Hi Stefan, thanks for the hint. Yes, the mon store is owned by user ceph. It's a normal folder under /var/lib/ceph/mon/... and there are various files in there - all with owner ceph:ceph. Looks normal to me (like on the other nodes). I've read the docs you provided and I wonder which of those steps are actually necessary because I obviously have many of those things already in place. I guess the most important part is step 15, right? ceph-mon --mkfs -i stage2 --monmap /tmp/monmap --keyring /tmp/ceph.mon.keyring So I would completely delete the /var/lib/ceph/mon/ceph-stage2 folder and recreate it as empty, because the files in there have probably become corrupted, correct? Then I would run the above command and it would initialize a new monitor automatically in that folder by default? I don't have to specify the exact path on the command-line - it is automatically determined by the -i argument, right? So, I only need the keyring and the monmap. How do I get the monmap? I tried to run: ceph-mon -i stage2 --extract-monmap /tmp/monmap And I get some binary stuff written to /tmp/monmap. Is that a decent monmap? Is there also a way to extract the keyring? There's a keyring file in /var/lib/ceph/mon/ceph-stage2. Can I just use that one?
