Please keep in mind, not just LVM, but LVM's "thin volumes"

If you use LVM, it is quite simple just to increase the volume. When you 
add new HDDs, create new logical volumes on them, make the file system, 
and add it as another brick to your gluster volume (gluster add-brick 
volumename replica N ip.add.re.ss:/new-brick ... etc...).
