Luminous v12.2.10 released

Luminous v12.2.10 released

[Abhishek Lekshmanan]

We're happy to announce the tenth bug fix release of the Luminous
v12.2.x long term stable release series. The previous release, v12.2.9,
introduced the PG hard-limit patches which were found to cause an issue
in certain upgrade scenarios, and this release was expedited to revert
those patches. If you already successfully upgraded to v12.2.9, you
should **not** upgrade to v12.2.10, but rather **wait** for a release in
which http://tracker.ceph.com/issues/36686 is addressed. All other users
are encouraged to upgrade to this release.

Notable Changes
---------------

* This release reverts the PG hard-limit patches added in v12.2.9 in which,
  a partial upgrade during a recovery/backfill, can cause the osds on the
  previous version, to fail with assert(trim_to <= info.last_complete). The
  workaround for users is to upgrade and restart all OSDs to a version with the
  pg hard limit, or only upgrade when all PGs are active+clean.

  See also: http://tracker.ceph.com/issues/36686

  As mentioned above if you've successfully upgraded to v12.2.9 DO NOT
  upgrade to v12.2.10 until the linked tracker issue has been fixed.

* The bluestore_cache_* options are no longer needed. They are replaced
  by osd_memory_target, defaulting to 4GB. BlueStore will expand
  and contract its cache to attempt to stay within this
  limit. Users upgrading should note this is a higher default
  than the previous bluestore_cache_size of 1GB, so OSDs using
  BlueStore will use more memory by default.

  For more details, see BlueStore docs[1]

Re: Luminous v12.2.10 released

[Dan van der Ster]

Hey Abhishek,

We just noticed that the debuginfo is missing for 12.2.10:
http://download.ceph.com/rpm-luminous/el7/x86_64/ceph-debuginfo-12.2.10-0.el7.x86_64.rpm

Did something break in the publishing?

Cheers, Dan

Hey Dan,

Thanks for bringing this to our attention.  Looks like it did get left
out.  I just pushed the package and added a step to the release process
to make sure packages don't get skipped again like that.
