Error mounting snapshot partition


Hi All,

When running mylvmbackup I got the following error:

20081215 16:05:29 Info: Running: /bin/mount -o ro
/dev/slash/produce_snapshot /var/tmp/mylvmbackup/mnt/backup
mount: you must specify the filesystem type
20081215 16:05:29 Error: FAILED: mount snapshot (exit status 32)

It was necessary for me to edit mylvmbackup as I didn't seem to see any
option to specify via command line any option to solve it.

   return run_command("mount snapshot", $command);

This produced an intended result, but I 'm surprised this hasn't been picked
up before.  Is there an alternative way (I'm assuming I could add to fstab
with nomount on load, but have yet to test that).
