Thanks Wido. That seems to have worked. I just had to pass the keyring and monmap when calling mkfs. I saved the keyring from the monitors data directory and used that, then I obtained the monmap using ceph mon getmap -o /var/tmp/monmap. After starting the monitor it synchronized and recreated the leveldb. _______________________________________________ ceph-users mailing list ceph-users@xxxxxxxxxxxxxx http://lists.ceph.com/listinfo.cgi/ceph-users-ceph.com
