LVM - Create a logical volume using LVM

Logical volumes are created using the lvcreate command: 

lvcreate --size 256M --name foo /dev/vg01

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: 

lvdisplay /dev/vg01/foo

This should give a response of the form: 

--- Logical volume ---
LV Name                /dev/vg01/foo
VG Name                vg0
