Hi Adam, Thank you for the details. I see that the cephadm on the Ceph cluster is different from the host that is being added. I will go thru the ticket and the logs. Also the cluster is on Ubuntu Focal and the new host is on Ubuntu Jammy The utility: cephadm 16.2.13-1focal amd64 cephadm utility to bootstrap ceph daemons with systemd and containers cephadm 17.2.5-0ubuntu0.22.04.3 amd64 cephadm utility to bootstrap ceph daemons with systemd and containers Thanks again, Anantha From: Adam King <adking@xxxxxxxxxx> Sent: Tuesday, June 20, 2023 4:25 PM To: Adiga, Anantha <anantha.adiga@xxxxxxxxx> Cc: ceph-users@xxxxxxx Subject: Re: Error while adding host : Error EINVAL: Traceback (most recent call last): File /usr/share/ceph/mgr/mgr_module.py, line 1756, in _handle_command There was a cephadm bug that wasn't fixed by the time 17.2.6 came out (I'm assuming that's the version being used here, although it may have been present in some slightly earlier quincy versions) that caused this misleading error to be printed out when adding a host failed. There's a tracker for it here https://tracker.ceph.com/issues/59081 that has roughly the same traceback. The real issue is likely a connectivity or permission issue from the active mgr trying to ssh to the host. In the case I saw from the tracker, it was caused by the ssh pub key not being set up on the host. If you check the cephadm cluster logs ("ceph log last 50 debug cephadm") after trying to add the host I'm guessing you'll see some error like the second set of output in the tracker that will hopefully give some more info on why adding the host failed.
