Cheers Reed, just saw this and checked on my own. Also had one mon that ran on leveldb. I just removed the mon, pulled the new monmap and deployed it. After that all was fine. Thanks for paging the ML, so I've read it :D Boris # assuming there is only one mon and you are connected to the host that got the mon systemctl stop ceph-mon.target ceph mon rm `hostname -s` rm -rf /var/lib/ceph/mon/ceph-* ceph mon getmap -o /tmp/monmap sudo -u ceph ceph-mon --cluster ceph --mkfs -i `hostname -s` --monmap /tmp/monmap systemctl restart ceph-mon.target rm /tmp/monmap Am Mo., 3.
