.Users are no longer able to remove the Ceph Manager service using `cephadm`
Previously, if a user ran a `ceph orch rm mgr` command, it would cause `cephadm` to remove all the Ceph Manager daemons in the storage cluster, making the storage cluster inaccessible.
With this release, attempting to remove the Ceph Manager, a Ceph Monitor, or a Ceph OSD service using the `ceph orch rm _SERVICE_NAME_` command displays a warning message stating that it is not safe to remove these services, and results in no actions taken.

moving this to 5.0z1 We can recover the cluster by following the steps - The issue is seen only for MON and MGR now. Cluster will be in accessible state for other services like OSDs, RGW etc but all daemons of that services will be down. Hence, we need warning msgs for all type of services when we use ceph orch stop <service name> option How to recover, Go to /var/lib/ceph/fsid and note the mon service And perform systemctl start ceph-<fsid>@monservicename - what we have in /var/lib/ceph/mon service → repeat this for all mon/mgr nodes Check ps -ef | grep ceph-mon/ceph-mgr ---> verify the process id created for ceph-mon/ceph-mgr Ex: systemctl start ceph-f64f341c-655d-11eb-8778-fa163e914bcc Hi Mike, Can you review from a support perspective if the recovery procedure is good to differ this BZ to 5.0z1?
