Mounting

[Zenon Panoussis <oracle@provocation.net>]

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.
