[Bug 2065515] Re: [SRU] Ceph Squid release candidate

[Jay Ring]

Today I ran an update on the current version Ubuntu 24.04.1 LTS.

My monitors now crash with the same error reported above by Neils.

Is there any way to fix this problem?

Bug description:
  [Impact]
  Ubuntu 24.04 LTS users are currently using a development snapshot of Ceph; the upstream project are working towards a release and produced a 19.1.0 RC which we should include in 24.04 as a stepping stone towards release.  There are current know upgrade issues with the development snapshot included.

  [Test Case]
  No reproducer for this bug; RC will be tested in the following ways:

  - As part of a core24 based microceph built from proposed
  - Using the standard OpenStack Regression Testing utilised for validation of OpenStack and Ceph updates under the MRE already in place:

  https://wiki.ubuntu.com/OpenStack/StableReleaseUpdates

  Test results will all be attached to this bug report.

  [Where things might go wrong]
  As this is an RC there will likely be outstanding bugs that will need to be resolved by the upstream project before release; This is expected but the RC will be an improvement on the current development snapshot in terms of quality.
