v12.1.1 Luminous RC released

This is the second release candidate for Luminous, the next long term stable
release. Please note that this is still a Release Candidate and not the final Luminous release.

Ceph Luminous (v12.2.0) will be the foundation for the next 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.


  • General:

    • Ceph now has a simple, built-in web-based 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.
      • BlueStore supports full data and metadata checksums of all data stored by Ceph.
      • BlueStore supports inline compression using zlib, snappy, or LZ4. (Ceph also supports zstd for RGW compression but zstd is not recommended for BlueStore for performance reasons.)
    • Erasure coded pools now have full support for overwrites, allowing them to be used with RBD and CephFS. Read more about EC overwrites.

    • The configuration option “osd pool erasure code stripe width” has been replaced by “osd pool erasure code stripe unit”, and given the ability to be overridden by the erasure code profile setting “stripe_unit”.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 “Erasure Code Profiles” in the documentation.

    • 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 newmon_osd_err_op_age_ratio that is a expressed as a multitple ofmon_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.

    • 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. The API is still experimental and somewhat limited but will form the basis for API-based management of Ceph going forward. FIXME DOCS
      • The status ceph-mgr module is enabled by default, and initially provides two commands: ceph tell mgr osd status and ceph tell mgr fs status. These are high level colorized views to complement the existing CLI.
    • 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 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. FIXME DOCS

    • You can now optimize CRUSH weights can now be optimized to maintain a near-perfect distribution of data across OSDs. FIXME DOCS

    • There is also a new upmap exception mechanism that allows individual PGs to be moved around to achieve a perfect distribution (this requires luminous clients). FIXME DOCS

    • 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 is now available. FIXME DOCS

    • 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 that is more robust. FIXME DOCS

    • You can query the supported features and (apparent) releases of all connected daemons and clients with ceph features. FIXME DOCS

    • 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. FIXME DOCS

    • 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.)

    • 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.
  • 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. 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.
    • 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.
    • RGW has consolidated the several metadata index pools via the use of rados namespaces.
  • 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.
    • 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 demotecommands to batch promote/demote all mirrored images within a pool.
    • Mirroring now optionally supports a configurable replication delay via the rbd mirroringreplay 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
  • 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.
  • Miscellaneous:

    • Release packages are now being built for Debian Stretch. The distributions we build for now includes:

      • 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)

      Note that QA is limited to CentOS and Ubuntu (xenial and trusty).

    • CLI changes:

      • The ceph -s or ceph status command has a fresh look.
      • ceph {osd,mds,mon} versions summarizes versions of running daemons.
      • ceph {osd,mds,mon} count-metadata <property> similarly tabulates any other daemon metadata visible via the ceph {osd,mds,mon} metadatacommands.
      • ceph features summarizes features and releases of connected clients and daemons.
      • ceph osd require-osd-release <release> replaces the oldrequire_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 (FIXME DOCS).
      • 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, nodown, noin, and noup flags to be applied to specific OSDs.
      • 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 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 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 class {create,rm,ls,rename} manage the new CRUSH device class feature. ceph crush set-device-class <class> <osd>[<osd>...] will set the class for particular devices.
      • ceph osd crush rule create-replicated replaces the old ceph osdcrush 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. cephmon feature set will set an optional feature (none of these exist yet).
      • ceph tell <daemon> help will now return a usage summary.


  • 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.


  1. Ensure that the sortbitwise flag is enabled:

    # ceph osd set sortbitwise
  2. Make sure your cluster is stable and healthy (no down or recoverying OSDs). (Optional, but recommended.)

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

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

    # ceph osd set noout
  5. 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

    Verify the monitor upgrade is complete once all monitors are up by looking for the luminousfeature 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]
  6. Add or restart ceph-mgr daemons. If you are upgrading from kraken, upgrade packages and restart ceph-mgr daemons with:

    # systemctl restart

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

    # systemctl restart

    You can monitor the progress of the OSD upgrades with the new ceph osd versionscommand.:

    # ceph osd versions
       "ceph version 12.2.0 (...) luminous (stable)": 12,
       "ceph version 10.2.6 (...)": 3,
  8. Upgrade all CephFS daemons by upgrading packages and restarting daemons on all hosts.:

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

    # systemctl restart
  10. Complete the upgrade by disallowing pre-luminous OSDs:

    # ceph osd require-osd-release luminous

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

    # ceph osd unset noout
  11. Verify the cluster is healthy with ceph health.


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


  • 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 follwing 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 (1) 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.

  • 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<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

  • 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.

  • 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 superceded by “ceph tell mds.<id> …”


  • 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.
  • The ‘ceph health’ structured output (JSON or XML) no longer contains a ‘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.
  • The ‘apply’ mode of cephfs-journal-tool has been removed
  • 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.
