=== Extend the LVM LV ===

To keep things simple, we'll just use some of the free space we left on our <span class="code">/dev/drbd0</span> LVM physical volume. If you need to add more storage to your LVM first, please follow the instructions in the article: "[[Adding Space to an LVM]]" before proceeding.

Let's add <span class="code">50GB</span> to our GFS2 logical volume <span class="code">/dev/drbd_vg0/iso_store</span> from the <span class="code">/dev/drbd0</span> physical volume, which we know is available because we left more than that back when we first setup our LVM. To actually add the space, we need to use the <span class="code">lvextend</span> command:

<source lang="bash">
lvextend -L +50G /dev/drbd_vg0/iso_store /dev/drbd0
</source>

Which should return:

<source lang="text">
  Extending logical volume iso_store to 70.00 GB
  Logical volume iso_store successfully resized
</source>

If we run <span class="code">lvdisplay /dev/drbd_vg0/iso_store</span> now, we should see the extra space.
