*
* Pull out name & uuid, device, device extent start #, segment size, extent size.
*
* NB can be multiple rows per volume if they have many extents
*
* NB lvs from some distros (e.g. SLES10 SP2) outputs trailing ":" on each line
* NB lvs from some distros (e.g. SLES10 SP2) outputs trailing "," on each line
*
* NB Encrypted logical volumes can print ':' in their name, so it is
* not a suitable separator (rhbz 470693).
