v12.2.10 Luminous
=================

This is the tenth bug fix release of the Luminous v12.2.x long term stable
release series. The previous release, v12.2.9, introduced the PG hard-limit
patches which were found to cause an issue in certain upgrade scenarios, and
this release was expedited to revert those patches. If you already successfully
upgraded to v12.2.9, you should **not** upgrade to v12.2.10, but rather **wait**
for a release in which http://tracker.ceph.com/issues/36686 is addressed. All
other users are encouraged to upgrade to this release.

Notable Changes

v12.2.9 Luminous
================

This is the ninth bug fix release of the Luminous v12.2.x long term stable
release series. Although this release contains several bugfixes across all the
components, it also introduced the PG hard-limit patches which could cause
problems during upgrade when not all PGs were active+clean. Therefore, users
should not install this release. Instead, they should skip it and upgrade to
12.2.10 directly.

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

OSD

* 12.2.9 contains the pg hard hard limit patches (https://tracker.ceph.com/issues/23979).
  A partial upgrade during recovery/backfill, can cause the osds on the
  previous version, to fail with assert(trim_to <= info.last_complete). The
  workaround for users is to upgrade and restart all OSDs to a version with the
  pg hard limit, or only upgrade when all PGs are active+clean. This patch will
  be reverted in 12.2.10, until a clean upgrade path is added to the pg log hard
  limit patches.

  See also: http://tracker.ceph.com/issues/36686

* The bluestore_cache_* options are no longer needed. They are replaced
  by osd_memory_target, defaulting to 4GB. BlueStore will expand
  and contract its cache to attempt to stay within this
  limit. Users upgrading should note this is a higher default
  than the previous bluestore_cache_size of 1GB, so OSDs using
  BlueStore will use more memory by default.

  For more details, see `BlueStore docs <http://docs.ceph.com/docs/master/rados/configuration/bluestore-config-ref/#cache-size>_`

v12.2.8 Luminous
================

This is the eighth bug fix release of the Luminous v12.2.x long term stable
release series. This release contains several bugfixes across all the components
and we recommend all users upgrade.

Upgrade Notes from previous luminous releases
---------------------------------------------

When upgrading from v12.2.5 or v12.2.6 please note that upgrade caveats from
12.2.5 will apply to any _newer_ luminous version including 12.2.8. Please read
the notes at luminous-12-2-5-upgrades_ .

For the cluster that installed the broken 12.2.6 release, 12.2.7 fixed the
regression and introduced a workaround option `osd distrust data digest = true`,
but 12.2.7 clusters still generated health warnings like ::

  [ERR] 11.288 shard 207: soid  11:1155c332:::rbd_data.207dce238e1f29.0000000000000527:head data_digest 0xc8997a5b != data_digest 0x2ca15853


12.2.8 improves the deep scrub code to automatically repair these
inconsistencies. Once the entire cluster has been upgraded and then fully deep
scrubbed, and all such inconsistencies are resolved, it will be safe to disable
the `osd distrust data digest = true` workaround option.

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

- *OSD*

  * Scrub repair is enhanced to handle data digest mismatch info on
    replicas as long as all replicas' digests match each other.

- *RGW*

  * Options `rgw curl low speed limit` and `rgw curl low speed time`
    are added to control the lower speed limits and times below which
    the requests are considered too slow to be aborted and can help
    mitigate data sync getting blocked during network issues

  * Option `rgw s3 auth order` configurable added which takes a comma
    separated list of order to try for s3 authentication when external
    engines are involved.

v12.2.7 Luminous
================

This is the seventh bugfix release of Luminous v12.2.x long term
stable release series. This release contains several fixes for
regressions in the v12.2.6 and v12.2.5 releases.  We recommend that
all users upgrade.

:note: The v12.2.6 release has serious known regressions.  If you installed this release, please see the upgrade procedure below.

:note: The v12.2.5 release has a potential data corruption issue with erasure coded pools.  If you ran v12.2.5 with erasure coding, please see below.

.. _luminous-12-2-5-upgrades:

Upgrading from v12.2.6
----------------------

v12.2.6 included an incomplete backport of an optimization for
BlueStore OSDs that avoids maintaining both the per-object checksum
and the internal BlueStore checksum.  Due to the accidental omission
of a critical follow-on patch, v12.2.6 corrupts (fails to update) the
stored per-object checksum value for some objects.  This can result in
an EIO error when trying to read those objects.

#. If your cluster uses FileStore only, no special action is required.
   This problem only affects clusters with BlueStore.

#. If your cluster has only BlueStore OSDs (no FileStore), then you
   should enable the following OSD option::

     osd skip data digest = true

   This will avoid setting and start ignoring the full-object digests
   whenever the primary for a PG is BlueStore.

#. If you have a mix of BlueStore and FileStore OSDs, then you should
   enable the following OSD option::

     osd distrust data digest = true

   This will avoid setting and start ignoring the full-object digests
   in all cases.  This weakens the data integrity checks for
   FileStore (although those checks were always only opportunistic).

If your cluster includes BlueStore OSDs and was affected, deep scrubs
will generate errors about mismatched CRCs for affected objects.
Currently the repair operation does not know how to correct them
(since all replicas do not match the expected checksum it does not
know how to proceed).  These warnings are harmless in the sense that
IO is not affected and the replicas are all still in sync.  The number
of affected objects is likely to drop (possibly to zero) on their own
over time as those objects are modified.  We expect to include a scrub
improvement in v12.2.8 to clean up any remaining objects.

Additionally, see the notes below, which apply to both v12.2.5 and v12.2.6.

Upgrading from v12.2.5 or v12.2.6
---------------------------------

If you used v12.2.5 or v12.2.6 in combination with erasure coded
pools, there is a small risk of corruption under certain workloads.
Specifically, when:

* An erasure coded pool is in use
* The pool is busy with successful writes
* The pool is also busy with updates that result in an error result to
  the librados user.  RGW garbage collection is the most common
  example of this (it sends delete operations on objects that don't
  always exist.)
* Some OSDs are reasonably busy.  One known example of such load is
  FileStore splitting, although in principle any load on the cluster
  could also trigger the behavior.
* One or more OSDs restarts.

This combination can trigger an OSD crash and possibly leave PGs in a state
where they fail to peer.

Notably, upgrading a cluster involves OSD restarts and as such may
increase the risk of encountering this bug.  For this reason, for
clusters with erasure coded pools, we recommend the following upgrade
procedure to minimize risk:

#. Install the v12.2.7 packages.
#. Temporarily quiesce IO to cluster::

     ceph osd pause

#. Restart all OSDs and wait for all PGs to become active.
#. Resume IO::

     ceph osd unpause

This will cause an availability outage for the duration of the OSD
restarts.  If this in unacceptable, an *more risky* alternative is to
disable RGW garbage collection (the primary known cause of these rados
operations) for the duration of the upgrade::

#. Set ``rgw_enable_gc_threads = false`` in ceph.conf
#. Restart all radosgw daemons
#. Upgrade and restart all OSDs
#. Remove ``rgw_enable_gc_threads = false`` from ceph.conf
#. Restart all radosgw daemons

Upgrading from other versions
-----------------------------

If your cluster did not run v12.2.5 or v12.2.6 then none of the above
issues apply to you and you should upgrade normally.

v12.2.6 Luminous
================

:note: This is a broken release with serious known regressions.  Do not install it.

This is the sixth bugfix release of Luminous v12.2.x long term stable release
series. This release contains a range of bug fixes across all components of
Ceph and a few security fixes.

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

- *Auth*:

  * In 12.2.4 and earlier releases, keyring caps were not checked for validity,
    so the caps string could be anything. As of 12.2.6, caps strings are
    validated and providing a keyring with an invalid caps string to, e.g.,
    "ceph auth add" will result in an error.
  * CVE 2018-1128: auth: cephx authorizer subject to replay attack (`issue#24836 <http://tracker.ceph.com/issues/24836>`_, Sage Weil)
  * CVE 2018-1129: auth: cephx signature check is weak (`issue#24837 <http://tracker.ceph.com/issues/24837>`_, Sage Weil)
  * CVE 2018-10861: mon: auth checks not correct for pool ops (`issue#24838 <http://tracker.ceph.com/issues/24838>`_, Jason Dillaman)


* The config-key interface can store arbitrary binary blobs but JSON
  can only express printable strings.  If binary blobs are present,
  the 'ceph config-key dump' command will show them as something like
  ``<<< binary blob of length N >>>``.

v12.2.5 Luminous
================

This is the fifth bugfix release of Luminous v12.2.x long term stable
release series. This release contains a range of bug fixes across all
components of Ceph. We recommend all the users of 12.2.x series to
update.

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

* MGR

  The ceph-rest-api command-line tool included in the ceph-mon
  package has been obsoleted by the MGR "restful" module. The
  ceph-rest-api tool is hereby declared deprecated and will be dropped
  in Mimic.

  The MGR "restful" module provides similar functionality via a "pass through"
  method. See http://docs.ceph.com/docs/luminous/mgr/restful for details.

* CephFS

  Upgrading an MDS cluster to 12.2.3+ will result in all active MDS
  exiting due to feature incompatibilities once an upgraded MDS comes
  online (even as standby). Operators may ignore the error messages
  and continue upgrading/restarting or follow this upgrade sequence:

  Reduce the number of ranks to 1 (`ceph fs set <fs_name> max_mds 1`),
  wait for all other MDS to deactivate, leaving the one active MDS,
  upgrade the single active MDS, then upgrade/start standbys. Finally,
  restore the previous max_mds.

v12.2.3 Luminous
================

This is the third bugfix release of Luminous v12.2.x long term stable release
series. It contains a range of bug fixes and a few features across Bluestore,
CephFS, RBD & RGW. We recommend all the users of 12.2.x series update.

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

- *CephFS*:

  * The CephFS client now checks for older kernels' inability to reliably clear
    dentries from the kernel dentry cache. The new option
    client_die_on_failed_dentry_invalidate (default: true) may be turned off to
    allow the client to proceed (dangerous!).

v12.2.2 Luminous
================

This is the second bugfix release of Luminous v12.2.x long term stable release
series. It contains a range of bug fixes and a few features across Bluestore,
CephFS, RBD & RGW. We recommend all the users of 12.2.x series update.

For more detailed information, see :download:`the complete changelog <../changelog/v12.2.2.txt>`.


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

* Standby ceph-mgr daemons now redirect requests to the active messenger, easing
  configuration for tools & users accessing the web dashboard, restful API, or
  other ceph-mgr module services.
* The prometheus module has several significant updates and improvements.
* The new balancer module enables automatic optimization of CRUSH weights to
  balance data across the cluster.
* The ceph-volume tool has been updated to include support for BlueStore as well
  as FileStore. The only major missing ceph-volume feature is dm-crypt support.
* RGW's dynamic bucket index resharding is disabled in multisite environments,
  as it can cause inconsistencies in replication of bucket indexes to remote
  sites.

v12.2.1 Luminous
================

This is the first bugfix release of Luminous v12.2.x long term stable
release series. It contains a range of bug fixes and a few features
across CephFS, RBD & RGW. We recommend all the users of 12.2.x series
update.

For more detailed information, see :download:`the complete changelog <../changelog/v12.2.1.txt>`.


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

* Dynamic resharding is now enabled by default for RGW, RGW will now
  automatically reshard there bucket index once the index grows beyond
  `rgw_max_objs_per_shard`

* Limiting MDS cache via a memory limit is now supported using the new
  mds_cache_memory_limit config option (1GB by default).  A cache reservation
  can also be specified using mds_cache_reservation as a percentage of the
  limit (5% by default). Limits by inode count are still supported using
  mds_cache_size. Setting mds_cache_size to 0 (the default) disables the
  inode limit.

* The maximum number of PGs per OSD before the monitor issues a
  warning has been reduced from 300 to 200 PGs.  200 is still twice
  the generally recommended target of 100 PGs per OSD.  This limit can
  be adjusted via the ``mon_max_pg_per_osd`` option on the
  monitors.  The older ``mon_pg_warn_max_per_osd`` option has been removed.

* Creating pools or adjusting pg_num will now fail if the change would
  make the number of PGs per OSD exceed the configured
  ``mon_max_pg_per_osd`` limit.  The option can be adjusted if it
  is really necessary to create a pool with more PGs.

* There was a bug in the PG mapping behavior of the new *upmap*
  feature. If you made use of this feature (e.g., via the `ceph osd
  pg-upmap-items` command), we recommend that all mappings be removed (via
  the `ceph osd rm-pg-upmap-items` command) before upgrading to this
  point release.

* A stall in BlueStore IO submission that was affecting many users has
  been resolved.

v12.2.0 Luminous
================

This is the first release of Luminous v12.2.x long term stable release
series.  There have been major changes since Kraken (v11.2.z) and
Jewel (v10.2.z), and the upgrade process is non-trivial. Please read
these release notes carefully.

Major Changes from Kraken
-------------------------

- *General*:

  * Ceph now has a simple, `built-in web-based dashboard
    <../mgr/dashboard>`_ for monitoring cluster status.

- *RADOS*:

  * *BlueStore*:

    - The new *BlueStore* backend for *ceph-osd* is now stable and the
      new default for newly created OSDs.  BlueStore manages data
      stored by each OSD by directly managing the physical HDDs or
      SSDs without the use of an intervening file system like XFS.
      This provides greater performance and features. See
      :doc:`/rados/configuration/storage-devices` and
      :doc:`/rados/configuration/bluestore-config-ref`.
    - BlueStore supports `full data and metadata checksums
      <../rados/configuration/bluestore-config-ref/#checksums>`_ of all
      data stored by Ceph.
    - BlueStore supports `inline compression
      <../rados/configuration/bluestore-config-ref/#inline-compression>`_ using
      zlib, snappy, or LZ4. (Ceph also supports zstd for `RGW compression
      <../man/8/radosgw-admin/#options>`_ but zstd is not recommended for
      BlueStore for performance reasons.)

  * *Erasure coded* pools now have `full support for overwrites
    <../rados/operations/erasure-code/#erasure-coding-with-overwrites>`_,
    allowing them to be used with RBD and CephFS.

  * *ceph-mgr*:

    - There is a new daemon, *ceph-mgr*, which is a required part of
      any Ceph deployment.  Although IO can continue when *ceph-mgr*
      is down, metrics will not refresh and some metrics-related calls
      (e.g., ``ceph df``) may block.  We recommend deploying several
      instances of *ceph-mgr* for reliability.  See the notes on
      `Upgrading`_ below.
    - The *ceph-mgr* daemon includes a `REST-based management API
      <../mgr/restful>`_. The API is still experimental and somewhat
      limited but will form the basis for API-based management of Ceph
      going forward.
    - *ceph-mgr* also includes a `Prometheus exporter
      <../mgr/prometheus>`_ plugin, which can provide Ceph
      perfcounters to Prometheus.
    - ceph-mgr now has a `Zabbix <../mgr/zabbix>`_ plugin. Using
      zabbix_sender it sends trapper events to a Zabbix server
      containing high-level information of the Ceph cluster. This
      makes it easy to monitor a Ceph cluster's status and send out
      notifications in case of a malfunction.

  * The overall *scalability* of the cluster has improved. We have
    successfully tested clusters with up to 10,000 OSDs.
  * Each OSD can now have a `device class
    <../rados/operations/crush-map/#device-classes>`_ associated with
    it (e.g., `hdd` or `ssd`), allowing CRUSH rules to trivially map
    data to a subset of devices in the system.  Manually writing CRUSH
    rules or manual editing of the CRUSH is normally not required.
  * There is a new `upmap <../rados/operations/upmap>`_ exception
    mechanism that allows individual PGs to be moved around to achieve
    a *perfect distribution* (this requires luminous clients).
  * Each OSD now adjusts its default configuration based on whether the
    backing device is an HDD or SSD.  Manual tuning generally not required.
  * The prototype `mClock QoS queueing algorithm
    <../rados/configuration/osd-config-ref/#qos-based-on-mclock>`_ is now
    available.
  * There is now a *backoff* mechanism that prevents OSDs from being
    overloaded by requests to objects or PGs that are not currently able to
    process IO.
  * There is a simplified `OSD replacement process
    <../rados/operations/add-or-rm-osds/#replacing-an-osd>`_ that is more
    robust.
  * You can query the supported features and (apparent) releases of
    all connected daemons and clients with `ceph features
    <../man/8/ceph#features>`_.
  * You can configure the oldest Ceph client version you wish to allow to
    connect to the cluster via ``ceph osd set-require-min-compat-client`` and
    Ceph will prevent you from enabling features that will break compatibility
    with those clients.
  * Several `sleep` settings, include ``osd_recovery_sleep``,
    ``osd_snap_trim_sleep``, and ``osd_scrub_sleep`` have been
    reimplemented to work efficiently.  (These are used in some cases
    to work around issues throttling background work.)
  * Pools are now expected to be associated with the application using them.
    Upon completing the upgrade to Luminous, the cluster will attempt to associate
    existing pools to known applications (i.e. CephFS, RBD, and RGW). In-use pools
    that are not associated to an application will generate a health warning. Any
    unassociated pools can be manually associated using the new
    ``ceph osd pool application enable`` command. For more details see
    `associate pool to application <../rados/operations/pools/#associate-pool-to-application>`_
    in the documentation.

- *RGW*:

  * RGW *metadata search* backed by ElasticSearch now supports end
    user requests service via RGW itself, and also supports custom
    metadata fields. A query language a set of RESTful APIs were
    created for users to be able to search objects by their
    metadata. New APIs that allow control of custom metadata fields
    were also added.
  * RGW now supports *dynamic bucket index sharding*. This has to be enabled via
    the `rgw dyamic resharding` configurable. As the number of objects in a
    bucket grows, RGW will automatically reshard the bucket index in response.
    No user intervention or bucket size capacity planning is required.
  * RGW introduces *server side encryption* of uploaded objects with
    three options for the management of encryption keys: automatic
    encryption (only recommended for test setups), customer provided
    keys similar to Amazon SSE-C specification, and through the use of
    an external key management service (Openstack Barbican) similar
    to Amazon SSE-KMS specification. :doc:`/radosgw/encryption`
  * RGW now has preliminary AWS-like bucket policy API support.  For
    now, policy is a means to express a range of new authorization
    concepts.  In the future it will be the foundation for additional
    auth capabilities such as STS and group policy. :doc:`/radosgw/bucketpolicy`
  * RGW has consolidated the several metadata index pools via the use of rados
    namespaces. :doc:`/radosgw/pools`
  * S3 Object Tagging API has been added; while APIs are
    supported for GET/PUT/DELETE object tags and in PUT object
    API, there is no support for tags on Policies & Lifecycle yet
  * RGW multisite now supports for enabling or disabling sync at a
    bucket level.

- *RBD*:

  * RBD now has full, stable support for *erasure coded pools* via the new
    ``--data-pool`` option to ``rbd create``.
  * RBD mirroring's rbd-mirror daemon is now highly available. We
    recommend deploying several instances of rbd-mirror for
    reliability.
  * RBD mirroring's rbd-mirror daemon should utilize unique Ceph user
    IDs per instance to support the new mirroring dashboard.
  * The default 'rbd' pool is no longer created automatically during
    cluster creation. Additionally, the name of the default pool used
    by the rbd CLI when no pool is specified can be overridden via a
    new ``rbd default pool = <pool name>`` configuration option.
  * Initial support for deferred image deletion via new ``rbd
    trash`` CLI commands. Images, even ones actively in-use by
    clones, can be moved to the trash and deleted at a later time.
  * New pool-level ``rbd mirror pool promote`` and ``rbd mirror pool
    demote`` commands to batch promote/demote all mirrored images
    within a pool.
  * Mirroring now optionally supports a configurable replication delay
    via the ``rbd mirroring replay delay = <seconds>`` configuration
    option.
  * Improved discard handling when the object map feature is enabled.
  * rbd CLI ``import`` and ``copy`` commands now detect sparse and
    preserve sparse regions.
  * Images and Snapshots will now include a creation timestamp.
  * Specifying user authorization capabilities for RBD clients has been
    simplified. The general syntax for using RBD capability profiles is
    "mon 'profile rbd' osd 'profile rbd[-read-only][ pool={pool-name}[, ...]]'".
    For more details see :doc:`/rados/operations/user-management`
    in the documentation.

- *CephFS*:

  * *Multiple active MDS daemons* is now considered stable.  The number
    of active MDS servers may be adjusted up or down on an active CephFS file
    system.
  * CephFS *directory fragmentation* is now stable and enabled by
    default on new filesystems.  To enable it on existing filesystems
    use "ceph fs set <fs_name> allow_dirfrags".  Large or very busy
    directories are sharded and (potentially) distributed across
    multiple MDS daemons automatically.
  * Directory subtrees can be explicitly pinned to specific MDS daemons in
    cases where the automatic load balancing is not desired or effective.
  * Client keys can now be created using the new ``ceph fs authorize`` command
    to create keys with access to the given CephFS file system and all of its
    data pools.
  * When running 'df' on a CephFS filesystem comprising exactly one data pool,
    the result now reflects the file storage space used and available in that
    data pool (fuse client only).

- *Miscellaneous*:

  * Release packages are now being built for *Debian Stretch*.  Note
    that QA is limited to CentOS and Ubuntu (xenial and trusty).  The
    distributions we build for now include:

    - CentOS 7 (x86_64 and aarch64)
    - Debian 8 Jessie (x86_64)
    - Debian 9 Stretch (x86_64)
    - Ubuntu 16.04 Xenial (x86_64 and aarch64)
    - Ubuntu 14.04 Trusty (x86_64)

  * A first release of Ceph for FreeBSD is available which contains a full set
    of features, other than Bluestore. It will run everything needed to build a
    storage cluster. For clients, all access methods are available, albeit
    CephFS is only accessible through a Fuse implementation. RBD images can be
    mounted on FreeBSD systems through rbd-ggate
    Ceph versions are released through the regular FreeBSD ports and packages
    system. The most current version is available as: net/ceph-devel. Once
    Luminous goes into official release, this version will be available as
    net/ceph. Future development releases will be available via net/ceph-devel
    More details about this port are in: `README.FreeBSD <https://github.com/ceph/ceph/blob/master/README.FreeBSD>`_

  * *CLI changes*:

    - The ``ceph -s`` or ``ceph status`` command has a fresh look.
    - ``ceph mgr metadata`` will dump metadata associated with each mgr
      daemon.
    - ``ceph versions`` or ``ceph {osd,mds,mon,mgr} versions``
      summarize versions of running daemons.
    - ``ceph {osd,mds,mon,mgr} count-metadata <property>`` similarly
      tabulates any other daemon metadata visible via the ``ceph
      {osd,mds,mon,mgr} metadata`` commands.
    - ``ceph features`` summarizes features and releases of connected
      clients and daemons.
    - ``ceph osd require-osd-release <release>`` replaces the old
      ``require_RELEASE_osds`` flags.
    - ``ceph osd pg-upmap``, ``ceph osd rm-pg-upmap``, ``ceph osd
      pg-upmap-items``, ``ceph osd rm-pg-upmap-items`` can explicitly
      manage `upmap` items (see :doc:`/rados/operations/upmap`).
    - ``ceph osd getcrushmap`` returns a crush map version number on
      stderr, and ``ceph osd setcrushmap [version]`` will only inject
      an updated crush map if the version matches.  This allows crush
      maps to be updated offline and then reinjected into the cluster
      without fear of clobbering racing changes (e.g., by newly added
      osds or changes by other administrators).
    - ``ceph osd create`` has been replaced by ``ceph osd new``.  This
      should be hidden from most users by user-facing tools like
      `ceph-disk`.
    - ``ceph osd destroy`` will mark an OSD destroyed and remove its
      cephx and lockbox keys.  However, the OSD id and CRUSH map entry
      will remain in place, allowing the id to be reused by a
      replacement device with minimal data rebalancing.
    - ``ceph osd purge`` will remove all traces of an OSD from the
      cluster, including its cephx encryption keys, dm-crypt lockbox
      keys, OSD id, and crush map entry.
    - ``ceph osd ls-tree <name>`` will output a list of OSD ids under
      the given CRUSH name (like a host or rack name).  This is useful
      for applying changes to entire subtrees.  For example, ``ceph
      osd down `ceph osd ls-tree rack1```.
    - ``ceph osd {add,rm}-{noout,noin,nodown,noup}`` allow the
      `noout`, `noin`, `nodown`, and `noup` flags to be applied to
      specific OSDs.
    - ``ceph osd safe-to-destroy <osd(s)>`` will report whether it is safe to
      remove or destroy OSD(s) without reducing data durability or redundancy.
    - ``ceph osd ok-to-stop <osd(s)>`` will report whether it is okay to stop
      OSD(s) without immediately compromising availability (i.e., all PGs
      should remain active but may be degraded).
    - ``ceph log last [n]`` will output the last *n* lines of the cluster
      log.
    - ``ceph mgr dump`` will dump the MgrMap, including the currently active
      ceph-mgr daemon and any standbys.
    - ``ceph mgr module ls`` will list active ceph-mgr modules.
    - ``ceph mgr module {enable,disable} <name>`` will enable or
      disable the named mgr module.  The module must be present in the
      configured `mgr_module_path` on the host(s) where `ceph-mgr` is
      running.
    - ``ceph osd crush ls <node>`` will list items (OSDs or other CRUSH nodes)
      directly beneath a given CRUSH node.
    - ``ceph osd crush swap-bucket <src> <dest>`` will swap the
      contents of two CRUSH buckets in the hierarchy while preserving
      the buckets' ids.  This allows an entire subtree of devices to
      be replaced (e.g., to replace an entire host of FileStore OSDs
      with newly-imaged BlueStore OSDs) without disrupting the
      distribution of data across neighboring devices.
    - ``ceph osd set-require-min-compat-client <release>`` configures
      the oldest client release the cluster is required to support.
      Other changes, like CRUSH tunables, will fail with an error if
      they would violate this setting.  Changing this setting also
      fails if clients older than the specified release are currently
      connected to the cluster.
    - ``ceph config-key dump`` dumps config-key entries and their
      contents.  (The existing ``ceph config-key list`` only dumps the key
      names, not the values.)
    - ``ceph config-key list`` is deprecated in favor of ``ceph config-key ls``.
    - ``ceph config-key put`` is deprecated in favor of ``ceph config-key set``.
    - ``ceph auth list`` is deprecated in favor of ``ceph auth ls``.
    - ``ceph osd crush rule list`` is deprecated in favor of ``ceph osd crush rule ls``.
    - ``ceph osd set-{full,nearfull,backfillfull}-ratio`` sets the
      cluster-wide ratio for various full thresholds (when the cluster
      refuses IO, when the cluster warns about being close to full,
      when an OSD will defer rebalancing a PG to itself,
      respectively).
    - ``ceph osd reweightn`` will specify the `reweight` values for
      multiple OSDs in a single command.  This is equivalent to a series of
      ``ceph osd reweight`` commands.
    - ``ceph osd crush {set,rm}-device-class`` manage the new
      CRUSH *device class* feature. Note that manually creating or deleting
      a device class name is generally not necessary as it will be smart
      enough to be self-managed. ``ceph osd crush class ls`` and
      ``ceph osd crush class ls-osd`` will output all existing device classes
      and a list of OSD ids under the given device class respectively.
    - ``ceph osd crush rule create-replicated`` replaces the old
      ``ceph osd crush rule create-simple`` command to create a CRUSH
      rule for a replicated pool.  Notably it takes a `class` argument
      for the *device class* the rule should target (e.g., `ssd` or
      `hdd`).
    - ``ceph mon feature ls`` will list monitor features recorded in the
      MonMap.  ``ceph mon feature set`` will set an optional feature (none of
      these exist yet).
    - ``ceph tell <daemon> help`` will now return a usage summary.
    - ``ceph fs authorize`` creates a new client key with caps automatically
      set to access the given CephFS file system.
    - The ``ceph health`` structured output (JSON or XML) no longer contains
      'timechecks' section describing the time sync status.  This
      information is now available via the 'ceph time-sync-status'
      command.
    - Certain extra fields in the ``ceph health`` structured output that
      used to appear if the mons were low on disk space (which duplicated
      the information in the normal health warning messages) are now gone.
    - The ``ceph -w`` output no longer contains audit log entries by default.
      Add a ``--watch-channel=audit`` or ``--watch-channel=*`` to see them.
    - New "ceph -w" behavior - the "ceph -w" output no longer contains
      I/O rates, available space, pg info, etc. because these are no
      longer logged to the central log (which is what ``ceph -w``
      shows). The same information can be obtained by running ``ceph pg
      stat``; alternatively, I/O rates per pool can be determined using
      ``ceph osd pool stats``. Although these commands do not
      self-update like ``ceph -w`` did, they do have the ability to
      return formatted output by providing a ``--format=<format>``
      option.
    - Added new commands ``pg force-recovery`` and
      ``pg-force-backfill``. Use them to boost recovery or backfill
      priority of specified pgs, so they're recovered/backfilled
      before any other. Note that these commands don't interrupt
      ongoing recovery/backfill, but merely queue specified pgs before
      others so they're recovered/backfilled as soon as possible. New
      commands ``pg cancel-force-recovery`` and ``pg
      cancel-force-backfill`` restore default recovery/backfill
      priority of previously forced pgs.


Major Changes from Jewel
------------------------

- *RADOS*:

  * We now default to the AsyncMessenger (``ms type = async``) instead
    of the legacy SimpleMessenger.  The most noticeable difference is
    that we now use a fixed sized thread pool for network connections
    (instead of two threads per socket with SimpleMessenger).
  * Some OSD failures are now detected almost immediately, whereas
    previously the heartbeat timeout (which defaults to 20 seconds)
    had to expire.  This prevents IO from blocking for an extended
    period for failures where the host remains up but the ceph-osd
    process is no longer running.
  * The size of encoded OSDMaps has been reduced.
  * The OSDs now quiesce scrubbing when recovery or rebalancing is in progress.

- *RGW*:

  * RGW now supports the S3 multipart object copy-part API.
  * It is possible now to reshard an existing bucket offline. Offline
    bucket resharding currently requires that all IO (especially
    writes) to the specific bucket is quiesced.  (For automatic online
    resharding, see the new feature in Luminous above.)
  * RGW now supports data compression for objects.
  * Civetweb version has been upgraded to 1.8
  * The Swift static website API is now supported (S3 support has been added
    previously).
  * S3 bucket lifecycle API has been added. Note that currently it only supports
    object expiration.
  * Support for custom search filters has been added to the LDAP auth
    implementation.
  * Support for NFS version 3 has been added to the RGW NFS gateway.
  * A Python binding has been created for librgw.

- *RBD*:

  * The rbd-mirror daemon now supports replicating dynamic image
    feature updates and image metadata key/value pairs from the
    primary image to the non-primary image.
  * The number of image snapshots can be optionally restricted to a
    configurable maximum.
  * The rbd Python API now supports asynchronous IO operations.

- *CephFS*:

  * libcephfs function definitions have been changed to enable proper
    uid/gid control.  The library version has been increased to reflect the
    interface change.
  * Standby replay MDS daemons now consume less memory on workloads
    doing deletions.
  * Scrub now repairs backtrace, and populates `damage ls` with
    discovered errors.
  * A new `pg_files` subcommand to `cephfs-data-scan` can identify
    files affected by a damaged or lost RADOS PG.
  * The false-positive "failing to respond to cache pressure" warnings have
    been fixed.


Upgrade from Jewel or Kraken
----------------------------
.. _Upgrading:

#. Ensure that the ``sortbitwise`` flag is enabled::

     # ceph osd set sortbitwise

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

#. Do not create any new erasure-code pools while upgrading the monitors.

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

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

     # ceph osd set noout

#. Verify that all RBD client users have sufficient caps to blacklist
   other client users. RBD client users with only ``"allow r"``
   monitor caps should be updated as follows::

     # ceph auth caps client.<ID> mon 'allow r, allow command "osd blacklist"' osd '<existing OSD caps for user>'

#. Upgrade monitors by installing the new packages and restarting the
   monitor daemons.  Note that, unlike prior releases, the ceph-mon
   daemons *must* be upgraded first::

     # systemctl restart ceph-mon.target

   Verify the monitor upgrade is complete once all monitors are up by
   looking for the ``luminous`` feature string in the mon map.  For
   example::

     # ceph mon feature ls

   should include `luminous` under persistent features::

     on current monmap (epoch NNN)
        persistent: [kraken,luminous]
        required: [kraken,luminous]

#. Add or restart ``ceph-mgr`` daemons.  If you are upgrading from
   kraken, upgrade packages and restart ceph-mgr daemons with::

     # systemctl restart ceph-mgr.target

   If you are upgrading from kraken, you may already have ceph-mgr
   daemons deployed.  If not, or if you are upgrading from jewel, you
   can deploy new daemons with tools like ceph-deploy or ceph-ansible.
   For example::

     # ceph-deploy mgr create HOST

   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 hosts::

     # systemctl restart ceph-osd.target

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

     # ceph osd versions
     {
        "ceph version 12.2.0 (...) luminous (stable)": 12,
        "ceph version 10.2.6 (...)": 3,
     }

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

     # systemctl restart ceph-mds.target

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

     # systemctl restart radosgw.target

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

     # ceph osd require-osd-release luminous

   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``.


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

You *must* first upgrade to Jewel (10.2.z) before attempting an
upgrade to Luminous.

Upgrade compatibility notes, Jewel to Kraken
--------------------------------------------

These changes occurred between the Jewel and Kraken releases and will affect
upgrades from Jewel to Luminous.

* The ``osd crush location`` config option is no longer supported.  Please
  update your ceph.conf to use the ``crush location`` option instead.  Be sure
  to update your config file to avoid any movement of OSDs from your customized
  location back to the default one.

* The OSDs now avoid starting new scrubs while recovery is in progress.  To
  revert to the old behavior (and do not let recovery activity affect the
  scrub scheduling) you can set the following option::

    osd scrub during recovery = true

* The list of monitor hosts/addresses for building the monmap can now be
  obtained from DNS SRV records. The service name used in when querying the DNS
  is defined in the "mon_dns_srv_name" config option, which defaults to
  "ceph-mon".

* The 'osd class load list' config option is a list of object class names that
  the OSD is permitted to load (or '*' for all classes). By default it
  contains all existing in-tree classes for backwards compatibility.

* The 'osd class default list' config option is a list of object class
  names (or '*' for all classes) that clients may invoke having only
  the '*', 'x', 'class-read', or 'class-write' capabilities. By
  default it contains all existing in-tree classes for backwards
  compatibility. Invoking classes not listed in 'osd class default
  list' requires a capability naming the class (e.g. 'allow class
  foo').

* The 'rgw rest getusage op compat' config option allows you to dump
  (or not dump) the description of user stats in the S3 GetUsage
  API. This option defaults to false.  If the value is true, the
  response data for GetUsage looks like::

    "stats": {
                "TotalBytes": 516,
                "TotalBytesRounded": 1024,
                "TotalEntries": 1
             }

  If the value is false, the response for GetUsage looks as it did before::

    {
         516,
         1024,
         1
    }

* The 'osd out ...' and 'osd in ...' commands now preserve the OSD
  weight.  That is, after marking an OSD out and then in, the weight
  will be the same as before (instead of being reset to 1.0).
  Previously the mons would only preserve the weight if the mon
  automatically marked an OSD out and then in, but not when an admin
  did so explicitly.

* The 'ceph osd perf' command will display 'commit_latency(ms)' and
  'apply_latency(ms)'. Previously, the names of these two columns were
  'fs_commit_latency(ms)' and 'fs_apply_latency(ms)'. We removed the
  prefix 'fs\_' because the values are not filestore-specific.

* Monitors will no longer allow pools to be removed by default.  The
  setting mon_allow_pool_delete has to be set to true (defaults to
  false) before they allow pools to be removed.  This is a additional
  safeguard against pools being removed by accident.

* If you have manually specified the monitor user rocksdb via the
  ``mon keyvaluedb = rocksdb`` option, you will need to manually add a
  file to the mon data directory to preserve this option::

     echo rocksdb > /var/lib/ceph/mon/ceph-`hostname`/kv_backend

  New monitors will now use rocksdb by default, but if that file is
  not present, existing monitors will use leveldb.  The ``mon
  keyvaluedb`` option now only affects the backend chosen when a
  monitor is created.

* The 'osd crush initial weight' option allows you to specify a CRUSH
  weight for a newly added OSD.  Previously a value of 0 (the default)
  meant that we should use the size of the OSD's store to weight the
  new OSD.  Now, a value of 0 means it should have a weight of 0, and
  a negative value (the new default) means we should automatically
  weight the OSD based on its size.  If your configuration file
  explicitly specifies a value of 0 for this option you will need to
  change it to a negative value (e.g., -1) to preserve the current
  behavior.

* The static libraries are no longer included by the debian
  development packages (lib*-dev) as it is not required per debian
  packaging policy.  The shared (.so) versions are packaged as before.

* The libtool pseudo-libraries (.la files) are no longer included by
  the debian development packages (lib*-dev) as they are not required
  per https://wiki.debian.org/ReleaseGoals/LAFileRemoval and
  https://www.debian.org/doc/manuals/maint-guide/advanced.en.html.

* The jerasure and shec plugins can now detect SIMD instruction at
  runtime and no longer need to be explicitly configured for different
  processors.  The following plugins are now deprecated:
  jerasure_generic, jerasure_sse3, jerasure_sse4, jerasure_neon,
  shec_generic, shec_sse3, shec_sse4, and shec_neon. If you use any of
  these plugins directly you will see a warning in the mon log file.
  Please switch to using just 'jerasure' or 'shec'.

* The librados omap get_keys and get_vals operations include a start key and a
  limit on the number of keys to return.  The OSD now imposes a configurable
  limit on the number of keys and number of total bytes it will respond with,
  which means that a librados user might get fewer keys than they asked for.
  This is necessary to prevent careless users from requesting an unreasonable
  amount of data from the cluster in a single operation.  The new limits are
  configured with ``osd_max_omap_entries_per_request``, defaulting to 131,072, and
  ``osd_max_omap_bytes_per_request``, defaulting to 4MB.

* Calculation of recovery priorities has been updated.
  This could lead to unintuitive recovery prioritization
  during cluster upgrade. In case of such recovery, OSDs
  in old version would operate on different priority ranges
  than new ones. Once upgraded, cluster will operate on
  consistent values.


Upgrade compatibility notes, Kraken to Luminous
-----------------------------------------------

* The configuration option ``osd pool erasure code stripe width`` has
  been replaced by ``osd pool erasure code stripe unit``, and given
  the ability to be overridden by the erasure code profile setting
  ``stripe_unit``. For more details see
  :ref:`erasure-code-profiles`.

* rbd and cephfs can use erasure coding with bluestore. This may be
  enabled by setting ``allow_ec_overwrites`` to ``true`` for a pool. Since
  this relies on bluestore's checksumming to do deep scrubbing,
  enabling this on a pool stored on filestore is not allowed.

* The ``rados df`` JSON output now prints numeric values as numbers instead of
  strings.

* The ``mon_osd_max_op_age`` option has been renamed to
  ``mon_osd_warn_op_age`` (default: 32 seconds), to indicate we
  generate a warning at this age.  There is also a new
  ``mon_osd_err_op_age_ratio`` that is a expressed as a multiple of
  ``mon_osd_warn_op_age`` (default: 128, for roughly 60 minutes) to
  control when an error is generated.

* The default maximum size for a single RADOS object has been reduced from
  100GB to 128MB.  The 100GB limit was completely impractical in practice
  while the 128MB limit is a bit high but not unreasonable.  If you have an
  application written directly to librados that is using objects larger than
  128MB you may need to adjust ``osd_max_object_size``.

* The semantics of the ``rados ls`` and librados object listing
  operations have always been a bit confusing in that "whiteout"
  objects (which logically don't exist and will return ENOENT if you
  try to access them) are included in the results.  Previously
  whiteouts only occurred in cache tier pools.  In luminous, logically
  deleted but snapshotted objects now result in a whiteout object, and
  as a result they will appear in ``rados ls`` results, even though
  trying to read such an object will result in ENOENT.  The ``rados
  listsnaps`` operation can be used in such a case to enumerate which
  snapshots are present.
  This may seem a bit strange, but is less strange than having a
  deleted-but-snapshotted object not appear at all and be completely
  hidden from librados's ability to enumerate objects.  Future
  versions of Ceph will likely include an alternative object
  enumeration interface that makes it more natural and efficient to
  enumerate all objects along with their snapshot and clone metadata.

* The deprecated ``crush_ruleset`` property has finally been removed;
  please use  ``crush_rule`` instead for the ``osd pool get ...`` and ``osd
  pool set ...`` commands.

* The ``osd pool default crush replicated ruleset`` option has been
  removed and replaced by the ``osd pool default crush rule`` option.
  By default it is -1, which means the mon will pick the first type
  replicated rule in the CRUSH map for replicated pools.  Erasure
  coded pools have rules that are automatically created for them if
  they are not specified at pool creation time.

* We no longer test the FileStore ceph-osd backend in combination with
  btrfs.  We recommend against using btrfs.  If you are using
  btrfs-based OSDs and want to upgrade to luminous you will need to
  add the following to your ceph.conf::

    enable experimental unrecoverable data corrupting features = btrfs

  The code is mature and unlikely to change, but we are only
  continuing to test the Jewel stable branch against btrfs.  We
  recommend moving these OSDs to FileStore with XFS or BlueStore.
* The ``ruleset-*`` properties for the erasure code profiles have been
  renamed to ``crush-*`` to move away from the obsolete 'ruleset'
  term and to be more clear about their purpose.  There is also a new
  optional ``crush-device-class`` property to specify a CRUSH device
  class to use for the erasure coded pool.  Existing erasure code
  profiles will be converted automatically when upgrade completes
  (when the ``ceph osd require-osd-release luminous`` command is run)
  but any provisioning tools that create erasure coded pools may need
  to be updated.
* The structure of the XML output for ``osd crush tree`` has changed
  slightly to better match the ``osd tree`` output.  The top level
  structure is now ``nodes`` instead of ``crush_map_roots``.
* When assigning a network to the public network and not to
  the cluster network the network specification of the public
  network will be used for the cluster network as well.
  In older versions this would lead to cluster services
  being bound to 0.0.0.0:<port>, thus making the
  cluster service even more publicly available than the
  public services. When only specifying a cluster network it
  will still result in the public services binding to 0.0.0.0.

* In previous versions, if a client sent an op to the wrong OSD, the OSD
  would reply with ENXIO.  The rationale here is that the client or OSD is
  clearly buggy and we want to surface the error as clearly as possible.
  We now only send the ENXIO reply if the osd_enxio_on_misdirected_op option
  is enabled (it's off by default).  This means that a VM using librbd that
  previously would have gotten an EIO and gone read-only will now see a
  blocked/hung IO instead.

* The "journaler allow split entries" config setting has been removed.

* The 'mon_warn_osd_usage_min_max_delta' config option has been
  removed and the associated health warning has been disabled because
  it does not address clusters undergoing recovery or CRUSH rules that do
  not target all devices in the cluster.

* Added new configuration "public bind addr" to support dynamic
  environments like Kubernetes. When set the Ceph MON daemon could
  bind locally to an IP address and advertise a different IP address
  ``public addr`` on the network.

* The crush ``choose_args`` encoding has been changed to make it
  architecture-independent. If you deployed Luminous dev releases or
  12.1.0 rc release and made use of the CRUSH choose_args feature, you
  need to remove all choose_args mappings from your CRUSH map before
  starting the upgrade.


- *librados*:

  * Some variants of the omap_get_keys and omap_get_vals librados
    functions have been deprecated in favor of omap_get_vals2 and
    omap_get_keys2.  The new methods include an output argument
    indicating whether there are additional keys left to fetch.
    Previously this had to be inferred from the requested key count vs
    the number of keys returned, but this breaks with new OSD-side
    limits on the number of keys or bytes that can be returned by a
    single omap request.  These limits were introduced by kraken but
    are effectively disabled by default (by setting a very large limit
    of 1 GB) because users of the newly deprecated interface cannot
    tell whether they should fetch more keys or not.  In the case of
    the standalone calls in the C++ interface
    (IoCtx::get_omap_{keys,vals}), librados has been updated to loop on
    the client side to provide a correct result via multiple calls to
    the OSD.  In the case of the methods used for building
    multi-operation transactions, however, client-side looping is not
    practical, and the methods have been deprecated.  Note that use of
    either the IoCtx methods on older librados versions or the
    deprecated methods on any version of librados will lead to
    incomplete results if/when the new OSD limits are enabled.

  * The original librados rados_objects_list_open (C) and objects_begin
    (C++) object listing API, deprecated in Hammer, has finally been
    removed.  Users of this interface must update their software to use
    either the rados_nobjects_list_open (C) and nobjects_begin (C++) API or
    the new rados_object_list_begin (C) and object_list_begin (C++) API
    before updating the client-side librados library to Luminous.
    Object enumeration (via any API) with the latest librados version
    and pre-Hammer OSDs is no longer supported.  Note that no in-tree
    Ceph services rely on object enumeration via the deprecated APIs, so
    only external librados users might be affected.
    The newest (and recommended) rados_object_list_begin (C) and
    object_list_begin (C++) API is only usable on clusters with the
    SORTBITWISE flag enabled (Jewel and later).  (Note that this flag is
    required to be set before upgrading beyond Jewel.)

- *CephFS*:

  * When configuring ceph-fuse mounts in /etc/fstab, a new syntax is
    available that uses "ceph.<arg>=<val>" in the options column, instead
    of putting configuration in the device column.  The old style syntax
    still works.  See the documentation page "Mount CephFS in your
    file systems table" for details.
  * CephFS clients without the 'p' flag in their authentication capability
    string will no longer be able to set quotas or any layout fields.  This
    flag previously only restricted modification of the pool and namespace
    fields in layouts.
  * CephFS will generate a health warning if you have fewer standby daemons
    than it thinks you wanted.  By default this will be 1 if you ever had
    a standby, and 0 if you did not.  You can customize this using
    ``ceph fs set <fs> standby_count_wanted <number>``.  Setting it
    to zero will effectively disable the health check.
  * The "ceph mds tell ..." command has been removed.  It is superseded
    by "ceph tell mds.<id> ..."
  * The ``apply`` mode of cephfs-journal-tool has been removed
