The available pacemaker resource agent script in /usr/libocf/resource.d/heartbeat/nfsserver has just a single parameter to point to the NFS init script. The resource agent calls the defined init script to perform much of the underlying work. The resource agent script does do sm-notify separately for the highly available IP address, but the RHEL6.4 nfslock script is still needed since it does more than just sm-notify.

for the sake of completeness: the above mentioned is for nfsv3, for nfsv4 you do not need nfslock.
