We're happy to announce the 15th, and expected to be the last, backport release in the Pacific series. https://ceph.io/en/news/blog/2024/v16-2-15-pacific-released/ Notable Changes --------------- * `ceph config dump --format <json|xml>` output will display the localized option names instead of their normalized version. For example, "mgr/prometheus/x/server_port" will be displayed instead of "mgr/prometheus/server_port". This matches the output of the non pretty-print formatted version of the command. * CephFS: MDS evicts clients who are not advancing their request tids, which causes a large buildup of session metadata, resulting in the MDS going read-only due to the RADOS operation exceeding the size threshold. The `mds_session_metadata_threshold` config controls the maximum size that an (encoded) session metadata can grow. * RADOS: The `get_pool_is_selfmanaged_snaps_mode` C++ API has been deprecated due to its susceptibility to false negative results. Its safer replacement is `pool_is_in_selfmanaged_snaps_mode`. * RBD: When diffing against the beginning of time (`fromsnapname == NULL`) in fast-diff mode (`whole_object == true` with `fast-diff` image feature enabled and valid), diff-iterate is now guaranteed to execute locally if exclusive lock is available. This brings a dramatic performance improvement for QEMU live disk synchronization and backup use cases.
