[Bug 2151199] Re: [SRU] ceph 20.2.1

[Luciano Lo Giudice]

This new release is currently blocked due to a very serious bug
affecting the Rados Gateway package:
https://bugs.launchpad.net/ubuntu/+source/ceph/+bug/2154304

There's no fix upstream, so the Ceph team is trying to resolve it by
itself.

Title:
  [SRU] ceph 20.2.1

Status in ceph package in Ubuntu:
  New

Bug description:
  [Impact]
  This release fixes several bugs. We would like to make sure all of our users have access to these improvements.

  The update contains the following package updates:
     * ceph 20.2.1 https://docs.ceph.com/en/latest/releases/tentacle/#v20-2-1-tentacle

  Notable changes:
      * This fixes a severe upgrade bug that prevented the OSD daemons from coming up when using fast EC pools.

  Key differences from upstream:
      * The following PR has been backported from upstream, as otherwise the cephadm component is unusable: https://github.com/ceph/ceph/pull/66244

  [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.

  The functional test suite includes upgrade testing from the current
  stable release to the proposed (in this case, from 20.2.0 to 20.2.1)

  [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.
