So, for some reasons this is not needed anymore, but I don't think this
may create problems, surely the RA maintainer has done all the necessary
tests.

Here it is, note that I'm using DRBD instead of a shared storage
(basically each drbd is a stand alone export that can reside
independently on a node):

Note that I've grouped all the nfs-server daemons (portmap, nfs-common
and nfs-kernel-server) in the cloned group nfs_clone.
