Load kernel module to support lvm2
modprobe dm-mod
Mount a partition (logical volume) on lvm managed disk (suppose the volume group is ubuntu, logical volume to be mounted is home)
Activate all known volume groups
vgchange -a y
Or specify the logical volume to be activated
lvchange -a y /dev/ubuntu/home
Display attributes of a logical volume
lvdisplay
Mount
mount /dev/ubuntu/home /media/home
Reference
man lvm
Run the following command^^
terry@tux:~$ man lvm | sed -n '/^COMMANDS/,/^OPTIONS/p' | grep .
COMMANDS

pvcreate — Initialize a disk or partition for use by LVM.
pvdisplay — Display attributes of a physical volume.
pvmove — Move physical extents.
pvremove — Remove a physical volume.
pvresize — Resize a disk or partition in use by LVM2.
pvs — Report information about physical volumes.
pvscan — Scan all disks for physical volumes.
vgcfgbackup — Backup volume group descriptor area.
vgcfgrestore — Restore volume group descriptor area.
vgchange — Change attributes of a volume group.
vgck — Check volume group metadata.
vgconvert — Convert volume group metadata format.
vgcreate — Create a volume group.
vgdisplay — Display attributes of volume groups.
vgexport — Make volume groups unknown to the system.
vgextend — Add physical volumes to a volume group.

vgimportclone — Import and rename duplicated volume group (e.g. a hard?
ware snapshot).
vgmerge — Merge two volume groups.
vgmknodes — Recreate volume group directory and logical volume special
files
vgreduce — Reduce a volume group by removing one or more physical vol?
umes.
vgremove — Remove a volume group.
vgrename — Rename a volume group.
vgs — Report information about volume groups.
vgscan — Scan all disks for volume groups and rebuild caches.
vgsplit — Split a volume group into two, moving any logical volumes
from one volume group to another by moving entire physical volumes.
lvchange — Change attributes of a logical volume.
lvconvert — Convert a logical volume from linear to mirror or snapshot.
lvcreate — Create a logical volume in an existing volume group.
lvdisplay — Display attributes of a logical volume.
lvextend — Extend the size of a logical volume.
lvmchange — Change attributes of the logical volume manager.
lvmdiskscan — Scan for all devices visible to LVM2.
lvmdump — Create lvm2 information dumps for diagnostic purposes.
lvreduce — Reduce the size of a logical volume.
lvremove — Remove a logical volume.
lvrename — Rename a logical volume.
lvresize — Resize a logical volume.
lvs — Report information about logical volumes.
lvscan — Scan (all disks) for logical volumes.
