Sysadmins should use the 'multipath' tool to decode it. What I would like however, is an additional dmsetup command line option that would decode each of the table lines into a human-readable format. Something like: dmsetup table --expanded [Details: libdevmapper will acquire a per-target-type built-in plug-in, one function of which will be to do this decoding.] > You should show how to create a snapshot device using device-mapper.
