[Bug 2139385] Re: Update Ceph to new 20.2.0 (Tentacle) version

[Skia]

The Ceph 20.2.0 release has been out since November. Please try to make that kind of update earlier in the cycle next time, to accommodate for more testing time on the many reverse depends.
In that particular case, considering what's described in the [Regression potential] section, is there a real need to have this particular release in Resolute, or could this in principle wait for next cycle?

To clarify, I'm not strictly against granting that FFe, but I'd need a
rational as to why this is needed, as well as a better described Test
Plan taking into account the Ubuntu archive, not the Ceph charms.

Also, unrelated to the outcome of that FFe, this bug description is
quite confusing. It's using the SRU template while not being an SRU.
It's also mentioning charm testing quite a lot, but this is about a
debian package in the Ubuntu archive. And finally, as mentioned above,
the description is kinda missing the **why** this update is needed.

Title:
   Update Ceph to new 20.2.0 (Tentacle) version

Status in ceph package in Ubuntu:
  In Progress

Bug description:
  [Impact]

  The update contains the following package updates:
  https://ceph.io/en/news/blog/2025/v20-2-0-tentacle-released/

  Key differences from upstream:
  - UADK is not used in ARM64 as it requires checking out a repository during
    build time.

  [Test Case]

  This SRU will run all functional tests with the packages in 'proposed'
  for every Ceph charm maintained by Canonical's Ceph team, so that
  there's a higher chance of catching bugs associated with any Ceph
  component.

  The charms for which the functional tests will be run are: ceph-mon, ceph-osd,
  ceph-radosgw, ceph-proxy, ceph-nfs, ceph-nvme, ceph-fs and ceph-rbd-mirror.

  [Regression Potential]

  Ceph is a critical package as it underpins large scale data storage
  and integrity checking, and care must be taken to not introduce any
  data loss regressions. ceph also is a common backing store for
  OpenStack virtual machines through ceph-rbd, and care must be taken to
  not break any API or ABI compatibility with current OpenStack
  releases.

  In order to mitigate the regression potential, the results of the
  aforementioned tests will be attached to this bug.
