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.
I wonder if you can comment on upgrade policy for a mixed cluster - eg
where the majority is running 12.2.8 but a handful of newly-added osd
nodes were installed with 12.2.9. Should the 12.2.8 nodes be upgraded to
12.2.10 (this does sound like it should have no negative effects) and
just the 12.2.9 nodes kept to wait for a future release - or wait on all?
I'd suggest upgrading everything to 12.2.10. If you aren't hitting
crashes already with this mixed 12.2.9 + 12.2.8 cluster, a further
upgrade shouldn't cause any issues.
