v12.2.13 Luminous released

This is the 13th bug fix release of the Luminous v12.2.x long term stable
release series. We recommend that all users upgrade to this release.

Notable Changes

  • Ceph now packages python bindings for python3.6 instead of
    python3.4, because EPEL7 recently switched from python3.4 to
    python3.6 as the native python3. see the announcement 
    for more details on the background of this change.
  • We now have telemetry support via a ceph-mgr module. The telemetry module is
    absolutely on an opt-in basis, and is meant to collect generic cluster
    information and push it to a central endpoint. By default, we’re pushing it
    to a project endpoint at https://telemetry.ceph.com/report, but this is
    customizable using by setting the ‘url’ config option with:

    ceph telemetry config-set url '<your url>'
    

    You will have to opt-in on sharing your information with:

    ceph telemetry on
    

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

    ceph telemetry show
    

    Should you opt-in, your information will be licensed under the
    Community Data License Agreement – Sharing – Version 1.0, which you can
    read at https://cdla.io/sharing-1-0/

    The telemetry module reports 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 much metadata is being cached per file system

    As well as:

    • 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 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
  • 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.
  • The configuration value osd_calc_pg_upmaps_max_stddev used for upmap
    balancing has been removed. Instead use the mgr balancer config
    upmap_max_deviation which now is an integer number of PGs of deviation
    from the target PGs per OSD. This can be set with a command like
    ceph config set mgr mgr/balancer/upmap_max_deviation 2. The default
    upmap_max_deviation is 1. There are situations where crush rules
    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.
