That's how you identify with hard drive or partition belongs to what Volume Group. Somewhere in the Logical Volume info it will say: "LV Status available" To fix inconsistencies, check the filesystem e2fsck -fvy /dev/VolGroup00/LogVol00 To format (make sure to pick the correct one) mkfs.ext3 /dev/VolGroup00/LogVol00 mount as any other filesystem mount /dev/VolGroup00/LogVol00 /mnt/mountpoint Bottom line is you can use /dev/VolGroup00/LogVol00 as you would any hard drive device name such as /dev/hda1.
