[Gluster-devel] NFS reexport

[Amar S. Tumballi]

some correction to spec file  (definition of 'ns' volume was missing in
earlier mail).

NOTE : In this case, unify can be used on the client side too, (using 3
protocol/client with "option remote-subvolume usb1", "option
remote-subvolume usb2", and "option sub-volume nfs") but server side
unification will work out better as it will be quite faster as unify has
posix directly under it.
