Hi,

I am facing an issue on Cephadm cluster setup. Whenever, I try to add remote devices as OSDs, command just hangs.

The steps I have followed :

sudo ceph orch daemon add osd node1:device

1. For the setup I have followed the steps mentioned in :
   https://ralph.blog.imixs.com/2020/04/14/ceph-octopus-running-on-debian-buster/

1. To make sure it is not facing ssh errors and  host is reachable I have tried the following commands:
   cephadm shell -- ceph config-key get mgr/cephadm/ssh_identity_key > key
   cephadm shell -- ceph cephadm get-ssh-config > config
   ssh -F config -i key root@hostname

              I am able to connect to the host as root.

1. Then I have tired collecting the log information
   
   1. Command : sudo cephadm logs --fsid e236062e-96ad-11ea-bedb-5254002e4127 --name osd
      Result :
      Traceback (most recent call last):
      File "/usr/sbin/cephadm", line 4282, in <module>
      r = args.func()
      File "/usr/sbin/cephadm", line 921, in _infer_fsid
      return func()
      File "/usr/sbin/cephadm", line 2689, in command_logs
      (daemon_type, daemon_id) = args.name.split('.', 1)
      ValueError: not enough values to unpack (expected 2, got 1)
   2. Commad : sudo ceph log last cephadm
       

Result :

But I am not able to infer from these log information. Can you please help me with the issue.
