ceph/PendingReleaseNotes

   1 >= 12.1.2
   2 ---------
   3 * When running 'df' on a CephFS filesystem comprising exactly one data pool,
   4   the result now reflects the file storage space used and available in that
   5   data pool (fuse client only).
   6 * Added new commands "pg force-recovery" and "pg-force-backfill". Use them
   7   to boost recovery or backfill priority of specified pgs, so they're
   8   recovered/backfilled before any other. Note that these commands don't
   9   interrupt ongoing recovery/backfill, but merely queue specified pgs
  10   before others so they're recovered/backfilled as soon as possible.
  11   New commands "pg cancel-force-recovery" and "pg cancel-force-backfill"
  12   restore default recovery/backfill priority of previously forced pgs.

  15 12.2.1
  16 ------
  17
  18 * Clusters will need to upgrade to 12.2.1 before upgrading to any
  19   Mimic 13.y.z version (either a development release or an eventual
  20   stable Mimic release).

  22 - *CephFS*:
  23
  24   * Limiting MDS cache via a memory limit is now supported using the new
  25     mds_cache_memory_limit config option (1GB by default).  A cache reservation
  26     can also be specified using mds_cache_reservation as a percentage of the
  27     limit (5% by default). Limits by inode count are still supported using
  28     mds_cache_size. Setting mds_cache_size to 0 (the default) disables the
  29     inode limit.
