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.
