Following this tutorial assumes that you have followed along with the other two parts in this series. However, if you already have some familiarity with Linux you should be able to follow along.
Add a disk to the volume group
One of the great things about lvm is that you can add and remove physical volumes on the fly without data loss and without interrupting services.
