Mounting a Linux LVM volume

You do not mount a partition of type "Linux LVM" the same way you mount a partition using a standard Linux file system (e.g. ext2, ext3).

$ fdisk -l /dev/hda

Disk /dev/hda: 160.0 GB, 160041885696 bytes 255 heads, 63 sectors/track, 19457 cylinders Units = cylinders of 16065 * 512 = 8225280 bytes

 Device Boot      Start         End      Blocks   Id  System

/dev/hda1 * 1 13 104391 83 Linux /dev/hda2 14 19457 156183930 8e Linux LVM

mount /dev/hda2 /tmp/mnt

mount: /dev/hda2 already mounted or /tmp/mnt busy

First, let's determine the volume group containing the physical volume /dev/hda2.

$ pvs

PV         VG         Fmt  Attr PSize   PFree 
/dev/hda2  VolGroup01 lvm2 a-   148.94G 32.00M
/dev/hdb2  VolGroup00 lvm2 a-   114.94G 96.00M

Next, let's list the logical volumes in VolGroup01.

$ lvdisplay /dev/VolGroup01

1. – Logical volume —

LV Name /dev/VolGroup01/LogVol00

VG Name                VolGroup01
LV UUID                zOQogm-G8I7-a4WC-T7KI-AhWe-Ex3Y-JVzFcR
LV Write Access        read/write
LV Status              available
# open                 0
LV Size                146.97 GB
Current LE             4703
Segments               1
Allocation             inherit
Read ahead sectors     0
Block device           253:2
 
--- Logical volume ---
LV Name                /dev/VolGroup01/LogVol01
VG Name                VolGroup01
LV UUID                araUBI-4eer-uh5L-Dvnr-3bI6-4gYg-APgYy2
LV Write Access        read/write
LV Status              available
# open                 0
LV Size                1.94 GB
Current LE             62
Segments               1
Allocation             inherit
Read ahead sectors     0
Block device           253:3

The logical volume I would like to "mount" (in purely the computing-related sense) is /dev/VolGroup01/LogVol00. The other logical volume is a swap partition.

$ mount /dev/VolGroup01/LogVol00 /tmp/mnt
