Bug Description
Hey there.
We upgraded from rocky to stein and facing a strange error. Our cinder-ceph volume services gets marked as down after a few seconds. So we looked into this and found a error in the logs:

It looks like, because of this error the service gets marked down. This issue is definitly linked to this: https:/
If we put a try-catch block around this block, the services stays up, but i am not sure if something else will break.
This is in our perspective a high priority bug, because we are not able to use one of our ceph backends.
