    I'm using the same backup script that I was using before without LVM,
    there are no snapshots or anything. It's just Amanda with a simple
    script to run it.

    > Confirm the versions by running:

    # lvm version
      LVM version: 2.00.06 (2003-08-20)

      Driver version: 4.1.0

    The dmsetup I have installed doesn't have this command.
