[Gluster-users] Expanding a Volume with GlusterSP

This helps a lot... if we move off of GlusterSP and use GlusterFS (which it 
looks like we might have to do since SP doesn't give you root access) then I 
can attempt this method. Any advice for how to re-balance the volume once 
this is done? Is there a command I need to call?
