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
— 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
