* New bluestore_rocksdb_options_annex config parameter. Complements
bluestore_rocksdb_options and allows setting rocksdb options without repeating
the existing defaults.
-* The cephfs addes two new CDentry tags, 'I' --> 'i' and 'L' --> 'l', and
- on-RADOS metadata is no longer backwards compatible after upgraded to Pacific
- or a later release.
+* The MDS in Pacific makes backwards-incompatible changes to the ON-RADOS
+ metadata structures, which prevent a downgrade to older releases
+ (to Octopus and older).
* $pid expansion in config paths like `admin_socket` will now properly expand
to the daemon pid for commands like `ceph-mds` or `ceph-osd`. Previously only
* The allowable options for some "radosgw-admin" commands have been changed.
- * "mdlog-list", "datalog-list", "sync-error-list" no longer accepts
- start and end dates, but does accept a single optional start marker.
+ * "mdlog-list", "datalog-list", "sync-error-list" no longer accept
+ start and end dates, but do accept a single optional start marker.
* "mdlog-trim", "datalog-trim", "sync-error-trim" only accept a
single marker giving the end of the trimmed range.
* Similarly the date ranges and marker ranges have been removed on
the RESTful DATALog and MDLog list and trim operations.
-* ceph-volume: The ``lvm batch` subcommand received a major rewrite. This closed
- a number of bugs and improves usability in terms of size specification and
- calculation, as well as idempotency behaviour and disk replacement process.
- Please refer to https://docs.ceph.com/en/latest/ceph-volume/lvm/batch/ for
- more detailed information.

* Configuration variables for permitted scrub times have changed. The legal
- values for ``osd_scrub_begin_hour`` and ``osd_scrub_end_hour`` are 0 - 23.
- The use of 24 is now illegal. Specifying ``0`` for both values causes every
- hour to be allowed. The legal vaues for ``osd_scrub_begin_week_day`` and
- ``osd_scrub_end_week_day`` are 0 - 6. The use of 7 is now illegal.
- Specifying ``0`` for both values causes every day of the week to be allowed.
-
-* Multiple file systems in a single Ceph cluster is now stable. New Ceph clusters
- enable support for multiple file systems by default. Existing clusters
- must still set the "enable_multiple" flag on the fs. Please see the CephFS
- documentation for more information.
-
-* volume/nfs: Recently "ganesha-" prefix from cluster id and nfs-ganesha common
- config object was removed, to ensure consistent namespace across different
- orchestrator backends. Please delete any existing nfs-ganesha clusters prior

-* A new health check, DAEMON_OLD_VERSION, will warn if different versions of Ceph are running
- on daemons. It will generate a health error if multiple versions are detected.
- This condition must exist for over mon_warn_older_version_delay (set to 1 week by default) in order for the
- health condition to be triggered. This allows most upgrades to proceed
- without falsely seeing the warning. If upgrade is paused for an extended
- time period, health mute can be used like this
- "ceph health mute DAEMON_OLD_VERSION --sticky". In this case after
- upgrade has finished use "ceph health unmute DAEMON_OLD_VERSION".

-* MGR: progress module can now be turned on/off, using the commands:

-* An AWS-compliant API: "GetTopicAttributes" was added to replace the existing "GetTopic" API. The new API
- should be used to fetch information about topics used for bucket notifications.

- to property reflect the upper cache utilization before space is reclaimed. The default ``immutable_object_cache_watermark``
- now is ``0.9``. If the capacity reaches 90% the daemon will delete cold cache.
