====== Ubuntu - LVM - Create a logical volume using LVM ======

Logical volumes are created using the **lvcreate** command:

<code bash>
lvcreate --size 256M --name foo /dev/vg01
</code>

The volume will be accessible as either **/dev/vg01/foo** or **/dev/mapper/vg01-foo**.  It may be used in much the same way as a hard drive partition.

----

===== Testing =====

Verify the existence of the logical volume using the **lvdisplay** command:

<code bash>
lvdisplay /dev/vg01/foo
</code>

This should give a response of the form:

<code>
--- Logical volume ---
LV Name                /dev/vg01/foo
VG Name                vg0
LV UUID                afaHxF-nZrA-S1eo-kjsY-mt6C-p04e-IU8Bqu
LV Write Access        read/write
LV Status              available
# open                 0
LV Size                256.00 MB
Current LE             64
Segments               1
Allocation             inherit
Read ahead sectors     auto
- currently set to     256
Block device           254:64
</code>

===== Next steps =====

Having created a new logical volume you may want to:

  * Create a filesystem on it
  * Use it as a swap device
