[SOLVED] lvm snapshot -- where did I go wrong?

Hi. I've got an lv at /dev/mapper/vg0-root, 20GB containing an XFS filesystem. For the first time, I tried to create an lvm snapshot of it so I could make a backup image with partimage. Used this command:

# lvcreate -L 100M -n rootsnap -s /dev/vg0/root

Seemed to work okay. But partimage can't read it, and when I try to mount it myself I get:

# mount -t xfs /dev/vg0/rootsnap /mnt/test
mount: wrong fs type, bad option, bad superblock on /dev/mapper/vg0-rootsnap,
       missing codepage or helper program, or other error
       In some cases useful info is found in syslog - try
       dmesg | tail  or so

Did I mess up the lvcreate command or something?

google suggests you need nouuid (on the mount) for XFS.

did you check only..
mount /dev/vg0/rootsnap /mnt/test only ???

Thanks. That worked. I had never even heard of nouuid before.
