We're happy to announce the 11th backport release in the Pacific series.
We recommend users to update to this release. For detailed release
notes with links & changelog please refer to the official blog entry
at https://ceph.io/en/news/blog/2023/v16-2-11-pacific-released
Notable Changes
---------------
* Cephfs: 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.
* 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.
Relevant tracker: https://tracker.ceph.com/issues/53729
* 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.
Getting Ceph

* Git at git://github.com/ceph/ceph.git
* Tarball at https://download.ceph.com/tarballs/ceph-16.2.11.tar.gz

Hi everyone,
From November into January, we experienced a series of outages with the
Ceph Community Infrastructure and its services:
-
Mailing lists
-
https://lists.ceph.io
-
Sepia (testing infrastructure)
-
https://wiki.sepia.ceph.com
-
https://pulpito.ceph.com
-
https://chacra.ceph.com
-
https://shaman.ceph.com
-
VPN to access testing services
-
Etherpad
-
https://pad.ceph.com
-
Images:
-
https://quay.ceph.io
-
Git mirror
-
https://git.ceph.com
-
https://ceph.io
-
Telemetry <https://telemetry-public.ceph.com/>
These services are now mostly restored, but we did experience some data
loss, notably in our mailing lists. We have restored them from backups, but
subscription changes after July 2021 need to be repeated. If you subscribed
or unsubscribed since then, please check your settings with the appropriate
list at https://lists.ceph.io. If your posts to our mailing lists are now
needing approval, that is also an indication that you need to re-subscribe
to the appropriate lists.
Keep an eye out for emails with subject lines such as “Your message to
ceph-users(a)ceph.io awaits moderator approval”.
When the community infrastructure was first created in late 2014, the VM
cluster management software selected by the team came with the benefit of
being widely entrenched and familiar to the lab administrators but didn't
support Ceph as a storage backend at the time. As services grew, we relied
more and more on its legacy storage solution, which was never migrated to
Ceph. Over the last few months, this legacy storage solution had several
instances of silent data corruption, rendering the VMs unbootable, taking
down various services, and requiring restoration from backups in many cases.
We are moving these services to a more reliable, mostly container-based,
infrastructure backed by Ceph, and planning for longer-term improvements to
monitoring, backups, deployment, and other pieces of the project
infrastructure.
This event highlights the need to better support the infrastructure. A
handful of contributors have stepped up to restore these services, but we
need an invested team focused.
If you or your company is looking for a great way to contribute to the Ceph
community, this could be your opportunity. Please contact council(a)ceph.io
if you can provide time to contribute to the Ceph Community Infrastructure
and would like to join the team. You can also join the upstream #sepia
slack channel to participate in these discussions using this link:
https://join.slack.com/t/ceph-storage/shared_invite/zt-1n1eh6po5-PF9sokUSoo…
Unfortunately, these events have slowed down our upstream development and
releases. We are currently working on publishing the next Pacific point
release. The development freeze and release deadline for the Reef release
will likely be pushed out, and more discussions to follow in the Ceph
Leadership Team meetings.

We're happy to announce the 5th backport release in the Pacific series.
We recommend users to update to this release. For a detailed release
notes with links & changelog please refer to the official blog entry at
https://ceph.io/en/news/blog/2021/v16-2-5-pacific-released
Notable Changes
---------------
* `ceph-mgr-modules-core` debian package does not recommend
`ceph-mgr-rook` anymore. As the latter depends on `python3-numpy` which
cannot be imported in different Python sub-interpreters multi-times if
the version of `python3-numpy` is older than 1.19. Since `apt-get`
installs the `Recommends` packages by default, `ceph-mgr-rook` was
always installed along with `ceph-mgr` debian package as an indirect
dependency. If your workflow depends on this behavior, you might want to
install `ceph-mgr-rook` separately.
* mgr/nfs: `nfs` module is moved out of volumes plugin. Prior using the
`ceph nfs` commands, `nfs` mgr module must be enabled.
* volumes/nfs: The `cephfs` cluster type has been removed from the `nfs
cluster create` subcommand. Clusters deployed by cephadm can support an
NFS export of both `rgw` and `cephfs` from a single NFS cluster instance.
* The `nfs cluster update` command has been removed. You can modify the
placement of an existing NFS service (and/or its associated ingress
service) using `orch ls --export` and `orch apply -i ...`.
* The `orch apply nfs` command no longer requires a pool or namespace
argument. We strongly encourage users to use the defaults so that the
`nfs cluster ls` and related commands will work properly.
* The `nfs cluster delete` and `nfs export delete` commands are
deprecated and will be removed in a future release. Please use `nfs
cluster rm` and `nfs export rm` instead.
* A long-standing bug that prevented 32-bit and 64-bit client/server
interoperability under msgr v2 has been fixed. In particular, mixing
armv7l (armhf) and x86_64 or aarch64 servers in the same cluster now works.
