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.
Yeah, I think so. The OSD should try to block the further possibly
corrupting writes to it.
The blocklist items will be in format likes {IP:Port:Nonce} of the last
crashed MDS, not the clients. And after the new MDS starting, it will
get a new nonce, so you won't see the new MDS will be denied to access.
Thanks

Thanks for your reply and best regards,

Subject: Re: MDS host in OSD blacklist
Hi Frank,
This should be the same issue with
https://tracker.ceph.com/issues/49132, which has been fixed.
Thanks

Hi all,
we have an octopus v15.2.17 cluster and observe that one of our MDS hosts showed up in the OSD blacklist:
# ceph osd blacklist ls
192.168.32.87:6801/3841823949 2023-03-22T10:08:02.589698+0100
192.168.32.87:6800/3841823949 2023-03-22T10:08:02.589698+0100
I see an MDS restart that might be related; see log snippets below. There are no clients running on this host, only OSDs and one MDS. What could be the reason for the blacklist entries?
Thanks!
