[Ceph-announce] v15.2.4 Octopus released

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 They have been replaced by a tool, currently considered experimental, `rgw-orphan-list`.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.
