Hi Greg, Thanks for the reply. After looking more closely at /etc/ceph/rbdmap I discovered it was corrupted. That was the only problem. I think the dmesg line 'rbd: no image name provided' is also a clue to this! Hope that helps any other newbies! :) Thanks again, Chad. _______________________________________________ ceph-users mailing list ceph-users@xxxxxxxxxxxxxx http://lists.ceph.com/listinfo.cgi/ceph-users-ceph.com
