Comment 1 for bug 1892294

This may be a duplicate of https://bugs.launchpad.net/juju/+bug/1890828. I need more data to confirm please.

Can you confirm if the unit upgraded before or after the relation failures? It will be in the unit's log. I look for "running jujud".

The best recovery might be to remove the gnocchi/2 unit and add a new unit to replace it.

The errors from mysql/2 look to be a duplicate of: https://bugs.launchpad.net/juju/+bug/1891234
