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.
