Quick Usage

Mounting / Unmounting Volumes

If you have a LVM partition, you can see what physical volumes there are under the LVM by running:

# pvs
PV               VG                Fmt    Attr    PSize       PFree
/dev/hda2        VolGroup01        lvm2   a-      148.94G     32.00M

The volume group (VG) is VolumeGroup01. To view the logical volumes under this volume group, run:

# lvdisplay /dev/VolumeGroup01

Once you have located the logical volume you want to mount, say LogVol00, run:

# mount /dev/VolumeGroup01/LogVol00 /mnt/disk
