silence the health warning:

  1. ceph crash archive <crash-id>
  2. ceph crash archive-all
  • Ceph will now issue a health warning if a RADOS pool has a pg_numvalue that is not a power of two. This can be fixed by adjustingthe pool to a nearby power of two:
  1. ceph osd pool set <pool-name> pg_num <new-pg-num>

Alternatively, the warning can be silenced with:

  1. ceph config set global mon_warn_on_pool_pg_num_not_power_of_two false
  • Ceph will issue a health warning if a RADOS pool’s size is set to 1or, in other words, if the pool is configured with no redundancy. Ceph willstop issuing the warning if the pool size is set to the minimumrecommended value:
  1. ceph osd pool set <pool-name> size <num-replicas>

The warning can be silenced with:

  1. ceph config set global mon_warn_on_pool_no_redundancy false
  • A health warning is now generated if the average osd heartbeat pingtime exceeds a configurable threshold for any of the intervalscomputed. The OSD computes 1 minute, 5 minute and 15 minuteintervals with average, minimum and maximum values. New configurationoption mon_warn_on_slow_ping_ratio specifies a percentage ofosd_heartbeat_grace to determine the threshold. A value of zerodisables the warning. New configuration option mon_warn_on_slow_ping_time_specified in milliseconds over-rides the computed value, causes a warningwhen OSD heartbeat pings take longer than the specified amount.A new admin command, _ceph daemon mgr.# dump_osd_network [threshold], willlist all connections with a ping time longer than the specified threshold orvalue determined by the config options, for the average for any of the 3 intervals.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 reports more information.

First, there is a new ‘device’ channel, enabled by default, thatwill report anonymized hard disk and SSD health metrics totelemetry.ceph.com in order to build and improve device failureprediction algorithms. If you are not comfortable sharing devicemetrics, you can disable that channel first before re-opting-in:

  1. ceph config set mgr mgr/telemetry/channel_device false

Second, we now report 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, andwhich 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, howbig buckets are, how many rules are defined, and what tunables are inuse

If you had telemetry enabled, you will need to re-opt-in with:

  1. ceph telemetry on

You can view exactly what information will be reported first with:

  1. ceph telemetry show        # see everything
  2. ceph telemetry show basic  # basic cluster info (including all of the new info)

OSD:

  • A new OSD daemon command, ‘dump_recovery_reservations’, reveals therecovery locks held (in_progress) and waiting in priority queues.

  • Another new OSD daemon command, ‘dump_scrub_reservations’, reveals thescrub 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 forstoring 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
