M3: Moving NFS server

Running V2.0.0 in small (21) node cluster with most nodes RedHat. NFS has been working fine, but I need to migrate it to a better system before upgrading to V2.1.0. Here is what I did:

 - Stopped clients using NFS mount; unmounted.
 - Stopped NFS server on node (HD5)
 - Stopped mapr-warden on new NFS server (HD10); Installed mapr-nfs package; updated roles file; re-ran configure.sh; re-started mapr-warden.
 - Logs look fine (I think); Web UI shows NFS server running on new node (HD10). No alarms on HD10.
 - Attempted mount from remote client with: sudo mount hd10:/mapr /mapr
 - Response: mount.nfs: No route to host. (Same response with fully qualified name for HD10). Can ping with either address.

From the page http://www.mapr.com/doc/display/MapR/Setting+Up+MapR+NFS it says "The portmapper service must be running. You can use the ps a | grep portmap command to check." but I see no such thing running. How to start it?

Do I have to change anything license wise to switch hosts?

Thanks,
Terry
