本文档适用于 Ceph 开发版本。

Jewel

Jewel 是 Ceph 的第 10 个稳定版本。它以珠宝乌贼（Histioteuthis reversa）命名。

v10.2.11 Jewel

此版本发布带来了一些重要的错误修复，并有一些重要的安全修复。预计这是最后一个 Jewel 版本。我们建议所有 Jewel 10.2.x 用户升级。

显著变化

  • CVE 2018-1128: 认证：cephx 作者izer 易受重放攻击 (问题#24836， Sage Weil)

  • CVE 2018-1129: 认证：cephx 签名检查较弱 (问题#24837， Sage Weil)

  • CVE 2018-10861: mon：池操作认证检查不正确 (问题#24838， Jason Dillaman)

  • RBD C API 的 rbd_discard 方法和 C++ API 的 Image::discard 方法现在强制执行最大长度为 2GB。此限制防止结果代码溢出。

  • 新的 OSD 现在默认使用 rocksdb 而不是 leveldb 来存储 omap 数据。omap 由 RGW 桶索引和 CephFS 目录使用，当单个 leveldb 在高写入或删除工作负载下增长到 10GB 时，当 leveldb 的单线程压缩无法跟上时，可能会导致高延迟。rocksdb 支持多线程压缩，这避免了这个问题。

  • CephFS 客户端现在在启动期间捕获清除 dentries 的失败，并拒绝启动，因为可能会出现一致性和不可修剪缓存问题。新的选项 client_die_on_failed_dentry_invalidate（默认：true）可以关闭，以允许客户端继续（危险！）。

  • 在 10.2.10 及更早版本中，密钥环 caps 没有检查有效性，因此 caps 字符串可以是任何内容。从 10.2.11 开始，caps 字符串将进行验证，向例如“ceph auth add”提供无效的密钥环将导致错误。

v10.2.8 Jewel

This point release brought a number of important bugfixes in all major components of Ceph. However, it also introduced a regression that could cause MDS damage, and a new release, v10.2.9, was published to address this. Therefore, Jewel users should not upgrade to this version - instead, we recommend upgrading directly to v10.2.9.

OSD Removal Caveat

There was a bug introduced in Jewel (#19119) that broke the mapping behavior when an “out” OSD that still existed in the CRUSH map was removed with ‘osd rm’. This could result in ‘misdirected op’ and other errors. The bug is now fixed, but the fix itself introduces the same risk because the behavior may vary between clients and OSDs. To avoid problems, please ensure that all OSDs are removed from the CRUSH map before deleting them. That is, be sure to do:

ceph osd crush rm osd.123

before:

ceph osd rm osd.123

Snap Trimmer Improvements

This release greatly improves control and throttling of the snap trimmer. It introduces the “osd max trimming pgs” option (defaulting to 2), which limits how many PGs on an OSD can be trimming snapshots at a time. And it restores the safe use of the “osd snap trim sleep” option, which defaults to 0 but otherwise adds the given number of seconds in delay between every dispatch of trim operations to the underlying system.

OSDs No Longer Send ENXIO by Default

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.

Upgrading from hammer

When the last hammer OSD in a cluster containing jewel MONs is upgraded to jewel, as of 10.2.4 the jewel MONs will issue this warning: “all OSDs are running jewel or later but the ‘require_jewel_osds’ osdmap flag is not set” and change the cluster health status to HEALTH_WARN.

This is a signal for the admin to do “ceph osd set require_jewel_osds” - by doing this, the upgrade path is complete and no more pre-Jewel OSDs may be added to the cluster.

v10.2.0 Jewel

This major release of Ceph is the foundation for the next

Major Changes from Infernalis

  • CephFS:

    • This is the first release in which CephFS is declared stable!

    • The repair and disaster recovery tools are now feature-complete.

    • A new cephfs-volume-manager module is included that provides a

    • There is now experimental support for multiple CephFS file systems

  • RGW:

    • The multisite feature has been almost completely rearchitected and

    • You can now access radosgw buckets via NFS (experimental).

    • The AWS4 authentication protocol is now supported.

    • There is now support for S3 request payer buckets.

    • The new multitenancy infrastructure improves compatibility with

    • The OpenStack Keystone v3 API is now supported. There are a range

  • RBD:

    • There is new support for mirroring (asynchronous replication) of RBD images across clusters. This is implemented as a per-RBD image journal that can be streamed across a WAN to another site, and a new rbd-mirror daemon that performs the cross-cluster replication.

    • The exclusive-lock, object-map, fast-diff, and journaling features can be enabled or disabled dynamically. The deep-flatten features can be disabled dynamically but not re-enabled.

    • The RBD CLI has been rewritten to provide command-specific help and full bash completion support.

    • RBD snapshots can now be renamed.

  • RADOS:

    • BlueStore, a new OSD backend, is included as an experimental feature. The plan is for it to become the default backend in the K or L release.

    • The OSD now persists scrub results and provides a librados API to query results in detail.

    • We have revised our documentation to recommend against using ext4 as the underlying filesystem for Ceph OSD daemons due to problems supporting our long object name handling.

Major Changes from Hammer

  • General:

    • Ceph daemons are now managed via systemd (with the exception of Ubuntu Trusty, which still uses upstart).

    • Ceph daemons run as ‘ceph’ user instead of ‘root’.

    • On Red Hat distros, there is also an SELinux policy.

  • RADOS:

    • The RADOS cache tier can now proxy write operations to the base tier, allowing writes to be handled without forcing migration of an object into the cache.

    • The SHEC erasure coding support is no longer flagged as experimental. SHEC trades some additional storage space for faster repair.

    • There is now a unified queue (and thus prioritization) of client IO, recovery, scrubbing, and snapshot trimming.

    • There have been many improvements to low-level repair tooling (ceph-objectstore-tool).

    • The internal ObjectStore API has been significantly cleaned up in order to facilitate new storage backends like BlueStore.

  • RGW:

    • The Swift API now supports object expiration.

    • There are many Swift API compatibility improvements.

  • RBD:

    • Therbd du command shows actual usage (quickly, when object-map is enabled).

    • The object-map feature has seen many stability improvements.

    • The object-map and exclusive-lock features can be enabled or disabled dynamically.

    • You can now store user metadata and set persistent librbd options associated with individual images.

    • The new deep-flatten features allow flattening of a clone and all of its snapshots. (Previously snapshots could not be flattened.)

    • The export-diff command is now faster (it uses aio). There is also a new fast-diff feature.

    • The --size argument can be specified with a suffix for units (e.g., --size 64G搜索）。

    • There is a new rbd status command that, for now, shows who has the image open/mapped.

  • CephFS:

    • You can now rename snapshots.

    • There have been ongoing improvements around administration, diagnostics, and the check and repair tools.

    • The caching and revocation of client cache state due to unused inodes has been dramatically improved.

    • The ceph-fuse client behaves better on 32-bit hosts.

Distro compatibility

Starting with Infernalis, we have dropped support for many older distributions so that we can move to a newer compiler toolchain (e.g., C++11). Although it is still possible to build Ceph on older distributions by installing backported development tools, we are not building and publishing release packages for ceph.com.

We now build packages for the following distributions and architectures:

  • x86_64:

    • CentOS 7.x. We have dropped support for CentOS 6 (and other RHEL 6 derivatives, like Scientific Linux 6).

    • Debian Jessie 8.x. Debian Wheezy 7.x’s g++ has incomplete support for C++11 (and no systemd).

    • Ubuntu Xenial 16.04 and Trusty 14.04. Ubuntu Precise 12.04 is no longer supported.

    • Fedora 22 or later.

  • aarch64 / arm64:

    • Ubuntu Xenial 16.04.

Upgrading from Infernalis or Hammer

  • We now recommend against using ext4 as the underlying file system for Ceph OSDs, especially when RGW or other users of long RADOS object names are used. For more information about why, please see Filesystem Recommendations.

    If you have an existing cluster that uses ext4 for the OSDs but uses only RBD and/or CephFS, then the ext4 limitations will not affect you. Before upgrading, be sure add the following to ceph.conf to allow the OSDs to start:

    osd max object name len = 256
osd max object namespace len = 64

    Keep in mind that if you set these lower object name limits and later decide to use RGW on this cluster, it will have problems storing S3/Swift objects with long names. This startup check can also be disabled via the below option, although this is not recommended:

    osd check max object name len on startup = false

  • There are no major compatibility changes since Infernalis. Simply upgrading the daemons on each host and restarting all daemons is sufficient.

  • The rbd CLI no longer accepts the deprecated ‘--image-features’ option during create, import, and clone operations. The ‘--image-feature’ option should be used instead.

  • The rbd legacy image format (version 1) is deprecated with the Jewel release. Attempting to create a new version 1 RBD image will result in a warning. Future releases of Ceph will remove support for version 1 RBD images.

  • The ‘send_pg_creates’ and ‘map_pg_creates’ mon CLI commands are obsolete and no longer supported.

  • A new configure option ‘mon_election_timeout’ is added to specifically limit max waiting time of monitor election process, which was previously restricted by ‘mon_lease’.

  • CephFS filesystems created using versions older than Firefly (0.80) must use the new ‘cephfs-data-scan tmap_upgrade’ command after upgrading to Jewel. See ‘Upgrading’ in the CephFS documentation for more information.

  • The ‘ceph mds setmap’ command has been removed.

  • The default RBD image features for new images have been updated to enable the following: exclusive lock, object map, fast-diff, and deep-flatten. These features are not currently supported by the RBD kernel driver nor older RBD clients. They can be disabled on a per-image basis via the RBD CLI, or the default features can be updated to the pre-Jewel setting by adding the following to the client section of the Ceph configuration file:

    rbd default features = 1

  • The rbd legacy image format (version 1) is deprecated with the Jewel release.

  • After upgrading, users should set the ‘sortbitwise’ flag to enable the new internal object sort order:

    ceph osd set sortbitwise

    This flag is important for the new object enumeration API and for new backends like BlueStore.

  • The rbd CLI no longer permits creating images and snapshots with potentially ambiguous names (e.g. the ‘/’ and ‘@’ characters are disallowed). The validation can be temporarily disabled by adding “--rbd-validate-names=false” to the rbd CLI when creating an image or snapshot. It can also be disabled by adding the following to the client section of the Ceph configuration file:

    rbd validate names = false

Upgrading from Hammer

  • All cluster nodes must first upgrade to Hammer v0.94.4 or a later v0.94.z release; only then is it possible to upgrade to Jewel 10.2.z.

  • For all distributions that support systemd (CentOS 7, Fedora, Debian Jessie 8.x, OpenSUSE), ceph daemons are now managed using native systemd files instead of the legacy sysvinit scripts. For example:

    systemctl start ceph.target       # start all daemons
systemctl status ceph-osd@12      # check status of osd.12

    The main notable distro that is not yet using systemd is Ubuntu trusty 14.04. (The next Ubuntu LTS, 16.04, will use systemd instead of upstart.)

  • Ceph daemons now run as user and group ceph by default. The ceph user has a static UID assigned by Fedora and Debian (also used by derivative distributions like RHEL/CentOS and Ubuntu). On SUSE the same UID/GID as in Fedora and Debian will be used, provided it is not already assigned. In the unlikely event the preferred UID or GID is assigned to a different user/group, ceph will get a dynamically assigned UID/GID.

    If your systems already have a ceph user, upgrading the package will cause problems. We suggest you first remove or rename the existing ‘ceph’ user and ‘ceph’ group before upgrading.

    When upgrading, administrators have two options:

    1. Add the following line to ceph.conf on all hosts:

      setuser match path = /var/lib/ceph/$type/$cluster-$id

      This will make the Ceph daemons run as root (i.e., not drop privileges and switch to user ceph) if the daemon’s data directory is still owned by root. Newly deployed daemons will be created with data owned by user ceph and will run with reduced privileges, but upgraded daemons will continue to run as root.

    2. Fix the data ownership during the upgrade. This is the preferred option, but it is more work and can be very time consuming. The process for each host is to:

      1. Upgrade the ceph package. This creates the ceph user and group. For example:

        ceph-deploy install --stable jewel HOST

      2. Stop the daemon(s):

        service ceph stop           # fedora, centos, rhel, debian
stop ceph-all               # ubuntu

      3. Fix the ownership:

        chown -R ceph:ceph /var/lib/ceph
chown -R ceph:ceph /var/log/ceph

      4. Restart the daemon(s):

        start ceph-all                # ubuntu
systemctl start ceph.target   # debian, centos, fedora, rhel

      Alternatively, the same process can be done with a single daemon type, for example by stopping only monitors and chowning only /var/lib/ceph/mon.

  • The on-disk format for the experimental KeyValueStore OSD backend has changed. You will need to remove any OSDs using that backend before you upgrade any test clusters that use it.

  • When a pool quota is reached, librados operations now block indefinitely, the same way they do when the cluster fills up. (Previously they would return -ENOSPC.) By default, a full cluster or pool will now block. If your librados application can handle ENOSPC or EDQUOT errors gracefully, you can get error returns instead by using the new librados OPERATION_FULL_TRY flag.

  • The return code for librbd’s rbd_aio_read and Image::aio_read API methods no longer returns the number of bytes read upon success. Instead, it returns 0 upon success and a negative value upon failure.

  • ‘ceph scrub’, ‘ceph compact’ and ‘ceph sync force’ are now DEPRECATED. Users should instead use ‘ceph mon scrub’, ‘ceph mon compact’ and ‘ceph mon sync force’.

  • ‘ceph mon_metadata’ should now be used as ‘ceph mon metadata’. There is no need to deprecate this command (same major release since it was first introduced).

  • The--dump-json option of “osdmaptool” is replaced by --dump json.

  • The commands of “pg ls-by-{pool,primary,osd}” and “pg ls” now take “recovering” instead of “recovery”, to include the recovering pgs in the listed pgs.

Upgrading from Firefly

Upgrading directly from Firefly v0.80.z is not recommended. It is possible to do a direct upgrade, but not without downtime, as all OSDs must be stopped, upgraded, and then restarted. We recommend that clusters be first upgraded to Hammer v0.94.6 or a later v0.94.z release; only then is it possible to upgrade to Jewel 10.2.z for an online upgrade (see below).

To do an offline upgrade directly from Firefly, all Firefly OSDs must be stopped and marked down before any Jewel OSDs will be allowed to start up. This fencing is enforced by the Jewel monitor, so you should use an upgrade procedure like:

  1. Upgrade Ceph on monitor hosts

  2. Restart all ceph-mon daemons

  3. Set noout::

    ceph osd set noout

  4. Upgrade Ceph on all OSD hosts

  5. Stop all ceph-osd daemons

  6. Mark all OSDs down with something like::

    ceph osd down seq 0 1000

  7. Start all ceph-osd daemons

  8. Let the cluster settle and then unset noout::

    ceph osd unset noout

  9. Upgrade and restart any remaining daemons (ceph-mds, radosgw)
