Try something like:

	<resources>
		<ip address="138.102.22.33" monitor_link="1"/>
		<nfsexport name="/usr/local/genome"/>
		<nfsclient name="mig" options="ro,fsid=20"
			target="138.102.22.0/255.255.192.0"/>
		<nfsclient name="mig213" options="fsid=213,ro"
			target="138.102.22.213"/>
		<nfsclient name="mig217" options="ro,fsid=217" 
			target="138.102.22.217"/>
		<clusterfs name="my_cluster_fs" device="..." fstype="gfs"
			mountpoint="/usr/local/genome"/>
	</resources>

	<service autostart="1" domain="mig_fod" name="nfs" nfslock="1">
  		<ip ref="138.102.22.33"/>
		<clusterfs ref="/usr/local/genome">
			<nfsexport ref="/usr/local/genome"/>
				<nfsclient ref="mig"/>
			</nfsexport>
		</clusterfs>
	</service>
