Known issues

Potential known upgrade bugs and non-standard procedures are listed in the OpenStack Charm Guide:

• Issues, charm procedures, and OpenStack upgrade notes

Manila Ganesha

Certain versions of the manila-ganesha charm incorrectly report their workload version, which can lead to false positive COU errors resembling the following one:

[WARNING] Not possible to find the charm manila-ganesha in the lookup
[ERROR] 'manila-ganesha' with workload version 17.1.0 has no compatible OpenStack release.

See bug 2060751 for details.

If affected, refresh the manila-ganesha charm to its most recent version (within the same release channel) and re-run COU.

Rabbitmq Server

The rabbitmq-server charm must have enable-auto-restarts=False for COU to work properly due to the known charm bug.

See bug 2046381 for details.

We suggest that users should temporarily set enable-auto-restarts=False when performing cou upgrade, and rollback to original setting after the upgrade is completed.

Ceph not updating version

Ceph applications might need manual intervention after the upgrade because the payload version doesn’t update automatically. You might find a message like this

[WARNING] Ceph mon (ceph-mon/0) sees mismatched versions in ceph daemons:
{
    "mon": {
        "ceph version 18.2.4 (e7ad5345525c7aa95470c26863873b581076945d) reef (stable)": 3
