Hi Eugen,
Thank you very much for your help!
In the end we found that running "sudo systemctl restart ceph.target" on
each Ceph node, one by one, monitoring the health of the Cluster with "ceph
status" on a separate terminal has been the solution. After restarting
everything all commands are now working fine, and the associated OpenStack
services and VMs also came back to life.
I hope this helps somebody else!
Best regards,
Sebastian
