    LVM2/device-mapper diagnostics
    ==============================

    If you use the 'lvs' reporting tool, we'll get fuller information more
    concisely, so we can check for any anomalies.
    [Unlikely to be any based on what you've posted so far, but worth
    eliminating the possibility.]

    Run:
    vgs -v
    lvs -v
    pvs -v

    Can you confirm that you're not running *any* LVM or device-mapper
    commands during your backup sequence?

    Confirm the versions by running:
    lvm version
    dmsetup targets

    And dump the static device-mapper state, by running:
    dmsetup -v table
    dmsetup status

    [I'll get that fixed to provide a column-based output too.]

    And finally mount sysfs and run
    ls -ld .../block/dm-*

    [This lot ought to get scripted.]
