We're happy to announce the 4th backport release in the Quincy series. We recommend users to update to this release. For detailed release notes with links & changelog please refer to the official blog entry at https://ceph.io/en/news/blog/2022/v17-2-4-quincy-released/ Notable Changes --------------- * Cephfs: The 'AT_NO_ATTR_SYNC' macro is deprecated, please use the standard 'AT_STATX_DONT_SYNC' macro. The 'AT_NO_ATTR_SYNC' macro will be removed in the future. * OSD: The issue of high CPU utilization during recovery/backfill operations has been fixed. For more details, see: https://tracker.ceph.com/issues/56530. * Trimming of PGLog dups is now controlled by the size instead of the version. This fixes the PGLog inflation issue that was happening when the on-line (in OSD) trimming got jammed after a PG split operation. Also, a new off-line mechanism has been added: `ceph-objectstore-tool` got `trim-pg-log-dups` op that targets situations where OSD is unable to boot due to those inflated dups. If that is the case, in OSD logs the "You can be hit by THE DUPS BUG" warning will be visible. Relevant tracker: https://tracker.ceph.com/issues/53729 * OSD: Octopus modified the SnapMapper key format from ``<LEGACY_MAPPING_PREFIX><snapid>_<shardid>_<hobject_t::to_str()>`` to ``<MAPPING_PREFIX><pool>_<snapid>_<shardid>_<hobject_t::to_str()>``. When this change was introduced, `94ebe0e <https://github.com/ceph/ceph/commit/94ebe0eab968068c29fdffa1bfe68c72122db633>`_ also introduced a conversion with a crucial bug which essentially destroyed legacy keys by mapping them to ``<MAPPING_PREFIX><poolid>_<snapid>_`` without the object-unique suffix. The conversion is fixed in this release.
