We're happy to announce the fourth bugfix release in the Octopus series.
In addition to a security fix in RGW, this release brings a range of fixes
across all components. We recommend that all Octopus users upgrade to this
release. For a detailed release notes with links & changelog please
refer to the official blog entry at https://ceph.io/releases/v15-2-4-octopus-released
Notable Changes
---------------
* CVE-2020-10753: rgw: sanitize newlines in s3 CORSConfiguration's ExposeHeader
(William Bowling, Adam Mohammed, Casey Bodley)
* Cephadm: There were a lot of small usability improvements and bug fixes:
* Grafana when deployed by Cephadm now binds to all network interfaces.
* `cephadm check-host` now prints all detected problems at once.
* Cephadm now calls `ceph dashboard set-grafana-api-ssl-verify false`
when generating an SSL certificate for Grafana.
* The Alertmanager is now correctly pointed to the Ceph Dashboard
* `cephadm adopt` now supports adopting an Alertmanager
* `ceph orch ps` now supports filtering by service name
* `ceph orch host ls` now marks hosts as offline, if they are not
accessible.
* Cephadm can now deploy NFS Ganesha services. For example, to deploy NFS with
a service id of mynfs, that will use the RADOS pool nfs-ganesha and namespace
nfs-ns::
ceph orch apply nfs mynfs nfs-ganesha nfs-ns
* Cephadm: `ceph orch ls --export` now returns all service specifications in
yaml representation that is consumable by `ceph orch apply`. In addition,
the commands `orch ps` and `orch ls` now support `--format yaml` and
`--format json-pretty`.
* Cephadm: `ceph orch apply osd` supports a `--preview` flag that prints a preview of
the OSD specification before deploying OSDs. This makes it possible to
verify that the specification is correct, before applying it.
* RGW: The `radosgw-admin` sub-commands dealing with orphans --
`radosgw-admin orphans find`, `radosgw-admin orphans finish`, and
`radosgw-admin orphans list-jobs` -- have been deprecated. They have
not been actively maintained and they store intermediate results on
the cluster, which could fill a nearly-full cluster. They have been
replaced by a tool, currently considered experimental,
`rgw-orphan-list`.
* RBD: The name of the rbd pool object that is used to store
rbd trash purge schedule is changed from "rbd_trash_trash_purge_schedule"
to "rbd_trash_purge_schedule". Users that have already started using
`rbd trash purge schedule` functionality and have per pool or namespace
schedules configured should copy "rbd_trash_trash_purge_schedule"
object to "rbd_trash_purge_schedule" before the upgrade and remove
"rbd_trash_purge_schedule" using the following commands in every RBD
pool and namespace where a trash purge schedule was previously
configured::
rados -p <pool-name> [-N namespace] cp rbd_trash_trash_purge_schedule rbd_trash_purge_schedule
rados -p <pool-name> [-N namespace] rm rbd_trash_trash_purge_schedule
or use any other convenient way to restore the schedule after the
upgrade.

We're happy to announce the tenth release in the Nautilus series. In
addition to fixing a security-related bug in RGW, this release brings a
number of bugfixes across all major components of Ceph. We recommend
that all Nautilus users upgrade to this release. For a detailed
changelog please refer to the ceph release blog at:

Notable Changes
---------------
* CVE-2020-10753: rgw: sanitize newlines in s3 CORSConfiguration's ExposeHeader
(William Bowling, Adam Mohammed, Casey Bodley)
* RGW: Bucket notifications now support Kafka endpoints. This requires librdkafka of
version 0.9.2 and up. Note that Ubuntu 16.04.6 LTS (Xenial Xerus) has an older
version of librdkafka, and would require an update to the library.
* The pool parameter `target_size_ratio`, used by the pg autoscaler,
has changed meaning. It is now normalized across pools, rather than
specifying an absolute ratio. For details, see :ref:`pg-autoscaler`.
If you have set target size ratios on any pools, you may want to set
these pools to autoscale `warn` mode to avoid data movement during
the upgrade::
ceph osd pool set <pool-name> pg_autoscale_mode warn
* The behaviour of the `-o` argument to the rados tool has been reverted to
its orignal behaviour of indicating an output file. This reverts it to a more
consistent behaviour when compared to other tools. Specifying object size is now
accomplished by using an upper case O `-O`.
* The format of MDSs in `ceph fs dump` has changed.
* Ceph will issue a health warning if a RADOS pool's `size` is set to 1
or in other words the pool is configured with no redundancy. This can
be fixed by setting the pool size to the minimum recommended value
with::
ceph osd pool set <pool-name> size <num-replicas>
The warning can be silenced with::
ceph config set global mon_warn_on_pool_no_redundancy false
* RGW: bucket listing performance on sharded bucket indexes has been
notably improved by heuristically -- and significantly, in many
cases -- reducing the number of entries requested from each bucket
index shard.
