v12.2.10 Luminous released

This is 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

OSD

  • This release reverts the PG hard-limit patches added in v12.2.9 (https://tracker.ceph.com/issues/23979), in which, a partial upgrade,  during  a recovery or a backfill can cause the osds on the previous version, to fail with assert(trim_to <= info.last_complete). The workaround for users running v12.2.9 is to upgrade and restart all OSDs to a version with the pg hard limit, or only upgrade when all PGs are active+clean.

        As mentioned in the release announcements if you have updated to v12.2.9 already, please do NOT upgrade to v12.2.10 until the above mentioned issue is addressed

  • 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
