I think there is some confusion on the `orch` cli commands.

`orch ps` will list the cephadm daemons, whereas `orch ls` should be used to list the cephadm services.

In this case `mds.ceph-packaging.mira093.xgafwr` is a daemon name where the `orch rm` command wants a service name.

To remove a service (and all daemons associated with the service):

$ ceph orch rm mds.ceph-packaging

To only remove a single daemon, you'd need to set the service to `unmanaged`:

$ ceph orch apply mds ceph-packaging --unmanaged
$ ceph orch daemon rm mds.ceph-packaging.mira093.xgafwr

Thanks for the explanation. It seems cephadm eventually cleaned them up in any case.

I'll convert this to a Documentation ticket.
