In principle not neccessary any more with linux-2.6.x, you need to have mounted /proc/fs/nfsd. The only trouble you still have are these rpc.statd / lockd information in /var/lib/nfs/sm, I think these still should be equal on both servers, but locking information are not part of the NFS protocol (e.g. RFC 1813) up to v3.
