= LVM =
LVM stands for Logical Volume Manager. It provides a way for extending filesystems by adding new partitions to the "logical volume".

== Creating the initial logical volume ==
 1. Create the partition(s) on the device

 {{{
# fdisk <device> }}}
 1. Create the Physical Volume entry
 {{{
# pvcreate <Partition Device>}}}
 1. Create the Volume Group
 {{{
# vgcreate <GroupName> <PhysicalVolume> }}}
 1. Verify the Volume Group was created. Take note of the "Total PE" field
 {{{
# vgdisplay }}}
 1. Create the Logical Volume
 {{{
# lvcreate --extents <Total PE> <VolumeGroup> }}}
 1. Verify the Logical Volume was created
 {{{
 # lvdisplay}}}
 1. Format the Logical Volume {{{
 # mke2fs /dev/<VolumeGroup>/<LogicalVolume> }}}

== Extending a filesystem running on LVM (untested and incomplete) ==
 1. Create partition of new device {{{
 # fdisk <device> }}}
 1. Create the new Physical Volume {{{
 # pvcreate <Partition> }}}
 1. Add the Physical Volume to the Volume Group {{{
 # vgextend ... }}}
 1. Extend the Logical Volume {{{
 # lvextend ... }}}
 1. Resize the filesystem {{{
 # ext2online/resize2fs ... }}}
