Dear all,
I have a two hosts setup, and I recently rebooted a mgr machine without
"set noout" and "set norebalance" commands.
The "darkside2" machine is the cephadm machine, and "darkside3" is the
improperly rebooted mgr.
Now the darkside3 machine does not resume ceph configuration:
[root@darkside2 ~]# ceph orch host ls
HOST ADDR LABELS STATUS
darkside2 darkside2
darkside3 172.22.132.189 Offline
If I understood the docs correctly, I should
[root@darkside2 ~]# ceph orch host add darkside3
But this fails because darkside3 doesn't accept root ssh connnections.
I presume this has been discussed before, but I couldn't find the
correct thread. Could someone please point me in the right direction?
Cordially,
Renata.

Hi all!
I want to register in this thread the debug and solution of this
problem, for future reference.
Thanks to Murilo Morais who did all the debugging!
The issue happened because when the machine rebooted, it applied a new
sshd configuration that prevented root ssh connections. Specifically, I
had added an "AllowGroups" line on /etc/ssh/sshd_config to prevent my
users from ssh'ing into this machine.
For root to continue to be allowed to ssh login with this parameter, I
added the "root" group in the "AllowGroups" variable. Perhaps there
better solutions, but this works.
After fixing this, I restarted ceph.target on the problematic host and
did "ceph orch host add darkside3" on the main mgr. Now everything works.
Cordially,
Renata.
