Dear Xiubo, thanks for that link. It seems like its a harmless issue. I believe I have seen a blocked OP in the ceph warnings for this MDS and was quite happy it restarted by itself. Looks like its a very rare race condition and does not lead to data loss or corruption.
In a situation like this, is it normal that the MDS host is blacklisted? The MDS reconnected just fine. Is it the MDS client ID of the crashed MDS that is blocked? I can't see anything that is denied access. Thanks for your reply and best regards, ================= Frank Schilder AIT Risø Campus Bygning 109, rum S14 ________________________________________ From: Xiubo Li <[email protected]> Sent: 22 March 2023 07:27:08 To: Frank Schilder; [email protected] Subject: Re: [ceph-users] MDS host in OSD blacklist Hi Frank, This should be the same issue with https://tracker.ceph.com/issues/49132, which has been fixed.
