Your diagram does not match the storage defined here.  I believe you
took this from the example I provided last week.  My setup has a
separate raid unit that is accessible by both servers.  Your setup has
hard drives in each server.  This is a completely different setup.  I
think you can do what you want using either NFS or GNBD, but I can't
help you there as I have never attempted a cluster setup using either
of those.

To give you an idea, my setup looks like this:

           Load Balancer
           /           \
       Server1      Server2
           \           / 
        Raid Storage with GFS
