|
|
|
|
* The RGW policy parser now rejects unknown principals by default. If you are
|
|
|
|
|
mirroring policies between RGW and AWS, you may wish to set
|
|
|
|
|
"rgw policy reject invalid principals" to "false". This affects only newly set
|
|
|
|
|
policies, not policies that are already in place.
|
2022-04-05 21:20:22 +00:00
|
|
|
|
* RGW's default backend for `rgw_enable_ops_log` changed from RADOS to file.
|
|
|
|
|
The default value of `rgw_ops_log_rados` is now false, and `rgw_ops_log_file_path`
|
|
|
|
|
defaults to "/var/log/ceph/ops-log-$cluster-$name.log".
|
2022-04-17 23:40:24 +00:00
|
|
|
|
* The SPDK backend for BlueStore is now able to connect to an NVMeoF target.
|
|
|
|
|
Please note that this is not an officially supported feature.
|
2022-04-10 01:23:59 +00:00
|
|
|
|
* RGW's pubsub interface now returns boolean fields using bool. Before this change,
|
|
|
|
|
`/topics/<topic-name>` returns "stored_secret" and "persistent" using a string
|
|
|
|
|
of "true" or "false" with quotes around them. After this change, these fields
|
|
|
|
|
are returned without quotes so they can be decoded as boolean values in JSON.
|
|
|
|
|
The same applies to the `is_truncated` field returned by `/subscriptions/<sub-name>`.
|
|
|
|
|
* RGW's response of `Action=GetTopicAttributes&TopicArn=<topic-arn>` REST API now
|
|
|
|
|
returns `HasStoredSecret` and `Persistent` as boolean in the JSON string
|
|
|
|
|
encoded in `Attributes/EndPoint`.
|
|
|
|
|
* All boolean fields previously rendered as string by `rgw-admin` command when
|
|
|
|
|
the JSON format is used are now rendered as boolean. If your scripts/tools
|
|
|
|
|
relies on this behavior, please update them accordingly. The impacted field names
|
|
|
|
|
are:
|
|
|

|
|
|
|
|

2022-05-05 15:36:34 +00:00
|
|
|
|
* RGW: The beast frontend's HTTP access log line uses a new debug_rgw_access
|
|
|
|
|
configurable. This has the same defaults as debug_rgw, but can now be controlled
|
|
|
|
|
independently.
|
2022-08-12 11:55:01 +00:00
|
|
|
|
* RBD: The semantics of compare-and-write C++ API (`Image::compare_and_write`
|
|
|
|
|
and `Image::aio_compare_and_write` methods) now match those of C API. Both
|
|
|
|
|
compare and write steps operate only on `len` bytes even if the respective
|
|
|
|
|
buffers are larger. The previous behavior of comparing up to the size of
|
|
|
|
|
the compare buffer was prone to subtle breakage upon straddling a stripe
|
|
|
|
|
unit boundary.
|
|
|
|
|
* RBD: compare-and-write operation is no longer limited to 512-byte sectors.
|
|
|
|
|
Assuming proper alignment, it now allows operating on stripe units (4M by
|
|
|
|
|
default).
|
2022-10-06 10:36:00 +00:00
|
|
|
|
* RBD: New `rbd_aio_compare_and_writev` API method to support scatter/gather
|
|
|
|
|
on both compare and write buffers. This compliments existing `rbd_aio_readv`
|
|
|
|
|
and `rbd_aio_writev` methods.
|
2022-07-20 01:37:25 +00:00
|
|
|
|
* The 'AT_NO_ATTR_SYNC' macro is deprecated, please use the standard 'AT_STATX_DONT_SYNC'
|
|
|
|
|
macro. The 'AT_NO_ATTR_SYNC' macro will be removed in the future.
|
2022-08-23 19:50:48 +00:00
|
|
|
|
* Trimming of PGLog dups is now controlled by the size instead of the version.
|
|
|
|
|
This fixes the PGLog inflation issue that was happening when the on-line
|
|
|
|
|
(in OSD) trimming got jammed after a PG split operation. Also, a new off-line
|
|
|
|
|
mechanism has been added: `ceph-objectstore-tool` got `trim-pg-log-dups` op
|
|
|
|
|
that targets situations where OSD is unable to boot due to those inflated dups.
|
|
|
|
|
If that is the case, in OSD logs the "You can be hit by THE DUPS BUG" warning
|
|
|
|
|
will be visible.

|
|
|
|
* RBD: `rbd device unmap` command gained `--namespace` option. Support for
|
|
|
|
|
namespaces was added to RBD in Nautilus 14.2.0 and it has been possible to
|
|
|
|
|
map and unmap images in namespaces using the `image-spec` syntax since then
|
|
|
|
|
but the corresponding option available in most other commands was missing.
|
2022-10-24 16:40:07 +00:00
|
|
|
|
* RGW: Compression is now supported for objects uploaded with Server-Side Encryption.
|
|
|
|
|
When both are enabled, compression is applied before encryption.
|
2022-12-01 15:43:35 +00:00
|
|
|
|
* RGW: the "pubsub" functionality for storing bucket notifications inside Ceph
|
|
|
|
|
is removed. Together with it, the "pubsub" zone should not be used anymore.
|
|
|
|
|
The REST operations, as well as radosgw-admin commands for manipulating
|
|
|
|
|
subscriptions, as well as fetching and acking the notifications are removed
|
|
|
|
|
as well.
|
|
|
|
|
In case that the endpoint to which the notifications are sent maybe down or
|
|
|
|
|
disconnected, it is recommended to use persistent notifications to guarantee
|
|
|
|
|
the delivery of the notifications. In case the system that consumes the
|
|
|
|
|
notifications needs to pull them (instead of the notifications be pushed
|
|
|
|
|
to it), an external message bus (e.g. rabbitmq, Kafka) should be used for
|
|
|
|
|
that purpose.
|
2022-11-25 14:15:27 +00:00
|
|
|
|
* RGW: The serialized format of notification and topics has changed, so that
|
|
|
|
|
new/updated topics will be unreadable by old RGWs. We recommend completing
|
|
|
|
|
the RGW upgrades before creating or modifying any notification topics.
|
2022-11-14 12:24:00 +00:00
|
|
|
|
* RBD: Trailing newline in passphrase files (`<passphrase-file>` argument in
|
|
|
|
|
`rbd encryption format` command and `--encryption-passphrase-file` option
|
|
|
|
|
in other commands) is no longer stripped.
|
2022-10-28 10:42:14 +00:00
|
|
|
|
* RBD: Support for layered client-side encryption is added. Cloned images
|
|
|
|
|
can now be encrypted each with its own encryption format and passphrase,
|
|
|
|
|
potentially different from that of the parent image. The efficient
|
|
|
|
|
copy-on-write semantics intrinsic to unformatted (regular) cloned images
|
|
|
|
|
are retained.
|
2022-07-15 09:13:37 +00:00
|
|
|
|
* CEPHFS: Rename the `mds_max_retries_on_remount_failure` option to
|
|
|
|
|
`client_max_retries_on_remount_failure` and move it from mds.yaml.in to
|
|
|
|
|
mds-client.yaml.in because this option was only used by MDS client from its
|
|
|
|
|
birth.
|
2022-07-19 21:39:02 +00:00
|
|
|
|
* The `perf dump` and `perf schema` commands are deprecated in favor of new
|
|
|
|
|
`counter dump` and `counter schema` commands. These new commands add support
|
|
|
|
|
for labeled perf counters and also emit existing unlabeled perf counters. Some
|
2023-04-06 10:32:11 +00:00
|
|
|
|
unlabeled perf counters became labeled in this release, with more to follow in
|
|
|
|
|
future releases; such converted perf counters are no longer emitted by the
|
|
|
|
|
`perf dump` and `perf schema` commands.
|
2023-02-06 16:56:00 +00:00
|
|
|
|
* `ceph mgr dump` command now outputs `last_failure_osd_epoch` and
|
|
|
|
|
`active_clients` fields at the top level. Previously, these fields were
|
|
|
|
|
output under `always_on_modules` field.
|
2023-01-30 07:21:54 +00:00
|
|
|
|
* `ceph mgr dump` command now displays the name of the mgr module that
|
|
|
|
|
registered a RADOS client in the `name` field added to elements of the
|
|
|
|
|
`active_clients` array. Previously, only the address of a module's RADOS
|
|
|
|
|
client was shown in the `active_clients` array.
|
2023-04-06 10:32:11 +00:00
|
|
|
|
* RBD: All rbd-mirror daemon perf counters became labeled and as such are now
|
|
|
|
|
emitted only by the new `counter dump` and `counter schema` commands. As part
|
|
|
|
|
of the conversion, many also got renamed to better disambiguate journal-based
|
|
|
|
|
and snapshot-based mirroring.
|
2023-03-30 11:58:20 +00:00
|
|
|
|
* RBD: list-watchers C++ API (`Image::list_watchers`) now clears the passed
|
|
|
|
|
`std::list` before potentially appending to it, aligning with the semantics
|
|
|
|
|
of the corresponding C API (`rbd_watchers_list`).
|
2023-04-12 12:00:31 +00:00
|
|
|
|
* Telemetry: Users who are opted-in to telemetry can also opt-in to
|
|
|
|
|
participating in a leaderboard in the telemetry public
|
|
|
|
|
dashboards (https://telemetry-public.ceph.com/). Users can now also add a
|
|
|
|
|
description of the cluster to publicly appear in the leaderboard.
|
|
|
|

See a sample report with `ceph telemetry preview`.
|
|
|
|
|
Opt-in to telemetry with `ceph telemetry on`.
|
|
|
|
|
Opt-in to the leaderboard with
|
|
|
|
|
`ceph config set mgr mgr/telemetry/leaderboard true`.
|
|
|
|
|
Add leaderboard description with:
|
|
|
|
|
`ceph config set mgr mgr/telemetry/leaderboard_description ‘Cluster description’`.

* CEPHFS: After recovering a Ceph File System post following the disaster recovery
|
|
|
|
|
procedure, the recovered files under `lost+found` directory can now be deleted.

* The "BlueStore zero block detection" feature (first introduced to Quincy in
|
|
|
|
|
https://github.com/ceph/ceph/pull/43337) has been turned off by default with a
|
|
|
|
|
new global configuration called `bluestore_zero_block_detection`. This feature,
|
|
|
|
|
intended for large-scale synthetic testing, does not interact well with some RBD
|
|
|
|
|
and CephFS features. Any side effects experienced in previous Quincy versions
|
|
|
|
|
would no longer occur, provided that the configuration remains set to false.

* OSD: The issue of high CPU utilization during recovery/backfill operations
|
|
|
|
|
has been fixed. For more details, see: https://tracker.ceph.com/issues/56530.

>=15.2.17
|

|
|
|
* OSD: Octopus modified the SnapMapper key format from
|
|
|
|
|
<LEGACY_MAPPING_PREFIX><snapid>_<shardid>_<hobject_t::to_str()>
|
|
|
|
|
to
|
|
|
|
|
<MAPPING_PREFIX><pool>_<snapid>_<shardid>_<hobject_t::to_str()>
|
|
|
|
|
When this change was introduced, 94ebe0e also introduced a conversion
|
|
|
|
|
with a crucial bug which essentially destroyed legacy keys by mapping them
|
|
|
|
|
to
|
|
|
|
|
<MAPPING_PREFIX><poolid>_<snapid>_
|
|
|
|
|
without the object-unique suffix. The conversion is fixed in this release.

|
|
|
* Cephadm may now be configured to carry out CephFS MDS upgrades without
|
|
|
|
|
reducing ``max_mds`` to 1. Previously, Cephadm would reduce ``max_mds`` to 1 to
|
|
|
|
|
avoid having two active MDS modifying on-disk structures with new versions,
|
|
|
|
|
communicating cross-version-incompatible messages, or other potential
|
|
|
|
|
incompatibilities. This could be disruptive for large-scale CephFS deployments
|
|
|
|
|
because the cluster cannot easily reduce active MDS daemons to 1.

* Introduced a new file system flag `refuse_client_session` that can be set using the
|
|
|
|
|
`fs set` command. This flag allows blocking any incoming session
|
|
|
|
|
request from client(s). This can be useful during some recovery situations
|
|
|
|
|
where it's desirable to bring MDS up but have no client workload.

* New MDSMap field `max_xattr_size` which can be set using the `fs set` command.
|
|
|
|
|
This MDSMap field allows to configure the maximum size allowed for the full
|
|
|
|
|
key/value set for a filesystem extended attributes. It effectively replaces
|
|
|
|
|
the old per-MDS `max_xattr_pairs_size` setting, which is now dropped.
