+v14.2.8 Nautilus
+================
+
+This is the eighth update to the Ceph Nautilus release series. This release
+fixes issues across a range of subsystems. We recommend that all users upgrade
+to this release.
+
+Notable Changes
+---------------
+
+* The default value of ``bluestore_min_alloc_size_ssd`` has been changed to 4K to improve performance across all workloads.
+
+* The following OSD memory config options related to bluestore cache autotuning can now
+ be configured during runtime:
+
+ - osd_memory_base (default: 768 MB)
+ - osd_memory_cache_min (default: 128 MB)
+ - osd_memory_expected_fragmentation (default: 0.15)
+ - osd_memory_target (default: 4 GB)
+
+ The above options can be set with::
+
+ ceph config set osd <option> <value>
+
+* The MGR now accepts ``profile rbd`` and ``profile rbd-read-only`` user caps.
+ These caps can be used to provide users access to MGR-based RBD functionality
+ such as ``rbd perf image iostat`` an ``rbd perf image iotop``.
+
+* The configuration value ``osd_calc_pg_upmaps_max_stddev`` used for upmap
+ balancing has been removed. Instead use the mgr balancer config
+ ``upmap_max_deviation`` which now is an integer number of PGs of deviation
+ from the target PGs per OSD. This can be set with a command like
+ ``ceph config set mgr mgr/balancer/upmap_max_deviation 2``. The default
+ ``upmap_max_deviation`` is 5. There are situations where crush rules
+ would not allow a pool to ever have completely balanced PGs. For example, if
+ crush requires 1 replica on each of 3 racks, but there are fewer OSDs in 1 of
+ the racks. In those cases, the configuration value can be increased.
+
+* RGW: a mismatch between the bucket notification documentation and the actual
+ message format was fixed. This means that any endpoints receiving bucket
+ notification, will now receive the same notifications inside a JSON array
+ named 'Records'. Note that this does not affect pulling bucket notification
+ from a subscription in a 'pubsub' zone, as these are already wrapped inside
+ that array.
+
+* CephFS: multiple active MDS forward scrub is now rejected. Scrub currently
+ only is permitted on a file system with a single rank. Reduce the ranks to one
+ via ``ceph fs set <fs_name> max_mds 1``.
+
+* Ceph now refuses to create a file system with a default EC data pool. For
+ further explanation, see:
+ https://docs.ceph.com/docs/nautilus/cephfs/createfs/#creating-pools
+
+* Ceph will now issue a health warning if a RADOS pool has a ``pg_num``
+ value that is not a power of two. This can be fixed by adjusting
+ the pool to a nearby power of two::
+
+ ceph osd pool set <pool-name> pg_num <new-pg-num>
+
+ Alternatively, the warning can be silenced with::
+
+ ceph config set global mon_warn_on_pool_pg_num_not_power_of_two false
+

ceph crash archive <crash-id>
ceph crash archive-all
-* Ceph will now issue a health warning if a RADOS pool has a ``pg_num``
- value that is not a power of two. This can be fixed by adjusting
- the pool to a nearby power of two::
-
- ceph osd pool set <pool-name> pg_num <new-pg-num>
-
- Alternatively, the warning can be silenced with::
-
- ceph config set global mon_warn_on_pool_pg_num_not_power_of_two false
-
* Ceph will issue a health warning if a RADOS pool's ``size`` is set to 1
or, in other words, if the pool is configured with no redundancy. Ceph will
stop issuing the warning if the pool size is set to the minimum
