Hi Michael, It might be my fault not explaining too well. Here is a different description of the problem:
======================================================= The cluster has 3 nodes (n0 - master; n1 and n2 - slaves) and each has its own hard drive, named: /home, /home1 and /home2. We were able to mount /home to n1 and n2 so the cluster runs ok (we use MPI). The problem is that we could not access /home1 and /home2 from n0, when trying to use the hard drive for storage. Here is the situation: when in n0: read /home YES; read /home1 NO; read /home2 NO when in n1: read /home YES; read /home1 YES; read /home2 NO when in n2: read /home YES; read /home1 NO; read /home2 YES The 'mount: RPC: Program not registered' error msg pops out when we tried to mount /home1 or /home2 to n0. ======================================================= Hope this helps, Ivan >>> "Michael Edwards" <[EMAIL PROTECTED]> 10/10/06 4:31 PM >>> The mapping of home drives is from the master node to the compute nodes, so it sounds like your set up is working as I would expect it to. NFS takes care of returning changes made on the nodes back to the server automatically, you don't need to mount the home directories of the compute nodes back to the server, the data should simply stay in sync as long as the clocks are all synchronized. Perhaps I am not understanding your problem completely though.
