dmsetup table says the following: $ dmsetup table VolGroup00-LogVol01: 0 3145728 linear 3:2 152830336 VolGroup00-LogVol00: 0 152829952 linear 3:2 384 where device [3:2] is /dev/hda2 (the root partition) $ ls -l /dev/hda2 brw-rw---- 1 root disk 3, 2 Jul 25 22:48 /dev/hda2 And fdisk says: $ fdisk -u -l /dev/hda Disk /dev/hda: 80.0 GB, 80026361856 bytes 255 heads, 63 sectors/track, 9729 cylinders, total 156301488 sectors Units = sectors of 1 * 512 = 512 bytes Device Boot Start End Blocks Id System /dev/hda1 * 63 208844 104391 83 Linux /dev/hda2 208845 156296384 78043770 8e Linux LVM We've mounted VolGroup00-LogVol00 on '/', and its dmsetup table makes some sense, in that there are 156087540 sectors in /dev/hda2, which is large enough to hold both VolGroup00-LogVol00 and VolGroup00-LogVol01, but I'm wondering where VolGroup00-LogVol01 might've crept in during the install? It has 3145728 sectors, and starts after VolGroup00-LogVol00 ends, but it isn't mounted and otherwise seems unecessary. Is this typical of a default FC4 install, specifing that '/' be a managed volume, did we somehow hit the wrong buttons?
