>=16.0.0
|
|
--------
|
|
* 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-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.
|
|
|
|
>=15.0.0
|
|
--------
|
|
|
|
* The ``ceph df`` command now lists the number of pgs in each pool.
|
|
|
|
* Monitors now have config option ``mon_allow_pool_size_one``, which is disabled
|
|
by default. However, if enabled, user now have to pass the
|
|
``--yes-i-really-mean-it`` flag to ``osd pool set size 1``, if they are really
|
|
sure of configuring pool size 1.
|
|
|
|
* librbd now inherits the stripe unit and count from its parent image upon creation.
|
|
This can be overridden by specifying different stripe settings during clone creation.
|
|
|
|
* The balancer is now on by default in upmap mode. Since upmap mode requires
|
|
``require_min_compat_client`` luminous, new clusters will only support luminous
|
|
and newer clients by default. Existing clusters can enable upmap support by running
|
|
``ceph osd set-require-min-compat-client luminous``. It is still possible to turn
|
|
the balancer off using the ``ceph balancer off`` command. In earlier versions,
|
|
the balancer was included in the ``always_on_modules`` list, but needed to be
|
|
turned on explicitly using the ``ceph balancer on`` command.
|
|
|
|
* MGR: the "cloud" mode of the diskprediction module is not supported anymore
|
|
and the ``ceph-mgr-diskprediction-cloud`` manager module has been removed. This
|
|
is because the external cloud service run by ProphetStor is no longer accessible
|
|
and there is no immediate replacement for it at this time. The "local" prediction
|
|
mode will continue to be supported.
|
|
|
|
* 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``.
|
|
|
|
* CephFS: Automatic static subtree partitioning policies may now be configured
|
|
using the new distributed and random ephemeral pinning extended attributes on
|
|
directories. See the documentation for more information:
|
|
https://docs.ceph.com/docs/master/cephfs/multimds/
|
|
|
|
* 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.
|
|
|
|
* librbd: The shared, read-only parent cache has been moved to a separate librbd
|
|
plugin. If the parent cache was previously in-use, you must also instruct
|
|
librbd to load the plugin by adding the following to your configuration::
|
|
|
|
rbd_plugins = parent_cache
|
|
|
|
* Monitors now have a config option ``mon_osd_warn_num_repaired``, 10 by default.
|
|
If any OSD has repaired more than this many I/O errors in stored data a
|
|
``OSD_TOO_MANY_REPAIRS`` health warning is generated.
|
|
|
|
* Introduce commands that manipulate required client features of a file system::
|
|
|
|
ceph fs required_client_features <fs name> add <feature>
|
|
ceph fs required_client_features <fs name> rm <feature>
|
|
ceph fs feature ls
|
|
|
|
* OSD: A new configuration option ``osd_compact_on_start`` has been added which triggers
|
|
an OSD compaction on start. Setting this option to ``true`` and restarting an OSD
|
|
will result in an offline compaction of the OSD prior to booting.
|
|
|
|
* OSD: the option named ``bdev_nvme_retry_count`` has been removed. Because
|
|
in SPDK v20.07, there is no easy access to bdev_nvme options, and this
|
|
option is hardly used, so it was removed.
|
|
|
|
* Now when noscrub and/or nodeep-scrub flags are set globally or per pool,
|
|
scheduled scrubs of the type disabled will be aborted. All user initiated
|
|
scrubs are NOT interrupted.
|
|
|
|
* Alpine build related script, documentation and test have been removed since
|
|
the most updated APKBUILD script of Ceph is already included by Alpine Linux's
|
|
aports repository.
|
|
|
|
* fs: Names of new FSs, volumes, subvolumes and subvolume groups can only
|
|
contain alphanumeric and ``-``, ``_`` and ``.`` characters. Some commands
|
|
or CephX credentials may not work with old FSs with non-conformant names.
|
|
|
|
* `blacklist` has been replaced with `blocklist` throughout. The following commands have changed:
|
|
|
|
- ``ceph osd blacklist ...`` are now ``ceph osd blocklist ...``
|
|
- ``ceph <tell|daemon> osd.<NNN> dump_blacklist`` is now ``ceph <tell|daemon> osd.<NNN> dump_blocklist``
|
|
|
|
* The following config options have changed:
|
|
|
|
- ``mon osd blacklist default expire`` is now ``mon osd blocklist default expire``
|
|
- ``mon mds blacklist interval`` is now ``mon mds blocklist interval``
|
|
- ``mon mgr blacklist interval`` is now ''mon mgr blocklist interval``
|
|
- ``rbd blacklist on break lock`` is now ``rbd blocklist on break lock``
|
|
- ``rbd blacklist expire seconds`` is now ``rbd blocklist expire seconds``
|
|
- ``mds session blacklist on timeout`` is now ``mds session blocklist on timeout``
|
|
- ``mds session blacklist on evict`` is now ``mds session blocklist on evict``
|
|
|
|
* The following librados API calls have changed:
|
|
|
|
- ``rados_blacklist_add`` is now ``rados_blocklist_add``; the former will issue a deprecation warning and be removed in a future release.
|
|
- ``rados.blacklist_add`` is now ``rados.blocklist_add`` in the C++ API.
|
|
|
|
* The JSON output for the following commands now shows ``blocklist`` instead of ``blacklist``:
|
|
|
|
- ``ceph osd dump``
|
|
- ``ceph <tell|daemon> osd.<N> dump_blocklist``
|
|
|
|
* caps: MON and MDS caps can now be used to restrict client's ability to view
|
|
and operate on specific Ceph file systems. The FS can be specificed using
|
|
``fsname`` in caps. This also affects subcommand ``fs authorize``, the caps
|
|
produce by it will be specific to the FS name passed in its arguments.
|
|
|
|
* fs: "fs authorize" now sets MON cap to "allow <perm> fsname=<fsname>"
|
|
instead of setting it to "allow r" all the time.
|
|
|
|
* ``ceph pg #.# list_unfound`` output has been enhanced to provide
|
|
might_have_unfound information which indicates which OSDs may
|
|
contain the unfound objects.
