Bug description:
  [Impact]
  This release sports mostly bug-fixes and we would like to make sure all of our supported customers have access to these improvements.

  The update contains the following package updates:

     * ceph 12.2.7

  [Test Case]
  The following SRU process was followed:

  https://wiki.ubuntu.com/OpenStackUpdates

  In order to avoid regression of existing consumers, the OpenStack team
  will run their continuous integration test against the packages that
  are in -proposed. A successful run of all available tests will be
  required before the proposed packages can be let into -updates.

  The OpenStack team will be in charge of attaching the output summary
  of the executed tests. The OpenStack team members will not mark
  ‘verification-done’ until this has happened.

  [Regression Potential]
  In order to mitigate the regression potential, the results of the
  aforementioned tests are attached to this bug.

  [Original Bug Report]

  Hi
  I noticed the new ceph 12.2.7 release and no bug for it so here is a draft for it.

  Notes and changelog.
  https://ceph.com/releases/v12-2-7-luminous-released/

  [Impact]
  New upstream point release 12.2.7
  This is the fifth bugfix release of Luminous v12.2.x long term stable release series. This release contains a range of bug fixes across all compoenents of Ceph. We recommend all the users of 12.2.x series to update.

  [Test Case]
  See the changelog with individual bugs with numbers and links to them where available.

  [Regression Potential]
  Note again from previous released version 12.2.3:

  If someone update and restart any MDS (jewel or luminous before 12.2.3 to 12.2.3 or later, then all MDS's not yet running the new version and not aware of feature bit 9 will suicide.
  Operators may ignore the error messages and continue upgrading/restarting or follow this upgrade sequence to avoid it:

  Reduce the number of ranks to 1 (ceph fs set <fs_name> max_mds 1),
  wait for all other MDS to deactivate, leaving the one active MDS,
  upgrade the single active MDS, then upgrade/start standbys.
  Finally,restore the previous max_mds.

  Need good testing to make sure it is correct and stable, compared with
  previous version, before moving forward.

  Running earlier versions cause a higher risk to encounter an issue
  that have already been corrected.

  [Discussion]
  Please correct this description when needed. Also thanks to all that are working on this.
