[Ceph-announce] v12.2.11 Luminous released

We are glad to announce the eleventh bug fix release of the Luminous v12.2.x long term stable release series. We recommend that all users upgrade to this release. Please note the following precautions while upgrading. Notable Changes --------------- * This release fixes the pg log hard limit bug that was introduced in 12.2.9, https://tracker.ceph.com/issues/36686. A flag called `pglog_hardlimit` has been introduced, which is off by default. Enabling this flag will limit the length of the pg log. In order to enable that, the flag must be set by running `ceph osd set pglog_hardlimit` after completely upgrading to 12.2.11. Once the cluster has this flag set, the length of the pg log will be capped by a hard limit. Once set, this flag *must not* be unset anymore. * There have been fixes to RGW dynamic and manual resharding, which no longer leaves behind stale bucket instances to be removed manually. For finding and cleaning up older instances from a reshard a radosgw-admin command `reshard stale-instances list` and `reshard stale-instances rm` should do the necessary cleanup.
