Listing 1. Typical LVM Disk Configuration

[root@recoverybox ~]# /sbin/sfdisk -l /dev/hda

Disk /dev/hda: 39560 cylinders, 16 heads, 63 sectors/track
Warning: The partition table looks like it was made
  for C/H/S=*/255/63 (instead of 39560/16/63).
For this listing I'll assume that geometry.
Units = cylinders of 8225280 bytes, blocks of 1024 bytes, counting from 0
