I'm facing yet another one of "those problems", more likely caused by lack of knowledge and/or documentation than by anything else. # mount.ceph 192.168.178.100:6789:/ /vol mount error 22 = Invalid argument # dmesg -c libceph: no secret set (for auth_x protocol) libceph: error -22 on auth protocol 2 init It looks very much like http://marc.info/?l=ceph-devel&m=130072087704874&w=2 . Yes, I have enabled cephx, but I have no clue how to tell the client what key to use. I tried # cauthtool -l /etc/ceph/admin.keyring # mount.ceph 192.168.178.100:6789:/ /vol -v -o name=<auid>,secret=<key> but all I got was ceph: Unknown mount option name ceph: Unknown mount option secret mount error 1 = Operation not permitted Yet, 'man mount.ceph' says name string, used with authx, Default: guest secret string, used with authx Commenting out "auth supported = cephx" gets rid of the problem and lets the store be mounted, but it's a workaround, not a solution. Any ideas? This is ceph-0.26 with vanilla kernel 2.6.38.2.
