Nautilus
========

Nautilus is the 14th stable release of Ceph.  It is named after the
nautilus, a family of cephalopods characterized by a whorled shell.

v14.2.22 Nautilus
=================

This is the 22nd and likely the last backport release in the Nautilus series.
Ultimately, we recommend all users upgrade to newer Ceph releases.

Notable Changes
---------------

* This release sets ``bluefs_buffered_io`` to true by default to improve performance
  for metadata heavy workloads. Enabling this option has been reported to
  occasionally cause excessive kernel swapping under certain workloads.
  Currently, the most consistent performing combination is to enable
  bluefs_buffered_io and disable system level swap.

* The default value of ``bluestore_cache_trim_max_skip_pinned`` has been
  increased to 1000 to control memory growth due to onodes.

* Several other bug fixes in BlueStore, including a fix for an unexpected
  ENOSPC bug in Avl/Hybrid allocators.

* The trimming logic in the monitor has been made dynamic, with the
  introduction of ``paxos_service_trim_max_multiplier``, a factor by which
  ``paxos_service_trim_max`` is multiplied to make trimming faster,
  when required. Setting it to 0 disables the upper bound check for trimming
  and makes the monitors trim at the maximum rate.

* A ``--max <n>`` option is available with the ``osd ok-to-stop`` command to
  provide up to N OSDs that can be stopped together without making PGs
  unavailable.

* OSD: the option ``osd_fast_shutdown_notify_mon`` has been introduced to allow
  the OSD to notify the monitor it is shutting down even if ``osd_fast_shutdown``
  is enabled. This helps with the monitor logs on larger clusters, that may get
  many 'osd.X reported immediately failed by osd.Y' messages, and confuse tools.

* A long-standing bug that prevented 32-bit and 64-bit client/server
  interoperability under msgr v2 has been fixed.  In particular, mixing armv7l
  (armhf) and x86_64 or aarch64 servers in the same cluster now works.

v14.2.21 Nautilus
=================

This is a hotfix release addressing a number of security issues and regressions. We recommend all users update to this release.

Changelog
---------

* mgr/dashboard: fix base-href: revert it to previous approach (`issue#50684 <https://tracker.ceph.com/issues/50684>`_, Avan Thakkar)
* mgr/dashboard: fix cookie injection issue (:ref:`CVE-2021-3509`, Ernesto Puerta)
* rgw: RGWSwiftWebsiteHandler::is_web_dir checks empty subdir_name (:ref:`CVE-2021-3531`, Felix Huettner)
* rgw: sanitize \r in s3 CORSConfiguration's ExposeHeader (:ref:`CVE-2021-3524`, Sergey Bobrov, Casey Bodley)


v14.2.20 Nautilus
=================

This is the 20th bugfix release in the Nautilus stable series.  It addresses a
security vulnerability in the Ceph authentication framework.

We recommend all Nautilus users upgrade.

Security fixes
--------------

* This release includes a security fix that ensures the global_id
  value (a numeric value that should be unique for every authenticated
  client or daemon in the cluster) is reclaimed after a network
  disconnect or ticket renewal in a secure fashion.  Two new health
  alerts may appear during the upgrade indicating that there are
  clients or daemons that are not yet patched with the appropriate
  fix.

  It is possible to disable the health alerts around insecure clients::

    ceph config set mon mon_warn_on_insecure_global_id_reclaim false
    ceph config set mon mon_warn_on_insecure_global_id_reclaim_allowed false

  However, if you disable these alerts, we strongly recommend that you
  follow up by removing these settings after clients have been
  upgraded or after upgrading to Octopus.  (Starting in Octopus, these
  health alerts can be muted for a specific period of time.)

  For more information, see :ref:`CVE-2021-20288`.


v14.2.19 Nautilus
=================

This is the 19th update to the Ceph Nautilus release series. This is a hotfix
release to prevent daemons from binding to loopback network interfaces. All

v14.2.17 Nautilus
=================

This is the 17th backport release in the Nautilus series. We recommend
users to update to this release.

Notable Changes
---------------

* $pid expansion in config paths like ``admin_socket`` will now properly expand
  to the daemon pid for commands like ``ceph-mds`` or ``ceph-osd``. Previously
  only ``ceph-fuse``/``rbd-nbd`` expanded ``$pid`` with the actual daemon pid.
* RADOS: PG removal has been optimized in this release.
* RADOS: Memory allocations are tracked in finer detail in BlueStore and displayed as a part of the ``dump_mempools`` command.
* cephfs: clients which acquire capabilities too quickly are throttled to prevent instability.  See new config option ``mds_session_cap_acquisition_throttle`` to control this behavior.

v14.2.12 Nautilus
=================

This is the 12th backport release in the Nautilus series. This release
brings a number of bugfixes across all major components of Ceph. We recommend
that all Nautilus users upgrade to this release.

Notable Changes
---------------

* The ``ceph df`` command now lists the number of pgs in each pool.

* 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.  In order to allow
  clearing of the warning, a new command ``ceph tell osd.# clear_shards_repaired [count]``
  has been added.  By default it will set the repair count to 0.  If you wanted
  to be warned again if additional repairs are performed you can provide a value
  to the command and specify the value of ``mon_osd_warn_num_repaired``.
  This command will be replaced in future releases by the health mute/unmute feature.

* It is now possible to specify the initial monitor to contact for Ceph tools
  and daemons using the ``mon_host_override`` config option or
  ``--mon-host-override <ip>`` command-line switch. This generally should only
  be used for debugging and only affects initial communication with Ceph's
  monitor cluster.

* Fix an issue with osdmaps not being trimmed in a healthy cluster (`issue#47296
  <https://tracker.ceph.com/issues/47296>`_, `pr#36982
  <https://github.com/ceph/ceph/pull/36982>`_)

v14.2.11 Nautilus
=================

This is the eleventh backport release in the Nautilus series. This release
brings a number of bugfixes across all major components of Ceph. We recommend
that all Nautilus users upgrade to this release.

Notable Changes
---------------

* RGW: The ``radosgw-admin`` sub-commands dealing with orphans --
  ``radosgw-admin orphans find``, ``radosgw-admin orphans finish``,
  ``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``.

* 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.

* Fixed a ceph-osd crash in _committed_osd_maps when there is a failure to encode
  the first incremental map. `issue#46443 <https://tracker.ceph.com/issues/46443>`_

v14.2.10 Nautilus
=================

This is 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.

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 original 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.

v14.2.9 Nautilus
================

This is the ninth bugfix release of Nautilus. This release fixes a
couple of security issues in RGW & Messenger V2. We recommend all users
to upgrade to this release.

Notable Changes
---------------

- CVE-2020-1759: Fixed nonce reuse in msgr V2 secure mode
- CVE-2020-1760: Fixed XSS due to RGW GetObject header-splitting

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

v14.2.7 Nautilus
================

This is the seventh update to the Ceph Nautilus release series. This is
a hotfix release primarily fixing a couple of security issues. We
recommend that all users upgrade to this release.

Notable Changes
---------------

* CVE-2020-1699: Fixed a path traversal flaw in Ceph dashboard that
  could allow for potential information disclosure (Ernesto Puerta)
* CVE-2020-1700: Fixed a flaw in RGW beast frontend that could lead to
  denial of service from an unauthenticated client (Or Friedmann)


v14.2.6 Nautilus
================

This is the sixth update to the Ceph Nautilus release series. This is a hotfix
release primarily fixing a regression introduced in v14.2.5, all nautilus users
are advised to upgrade to this release.

Notable Changes
---------------

* This release fixes a ``ceph-mgr`` bug that caused mgr becoming unresponsive on
  larger clusters `issue#43364 <https://tracker.ceph.com/issues/43364>`_ (`pr#32466 <https://github.com/ceph/ceph/pull/32466>`_, David Zafman, Neha Ojha)


v14.2.5 Nautilus
================

This is the fifth release of the Ceph Nautilus release series. Among the many
notable changes, this release fixes a critical BlueStore bug that was introduced
in 14.2.3. All Nautilus users are advised to upgrade to this release.

Notable Changes
---------------

Critical fix:

* This release fixes a `critical BlueStore bug <https://tracker.ceph.com/issues/42223>`_
  introduced in 14.2.3 (and also present in 14.2.4) that can lead to data
  corruption when a separate "WAL" device is used.

New health warnings:

* Ceph will now issue health warnings if daemons have recently crashed. Ceph
  has been collecting crash reports since the initial Nautilus release, but the
  health alerts are new. To view new crashes (or all crashes, if you've just
  upgraded)::

    ceph crash ls-new

  To acknowledge a particular crash (or all crashes) and silence the health warning::

    ceph crash archive <crash-id>
    ceph crash archive-all

* 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
  recommended value::

    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

* A health warning is now generated if the average osd heartbeat ping
  time exceeds a configurable threshold for any of the intervals
  computed. The OSD computes 1 minute, 5 minute and 15 minute
  intervals with average, minimum and maximum values.  New configuration
  option `mon_warn_on_slow_ping_ratio` specifies a percentage of
  `osd_heartbeat_grace` to determine the threshold.  A value of zero
  disables the warning. New configuration option `mon_warn_on_slow_ping_time`
  specified in milliseconds over-rides the computed value, causes a warning
  when OSD heartbeat pings take longer than the specified amount.
  A new admin command, `ceph daemon mgr.# dump_osd_network [threshold]`, will
  list all connections with a ping time longer than the specified threshold or
  value determined by the config options, for the average for any of the 3 intervals.
  Another new admin command, `ceph daemon osd.# dump_osd_network [threshold]`,
  will do the same but only including heartbeats initiated by the specified OSD.

Changes in the telemetry module:

* The telemetry module now reports more information.

  First, there is a new 'device' channel, enabled by default, that
  will report anonymized hard disk and SSD health metrics to
  telemetry.ceph.com in order to build and improve device failure
  prediction algorithms.  If you are not comfortable sharing device
  metrics, you can disable that channel first before re-opting-in::

    ceph config set mgr mgr/telemetry/channel_device false

  Second, we now report more information about CephFS file systems,
  including:

    - how many MDS daemons (in total and per file system)
    - which features are (or have been) enabled
    - how many data pools
    - approximate file system age (year + month of creation)
    - how many files, bytes, and snapshots
    - how much metadata is being cached

  We have also added:

    - which Ceph release the monitors are running
    - whether msgr v1 or v2 addresses are used for the monitors
    - whether IPv4 or IPv6 addresses are used for the monitors
    - whether RADOS cache tiering is enabled (and which mode)
    - whether pools are replicated or erasure coded, and
      which erasure code profile plugin and parameters are in use
    - how many hosts are in the cluster, and how many hosts have each type of daemon
    - whether a separate OSD cluster network is being used
    - how many RBD pools and images are in the cluster, and how many pools have RBD mirroring enabled
    - how many RGW daemons, zones, and zonegroups are present; which RGW frontends are in use
    - aggregate stats about the CRUSH map, like which algorithms are used, how
      big buckets are, how many rules are defined, and what tunables are in
      use

  If you had telemetry enabled, you will need to re-opt-in with::

    ceph telemetry on

  You can view exactly what information will be reported first with::

    ceph telemetry show        # see everything
    ceph telemetry show basic  # basic cluster info (including all of the new info)

OSD:

* A new OSD daemon command, 'dump_recovery_reservations', reveals the
  recovery locks held (in_progress) and waiting in priority queues.

* Another new OSD daemon command, 'dump_scrub_reservations', reveals the
  scrub reservations that are held for local (primary) and remote (replica) PGs.

RGW:

* RGW now supports S3 Object Lock set of APIs allowing for a WORM model for
  storing objects. 6 new APIs have been added put/get bucket object lock,
  put/get object retention, put/get object legal hold.

* RGW now supports List Objects V2

v14.2.4 Nautilus
================

This is the fourth release in the Ceph Nautilus stable release series. Its sole
purpose is to fix a regression that found its way into the previous release.

Notable Changes
---------------

* The ceph-volume in Nautilus v14.2.3 was found to contain a serious
  regression, described in ``https://tracker.ceph.com/issues/41660``, which 
  prevented deployment tools like ceph-ansible, DeepSea, Rook, etc. from 
  deploying/removing OSDs.

Changelog
---------

* ceph-volume: fix stderr failure to decode/encode when redirected (`pr#30300 <https://github.com/ceph/ceph/pull/30300>`_, Alfredo Deza)


v14.2.3 Nautilus
================

This is the third bug fix release of Ceph Nautilus release series. We recommend
all Nautilus users upgrade to this release. For upgrading from older releases of
ceph, general guidelines for upgrade to nautilus must be followed
:ref:`nautilus-old-upgrade`.

Notable Changes
---------------

* `CVE-2019-10222` - Fixed a denial of service vulnerability where an
  unauthenticated client of Ceph Object Gateway could trigger a crash from an
  uncaught exception

* Nautilus-based librbd clients can now open images on Jewel clusters.

* The RGW `num_rados_handles` has been removed. If you were using a value of
  `num_rados_handles` greater than 1, multiply your current
  `objecter_inflight_ops` and `objecter_inflight_op_bytes` parameters by the
  old `num_rados_handles` to get the same throttle behavior.

* The secure mode of Messenger v2 protocol is no longer experimental with this
  release. This mode is now the preferred mode of connection for monitors.

* "osd_deep_scrub_large_omap_object_key_threshold" has been lowered to detect an
  object with large number of omap keys more easily.

* The Ceph Dashboard now supports silencing Prometheus alert notifications.

v14.2.2 Nautilus
================

This is the second bug fix release of Ceph Nautilus release series. We recommend
all Nautilus users upgrade to this release. For upgrading from older releases of
ceph, general guidelines for upgrade to nautilus must be followed
:ref:`nautilus-old-upgrade`.

Notable Changes
---------------

* The no{up,down,in,out} related commands have been revamped.
  There are now 2 ways to set the no{up,down,in,out} flags:
  the old 'ceph osd [un]set <flag>' command, which sets cluster-wide flags;
  and the new 'ceph osd [un]set-group <flags> <who>' command,
  which sets flags in batch at the granularity of any crush node,
  or device class.

* radosgw-admin introduces two subcommands that allow the
  managing of expire-stale objects that might be left behind after a
  bucket reshard in earlier versions of RGW. One subcommand lists such
  objects and the other deletes them. Read the troubleshooting section
  of the dynamic resharding docs for details.

* Earlier Nautilus releases (14.2.1 and 14.2.0) have an issue where
  deploying a single new (Nautilus) BlueStore OSD on an upgraded
  cluster (i.e. one that was originally deployed pre-Nautilus) breaks
  the pool utilization stats reported by ``ceph df``.  Until all OSDs
  have been reprovisioned or updated (via ``ceph-bluestore-tool
  repair``), the pool stats will show values that are lower than the
  true value.  This is resolved in 14.2.2, such that the cluster only
  switches to using the more accurate per-pool stats after *all* OSDs
  are 14.2.2 (or later), are BlueStore, and (if they were created
  prior to Nautilus) have been updated via the ``repair`` function.

* The default value for `mon_crush_min_required_version` has been
  changed from `firefly` to `hammer`, which means the cluster will
  issue a health warning if your CRUSH tunables are older than hammer.
  There is generally a small (but non-zero) amount of data that will
  move around by making the switch to hammer tunables; for more information,
  see :ref:`crush-map-tunables`.

  If possible, we recommend that you set the oldest allowed client to `hammer`
  or later.  You can tell what the current oldest allowed client is with::

    ceph osd dump | grep min_compat_client

  If the current value is older than hammer, you can tell whether it
  is safe to make this change by verifying that there are no clients
  older than hammer current connected to the cluster with::

    ceph features

  The newer `straw2` CRUSH bucket type was introduced in hammer, and
  ensuring that all clients are hammer or newer allows new features
  only supported for `straw2` buckets to be used, including the
  `crush-compat` mode for the :ref:`balancer`.

v14.2.1 Nautilus
================

This is the first bug fix release of Ceph Nautilus release series. We recommend
all nautilus users upgrade to this release. For upgrading from older releases of
ceph, general guidelines for upgrade to nautilus must be followed
:ref:`nautilus-old-upgrade`.

Notable Changes
---------------

* Ceph now packages python bindings for python3.6 instead of
  python3.4, because EPEL7 recently switched from python3.4 to
  python3.6 as the native python3. see the `announcement <https://lists.fedoraproject.org/archives/list/epel-announce@lists.fedoraproject.org/message/EGUMKAIMPK2UD5VSHXM53BH2MBDGDWMO/>`_
  for more details on the background of this change.

Known Issues
------------

* Nautilus-based librbd clients cannot open images stored on pre-Luminous
  clusters

v14.2.0 Nautilus
================

This is the first stable release of Ceph Nautilus.

Major Changes from Mimic
------------------------

- *Dashboard*:

  The :ref:`mgr-dashboard` has gained a lot of new functionality:

  * Support for multiple users / roles
  * SSO (SAMLv2) for user authentication
  * Auditing support
  * New landing page, showing more metrics and health info
  * I18N support
  * REST API documentation with Swagger API

  New Ceph management features include:

  * OSD management (mark as down/out, change OSD settings, recovery profiles)
  * Cluster config settings editor
  * Ceph Pool management (create/modify/delete)
  * ECP management
  * RBD mirroring configuration
  * Embedded Grafana Dashboards (derived from Ceph Metrics)
  * CRUSH map viewer
  * NFS Ganesha management
  * iSCSI target management (via :ref:`ceph-iscsi`)
  * RBD QoS configuration
  * Ceph Manager (ceph-mgr) module management
  * Prometheus alert Management

  Also, the Ceph Dashboard is now split into its own package named
  ``ceph-mgr-dashboard``. You might want to install it separately,
  if your package management software fails to do so when it installs
  ``ceph-mgr``.

- *RADOS*:

  * The number of placement groups (PGs) per pool can now be decreased
    at any time, and the cluster can :ref:`automatically tune the PG count <pg-autoscaler>`
    based on cluster utilization or administrator hints.
  * The new :ref:`v2 wire protocol <msgr2>` brings support for encryption on the wire.
  * Physical :ref:`storage devices <devices>` consumed by OSD and Monitor daemons are
    now tracked by the cluster along with health metrics (i.e.,
    SMART), and the cluster can apply a pre-trained prediction model
    or a cloud-based prediction service to :ref:`warn about expected
    HDD or SSD failures <diskprediction>`.
  * The NUMA node for OSD daemons can easily be monitored via the
    ``ceph osd numa-status`` command, and configured via the
    ``osd_numa_node`` config option.
  * When BlueStore OSDs are used, space utilization is now broken down
    by object data, omap data, and internal metadata, by pool, and by
    pre- and post- compression sizes.
  * OSDs more effectively prioritize the most important PGs and
    objects when performing recovery and backfill.
  * Progress for long-running background processes--like recovery
    after a device failure--is now reported as part of ``ceph
    status``.
  * An experimental `Coupled-Layer "Clay" erasure code
    <https://www.usenix.org/conference/fast18/presentation/vajha>`_
    plugin has been added that reduces network bandwidth and IO needed
    for most recovery operations.

- *RGW*:

  * S3 lifecycle transition for tiering between storage classes.
  * A new web frontend (Beast) has replaced civetweb as the default,
    improving overall performance.
  * A new publish/subscribe infrastructure allows RGW to feed events
    to serverless frameworks like knative or data pipelies like Kafka.
  * A range of authentication features, including STS federation using
    OAuth2 and OpenID::connect and an OPA (Open Policy Agent)
    authentication delegation prototype.
  * The new archive zone federation feature enables full preservation
    of all objects (including history) in a separate zone.

- *CephFS*:

  * MDS stability has been greatly improved for large caches and
    long-running clients with a lot of RAM. Cache trimming and client
    capability recall is now throttled to prevent overloading the MDS.
  * CephFS may now be exported via NFS-Ganesha clusters in environments managed
    by Rook. Ceph manages the clusters and ensures high-availability and
    scalability. An `introductory demo
    <https://ceph.com/community/deploying-a-cephnfs-server-cluster-with-rook/>`_
    is available. More automation of this feature is expected to be forthcoming
    in future minor releases of Nautilus.
  * The MDS ``mds_standby_for_*``, ``mon_force_standby_active``, and
    ``mds_standby_replay`` configuration options have been obsoleted. Instead,
    the operator :ref:`may now set <mds-standby-replay>` the new
    ``allow_standby_replay`` flag on the CephFS file system. This setting
    causes standbys to become standby-replay for any available rank in the file
    system.
  * MDS now supports dropping its cache which concurrently asks clients
    to trim their caches. This is done using MDS admin socket ``cache drop``
    command.
  * It is now possible to check the progress of an on-going scrub in the MDS.
    Additionally, a scrub may be paused or aborted. See :ref:`the scrub
    documentation <mds-scrub>` for more information.
  * A new interface for creating volumes is provided via the ``ceph volume``
    command-line-interface.
  * A new cephfs-shell tool is available for manipulating a CephFS file
    system without mounting.
  * CephFS-related output from ``ceph status`` has been reformatted for brevity,
    clarity, and usefulness.
  * Lazy IO has been revamped. It can be turned on by the client using the new
    CEPH_O_LAZY flag to the ``ceph_open`` C/C++ API or via the config option
    ``client_force_lazyio``.
  * CephFS file system can now be brought down rapidly via the ``ceph fs fail``
    command. See :ref:`the administration page <cephfs-administration>` for
    more information.

- *RBD*:

  * Images can be live-migrated with minimal downtime to assist with moving
    images between pools or to new layouts.
  * New ``rbd perf image iotop`` and ``rbd perf image iostat`` commands provide
    an iotop- and iostat-like IO monitor for all RBD images.
  * The *ceph-mgr* Prometheus exporter now optionally includes an IO monitor
    for all RBD images.
  * Support for separate image namespaces within a pool for tenant isolation.

- *Misc*:

  * Ceph has a new set of :ref:`orchestrator modules
    <orchestrator-cli-module>` to directly interact with external
    orchestrators like ceph-ansible, DeepSea, Rook, or simply ssh via
    a consistent CLI (and, eventually, Dashboard) interface.

.. _nautilus-old-upgrade:

Upgrading from Mimic or Luminous
--------------------------------

Notes
~~~~~

* During the upgrade from Luminous to Nautilus, it will not be
  possible to create a new OSD using a Luminous ceph-osd daemon after
  the monitors have been upgraded to Nautilus.  We recommend you avoid adding
  or replacing any OSDs while the upgrade is in progress.

* We recommend you avoid creating any RADOS pools while the upgrade is
  in progress.

* You can monitor the progress of your upgrade at each stage with the
  ``ceph versions`` command, which will tell you what ceph version(s) are
  running for each type of daemon.

Instructions
~~~~~~~~~~~~

#. If your cluster was originally installed with a version prior to
   Luminous, ensure that it has completed at least one full scrub of
   all PGs while running Luminous.  Failure to do so will cause your
   monitor daemons to refuse to join the quorum on start, leaving them
   non-functional.

   If you are unsure whether or not your Luminous cluster has
   completed a full scrub of all PGs, you can check your cluster's
   state by running::

     # ceph osd dump | grep ^flags

   In order to be able to proceed to Nautilus, your OSD map must include
   the ``recovery_deletes`` and ``purged_snapdirs`` flags.

   If your OSD map does not contain both these flags, you can simply
   wait for approximately 24-48 hours, which in a standard cluster
   configuration should be ample time for all your placement groups to
   be scrubbed at least once, and then repeat the above process to
   recheck.

   However, if you have just completed an upgrade to Luminous and want
   to proceed to Mimic in short order, you can force a scrub on all
   placement groups with a one-line shell command, like::

     # ceph pg dump pgs_brief | cut -d " " -f 1 | xargs -n1 ceph pg scrub

   You should take into consideration that this forced scrub may
   possibly have a negative impact on your Ceph clients' performance.

#. Make sure your cluster is stable and healthy (no down or
   recovering OSDs).  (Optional, but recommended.)

#. Set the ``noout`` flag for the duration of the upgrade. (Optional,
   but recommended.)::

     # ceph osd set noout

#. Upgrade monitors by installing the new packages and restarting the
   monitor daemons.  For example, on each monitor host,::

     # systemctl restart ceph-mon.target

   Once all monitors are up, verify that the monitor upgrade is
   complete by looking for the ``nautilus`` string in the mon
   map.  The command::

     # ceph mon dump | grep min_mon_release

   should report::

     min_mon_release 14 (nautilus)

   If it doesn't, that implies that one or more monitors hasn't been
   upgraded and restarted and/or the quorum does not include all monitors.

#. Upgrade ``ceph-mgr`` daemons by installing the new packages and
   restarting all manager daemons.  For example, on each manager host,::

     # systemctl restart ceph-mgr.target

   Please note, if you are using Ceph Dashboard, you will probably need to
   install ``ceph-mgr-dashboard`` separately after upgrading ``ceph-mgr``
   package. The install script of ``ceph-mgr-dashboard`` will restart the
   manager daemons automatically for you. So in this case, you can just skip
   the step to restart the daemons.

   Verify the ``ceph-mgr`` daemons are running by checking ``ceph
   -s``::

     # ceph -s

     ...
       services:
        mon: 3 daemons, quorum foo,bar,baz
        mgr: foo(active), standbys: bar, baz
     ...
  
#. Upgrade all OSDs by installing the new packages and restarting the
   ceph-osd daemons on all OSD hosts::

     # systemctl restart ceph-osd.target

   You can monitor the progress of the OSD upgrades with the
   ``ceph versions`` or ``ceph osd versions`` commands::

     # ceph osd versions
     {
        "ceph version 13.2.5 (...) mimic (stable)": 12,
        "ceph version 14.2.0 (...) nautilus (stable)": 22,
     }

#. If there are any OSDs in the cluster deployed with ceph-disk (e.g.,
   almost any OSDs that were created before the Mimic release), you
   need to tell ceph-volume to adopt responsibility for starting the
   daemons.  On each host containing OSDs, ensure the OSDs are
   currently running, and then::

     # ceph-volume simple scan
     # ceph-volume simple activate --all

   We recommend that each OSD host be rebooted following this step to
   verify that the OSDs start up automatically.

   Note that ceph-volume doesn't have the same hot-plug capability
   that ceph-disk did, where a newly attached disk is automatically
   detected via udev events.  If the OSD isn't currently running when the
   above ``scan`` command is run, or a ceph-disk-based OSD is moved to
   a new host, or the host OSD is reinstalled, or the
   ``/etc/ceph/osd`` directory is lost, you will need to scan the main
   data partition for each ceph-disk OSD explicitly.  For example,::

     # ceph-volume simple scan /dev/sdb1

   The output will include the appropriate ``ceph-volume simple
   activate`` command to enable the OSD.

#. Upgrade all CephFS MDS daemons.  For each CephFS file system,

   #. Reduce the number of ranks to 1.  (Make note of the original
      number of MDS daemons first if you plan to restore it later.)::

	# ceph status
	# ceph fs set <fs_name> max_mds 1

   #. Wait for the cluster to deactivate any non-zero ranks by
      periodically checking the status::

	# ceph status

   #. Take all standby MDS daemons offline on the appropriate hosts with::

	# systemctl stop ceph-mds@<daemon_name>

   #. Confirm that only one MDS is online and is rank 0 for your FS::

	# ceph status

   #. Upgrade the last remaining MDS daemon by installing the new
      packages and restarting the daemon::

        # systemctl restart ceph-mds.target

   #. Restart all standby MDS daemons that were taken offline::

	# systemctl start ceph-mds.target

   #. Restore the original value of ``max_mds`` for the volume::

	# ceph fs set <fs_name> max_mds <original_max_mds>

#. Upgrade all radosgw daemons by upgrading packages and restarting
   daemons on all hosts::

     # systemctl restart ceph-radosgw.target

#. Complete the upgrade by disallowing pre-Nautilus OSDs and enabling
   all new Nautilus-only functionality::

     # ceph osd require-osd-release nautilus

   .. important:: This step is mandatory. Failure to execute this step will make it impossible for OSDs to communicate after msgrv2 is enabled.

#. If you set ``noout`` at the beginning, be sure to clear it with::

     # ceph osd unset noout

#. Verify the cluster is healthy with ``ceph health``.

   If your CRUSH tunables are older than Hammer, Ceph will now issue a
   health warning.  If you see a health alert to that effect, you can
   revert this change with::

     ceph config set mon mon_crush_min_required_version firefly

   If Ceph does not complain, however, then we recommend you also
   switch any existing CRUSH buckets to straw2, which was added back
   in the Hammer release.  If you have any 'straw' buckets, this will
   result in a modest amount of data movement, but generally nothing
   too severe.::

     ceph osd getcrushmap -o backup-crushmap
     ceph osd crush set-all-straw-buckets-to-straw2

   If there are problems, you can easily revert with::

     ceph osd setcrushmap -i backup-crushmap

   Moving to 'straw2' buckets will unlock a few recent features, like
   the `crush-compat` :ref:`balancer <balancer>` mode added back in Luminous.

#. To enable the new :ref:`v2 network protocol <msgr2>`, issue the
   following command::

     ceph mon enable-msgr2

   This will instruct all monitors that bind to the old default port
   6789 for the legacy v1 protocol to also bind to the new 3300 v2
   protocol port.  To see if all monitors have been updated,::

     ceph mon dump

   and verify that each monitor has both a ``v2:`` and ``v1:`` address
   listed.

   Running nautilus OSDs will not bind to their v2 address automatically.
   They must be restarted for that to happen.

   .. important:: 
      Before this step is run, the following command must already have been run:

      # ceph osd require-osd-release nautilus

      If this command (step 10 in this procedure) has not been run, OSDs will lose the ability to communicate.

#. For each host that has been upgraded, you should update your
   ``ceph.conf`` file so that it either specifies no monitor port (if
   you are running the monitors on the default ports) or references
   both the v2 and v1 addresses and ports explicitly.  Things will
   still work if only the v1 IP and port are listed, but each CLI
   instantiation or daemon will need to reconnect after learning the
   monitors also speak the v2 protocol, slowing things down a bit and
   preventing a full transition to the v2 protocol.

   This is also a good time to fully transition any config options in
   ``ceph.conf`` into the cluster's configuration database.  On each host,
   you can use the following command to import any options into the
   monitors with::

     ceph config assimilate-conf -i /etc/ceph/ceph.conf

   You can see the cluster's configuration database with::

     ceph config dump
     
   To create a minimal but sufficient ``ceph.conf`` for each host,::

     ceph config generate-minimal-conf > /etc/ceph/ceph.conf.new
     mv /etc/ceph/ceph.conf.new /etc/ceph/ceph.conf

   Be sure to use this new config only on hosts that have been
   upgraded to Nautilus, as it may contain a ``mon_host`` value that
   includes the new ``v2:`` and ``v1:`` prefixes for IP addresses that
   is only understood by Nautilus.

   For more information, see :ref:`msgr2_ceph_conf`.

#. Consider enabling the :ref:`telemetry module <telemetry>` to send
   anonymized usage statistics and crash information to the Ceph
   upstream developers.  To see what would be reported (without actually
   sending any information to anyone),::

     ceph mgr module enable telemetry
     ceph telemetry show

   If you are comfortable with the data that is reported, you can opt-in to
   automatically report the high-level cluster metadata with::

     ceph telemetry on

   For more information about the telemetry module, see :ref:`the
   documentation <telemetry>`.


Upgrading from pre-Luminous releases (like Jewel)
-------------------------------------------------

You *must* first upgrade to Luminous (12.2.z) before attempting an
upgrade to Nautilus.  In addition, your cluster must have completed at
least one scrub of all PGs while running Luminous, setting the
``recovery_deletes`` and ``purged_snapdirs`` flags in the OSD map.


Upgrade compatibility notes
---------------------------

These changes occurred between the Mimic and Nautilus releases.

* ``ceph pg stat`` output has been modified in json
  format to match ``ceph df`` output:

  - "raw_bytes" field renamed to "total_bytes"
  - "raw_bytes_avail" field renamed to "total_bytes_avail"
  - "raw_bytes_avail" field renamed to "total_bytes_avail"
  - "raw_bytes_used" field renamed to "total_bytes_raw_used"
  - "total_bytes_used" field added to represent the space (accumulated over
     all OSDs) allocated purely for data objects kept at block(slow) device
  
* ``ceph df [detail]`` output (GLOBAL section) has been modified in plain
  format:

  - new 'USED' column shows the space (accumulated over all OSDs) allocated
    purely for data objects kept at block(slow) device.
  - 'RAW USED' is now a sum of 'USED' space and space allocated/reserved at
     block device for Ceph purposes, e.g. BlueFS part for BlueStore.

* ``ceph df [detail]`` output (GLOBAL section) has been modified in json
  format:
  
  - 'total_used_bytes' column now shows the space (accumulated over all OSDs)
    allocated purely for data objects kept at block(slow) device
  - new 'total_used_raw_bytes' column shows a sum of 'USED' space and space
    allocated/reserved at block device for Ceph purposes, e.g. BlueFS part for
    BlueStore.

* ``ceph df [detail]`` output (POOLS section) has been modified in plain
  format:
  
  - 'BYTES USED' column renamed to 'STORED'. Represents amount of data
    stored by the user.
  - 'USED' column now represent amount of space allocated purely for data
    by all OSD nodes in KB.
  - 'QUOTA BYTES', 'QUOTA OBJECTS' aren't showed anymore in non-detailed mode.
  - new column 'USED COMPR' - amount of space allocated for compressed
    data. i.e., compressed data plus all the allocation, replication and erasure
    coding overhead.
  - new column 'UNDER COMPR' - amount of data passed through compression
    (summed over all replicas) and beneficial enough to be stored in a
    compressed form.
  - Some columns reordering

* ``ceph df [detail]`` output (POOLS section) has been modified in json
  format:
  
  - 'bytes used' column renamed to 'stored'. Represents amount of data
    stored by the user.
  - 'raw bytes used' column renamed to "stored_raw". Totals of user data
     over all OSD excluding degraded.
  - new 'bytes_used' column now represent amount of space allocated by 
    all OSD nodes.
  - 'kb_used' column - the same as 'bytes_used' but in KB.
  - new column 'compress_bytes_used' - amount of space allocated for compressed
    data. i.e., compressed data plus all the allocation, replication and erasure
    coding overhead.
  - new column 'compress_under_bytes' amount of data passed through compression
    (summed over all replicas) and beneficial enough to be stored in a
    compressed form.

* ``rados df [detail]`` output (POOLS section) has been modified in plain
  format:
  
  - 'USED' column now shows the space (accumulated over all OSDs) allocated
    purely for data objects kept at block(slow) device.
  - new column 'USED COMPR' - amount of space allocated for compressed
    data. i.e., compressed data plus all the allocation, replication and erasure
    coding overhead.
  - new column 'UNDER COMPR' - amount of data passed through compression
    (summed over all replicas) and beneficial enough to be stored in a
    compressed form.

* ``rados df [detail]`` output (POOLS section) has been modified in json
  format:
  
  - 'size_bytes' and 'size_kb' columns now show the space (accumulated
    over all OSDs) allocated purely for data objects kept at block
    device.
  - new column 'compress_bytes_used' - amount of space allocated for compressed
    data. i.e., compressed data plus all the allocation, replication and erasure
    coding overhead.
  - new column 'compress_under_bytes' amount of data passed through compression
    (summed over all replicas) and beneficial enough to be stored in a
    compressed form.

* ``ceph pg dump`` output (totals section) has been modified in json
  format:
  
  - new 'USED' column shows the space (accumulated over all OSDs) allocated
    purely for data objects kept at block(slow) device.
  - 'USED_RAW' is now a sum of 'USED' space and space allocated/reserved at
    block device for Ceph purposes, e.g. BlueFS part for BlueStore.

* The ``ceph osd rm`` command has been deprecated.  Users should use
  ``ceph osd destroy`` or ``ceph osd purge`` (but after first confirming it is
  safe to do so via the ``ceph osd safe-to-destroy`` command).

* The MDS now supports dropping its cache for the purposes of benchmarking.::

    ceph tell mds.* cache drop <timeout>

  Note that the MDS cache is cooperatively managed by the clients. It is
  necessary for clients to give up capabilities in order for the MDS to fully
  drop its cache. This is accomplished by asking all clients to trim as many
  caps as possible. The timeout argument to the ``cache drop`` command controls
  how long the MDS waits for clients to complete trimming caps. This is optional
  and is 0 by default (no timeout). Keep in mind that clients may still retain
  caps to open files which will prevent the metadata for those files from being
  dropped by both the client and the MDS. (This is an equivalent scenario to
  dropping the Linux page/buffer/inode/dentry caches with some processes pinning
  some inodes/dentries/pages in cache.)

* The ``mon_health_preluminous_compat`` and
  ``mon_health_preluminous_compat_warning`` config options are
  removed, as the related functionality is more than two versions old.
  Any legacy monitoring system expecting Jewel-style health output
  will need to be updated to work with Nautilus.

* Nautilus is not supported on any distros still running upstart so upstart
  specific files and references have been removed.

* The ``ceph pg <pgid> list_missing`` command has been renamed to
  ``ceph pg <pgid> list_unfound`` to better match its behaviour.

* The *rbd-mirror* daemon can now retrieve remote peer cluster configuration
  secrets from the monitor. To use this feature, the rbd-mirror daemon
  CephX user for the local cluster must use the ``profile rbd-mirror`` mon cap.
  The secrets can be set using the ``rbd mirror pool peer add`` and
  ``rbd mirror pool peer set`` actions.

* The 'rbd-mirror' daemon will now run in active/active mode by default, where
  mirrored images are evenly distributed between all active 'rbd-mirror'
  daemons. To revert to active/passive mode, override the
  'rbd_mirror_image_policy_type' config key to 'none'.

* The ``ceph mds deactivate`` is fully obsolete and references to it in the docs
  have been removed or clarified.

* The libcephfs bindings added the ``ceph_select_filesystem`` function
  for use with multiple filesystems.

* The cephfs python bindings now include ``mount_root`` and ``filesystem_name``
  options in the mount() function.

* erasure-code: add experimental *Coupled LAYer (CLAY)* erasure codes
  support. It features less network traffic and disk I/O when performing
  recovery.

* The ``cache drop`` OSD command has been added to drop an OSD's caches:

    - ``ceph tell osd.x cache drop``

* The ``cache status`` OSD command has been added to get the cache stats of an
  OSD:

    - ``ceph tell osd.x cache status``

* The libcephfs added several functions that allow restarted client to destroy
  or reclaim state held by a previous incarnation. These functions are for NFS
  servers.

* The ``ceph`` command line tool now accepts keyword arguments in
  the format ``--arg=value`` or ``--arg value``.

* ``librados::IoCtx::nobjects_begin()`` and
  ``librados::NObjectIterator`` now communicate errors by throwing a
  ``std::system_error`` exception instead of ``std::runtime_error``.

* The callback function passed to ``LibRGWFS.readdir()`` now accepts a ``flags``
  parameter. it will be the last parameter passed to  ``readdir()`` method.

* The ``cephfs-data-scan scan_links`` now automatically repair inotables and
  snaptable.

* Configuration values ``mon_warn_not_scrubbed`` and
  ``mon_warn_not_deep_scrubbed`` have been renamed.  They are now
  ``mon_warn_pg_not_scrubbed_ratio`` and ``mon_warn_pg_not_deep_scrubbed_ratio``
  respectively.  This is to clarify that these warnings are related to
  pg scrubbing and are a ratio of the related interval.  These options
  are now enabled by default.

* The MDS cache trimming is now throttled. Dropping the MDS cache
  via the ``ceph tell mds.<foo> cache drop`` command or large reductions in the
  cache size will no longer cause service unavailability.

* The CephFS MDS behavior with recalling caps has been significantly improved
  to not attempt recalling too many caps at once, leading to instability.
  MDS with a large cache (64GB+) should be more stable.

* MDS now provides a config option ``mds_max_caps_per_client`` (default: 1M) to
  limit the number of caps a client session may hold. Long running client
  sessions with a large number of caps have been a source of instability in the
  MDS when all of these caps need to be processed during certain session
  events. It is recommended to not unnecessarily increase this value.

* The MDS config ``mds_recall_state_timeout`` has been removed. Late
  client recall warnings are now generated based on the number of caps
  the MDS has recalled which have not been released. The new configs
  ``mds_recall_warning_threshold`` (default: 32K) and
  ``mds_recall_warning_decay_rate`` (default: 60s) sets the threshold
  for this warning.

* The Telegraf module for the Manager allows for sending statistics to
  an Telegraf Agent over TCP, UDP or a UNIX Socket. Telegraf can then
  send the statistics to databases like InfluxDB, ElasticSearch, Graphite
  and many more.

* The graylog fields naming the originator of a log event have
  changed: the string-form name is now included (e.g., ``"name":
  "mgr.foo"``), and the rank-form name is now in a nested section
  (e.g., ``"rank": {"type": "mgr", "num": 43243}``).

* If the cluster log is directed at syslog, the entries are now
  prefixed by both the string-form name and the rank-form name (e.g.,
  ``mgr.x mgr.12345 ...`` instead of just ``mgr.12345 ...``).

* The JSON output of the ``ceph osd find`` command has replaced the ``ip``
  field with an ``addrs`` section to reflect that OSDs may bind to
  multiple addresses.

* CephFS clients without the 's' flag in their authentication capability
  string will no longer be able to create/delete snapshots. To allow
  ``client.foo`` to create/delete snapshots in the ``bar`` directory of
  filesystem ``cephfs_a``, use command:

    - ``ceph auth caps client.foo mon 'allow r' osd 'allow rw tag cephfs data=cephfs_a' mds 'allow rw, allow rws path=/bar'``

* The ``osd_heartbeat_addr`` option has been removed as it served no
  (good) purpose: the OSD should always check heartbeats on both the
  public and cluster networks.

* The ``rados`` tool's ``mkpool`` and ``rmpool`` commands have been
  removed because they are redundant; please use the ``ceph osd pool
  create`` and ``ceph osd pool rm`` commands instead.

* The ``auid`` property for cephx users and RADOS pools has been
  removed.  This was an undocumented and partially implemented
  capability that allowed cephx users to map capabilities to RADOS
  pools that they "owned".  Because there are no users we have removed
  this support.  If any cephx capabilities exist in the cluster that
  restrict based on auid then they will no longer parse, and the
  cluster will report a health warning like::

    AUTH_BAD_CAPS 1 auth entities have invalid capabilities
        client.bad osd capability parse failed, stopped at 'allow rwx auid 123' of 'allow rwx auid 123'

  The capability can be adjusted with the ``ceph auth caps``
  command. For example,::

    ceph auth caps client.bad osd 'allow rwx pool foo'

* The ``ceph-kvstore-tool`` ``repair`` command has been renamed
  ``destructive-repair`` since we have discovered it can corrupt an
  otherwise healthy rocksdb database.  It should be used only as a last-ditch
  attempt to recover data from an otherwise corrupted store.


* The default memory utilization for the mons has been increased
  somewhat.  Rocksdb now uses 512 MB of RAM by default, which should
  be sufficient for small to medium-sized clusters; large clusters
  should tune this up.  Also, the ``mon_osd_cache_size`` has been
  increase from 10 OSDMaps to 500, which will translate to an
  additional 500 MB to 1 GB of RAM for large clusters, and much less
  for small clusters.

* The ``mgr/balancer/max_misplaced`` option has been replaced by a new
  global ``target_max_misplaced_ratio`` option that throttles both
  balancer activity and automated adjustments to ``pgp_num`` (normally as a
  result of ``pg_num`` changes).  If you have customized the balancer module
  option, you will need to adjust your config to set the new global option
  or revert to the default of .05 (5%).

* By default, Ceph no longer issues a health warning when there are
  misplaced objects (objects that are fully replicated but not stored
  on the intended OSDs).  You can reenable the old warning by setting
  ``mon_warn_on_misplaced`` to ``true``.

* The ``ceph-create-keys`` tool is now obsolete.  The monitors
  automatically create these keys on their own.  For now the script
  prints a warning message and exits, but it will be removed in the
  next release.  Note that ``ceph-create-keys`` would also write the
  admin and bootstrap keys to /etc/ceph and /var/lib/ceph, but this
  script no longer does that.  Any deployment tools that relied on
  this behavior should instead make use of the ``ceph auth export
  <entity-name>`` command for whichever key(s) they need.

* The ``mon_osd_pool_ec_fast_read`` option has been renamed
  ``osd_pool_default_ec_fast_read`` to be more consistent with other
  ``osd_pool_default_*`` options that affect default values for newly
  created RADOS pools.

* The ``mon addr`` configuration option is now deprecated.  It can
  still be used to specify an address for each monitor in the
  ``ceph.conf`` file, but it only affects cluster creation and
  bootstrapping, and it does not support listing multiple addresses
  (e.g., both a v2 and v1 protocol address).  We strongly recommend
  the option be removed and instead a single ``mon host`` option be
  specified in the ``[global]`` section to allow daemons and clients
  to discover the monitors.

* New command ``ceph fs fail`` has been added to quickly bring down a file
  system. This is a single command that unsets the joinable flag on the file
  system and brings down all of its ranks.

* The ``cache drop`` admin socket command has been removed. The ``ceph
  tell mds.X cache drop`` remains.
