Thanks, Peasant,
I guess that will be the simplest solution to this problem. Was trying to make sure this could be done automatically. But guess have to do manual mounts when we face issues.

With the current setup. There is a problem with the backups not initiating from node2. Even when both nodes are running only node1 can start the backups. Not sure what is wrong. My fstab entries for both nodes for reference.

Node1: /dev/mapper/mpath7 /backup ext3 defaults 1 2
Node2: 172.16.184.220:/backup /backup nfs defaults 1 2

The IP above is for node1.

orte-clean(1)							     Open MPI							     orte-clean(1)

NAME
orte-clean - Cleans up any stale processes and files leftover from Open MPI jobs. SYNOPSIS
orte-clean [--verbose] mpirun --pernode [--host | --hostfile file] orte-clean [--verbose] OPTIONS
[-v | --verbose] This argument will run the command in verbose mode and print out the universes that are getting cleaned up as well as pro- cesses that are being killed. DESCRIPTION
orte-clean attempts to clean up any processes and files left over from Open MPI jobs that were run in the past as well as any currently running jobs. This includes OMPI infrastructure and helper commands, any processes that were spawned as part of the job, and any temporary files. orte-clean will only act upon processes and files that belong to the user running the orte-clean command. If run as root, it will kill off processes belonging to any users. When run from the command line, orte-clean will attempt to clean up the local node it is run from. When launched via mpirun, it will clean up the nodes selected by mpirun. EXAMPLES
Example 1: Clean up local node only. example% orte-clean Example 2: To clean up on a specific set of nodes specified on command line, it is recommended to use the pernode option. This will run one orte-clean for each node. example% mpirun --pernode --host node1,node2,node3 orte-clean To clean up on a specific set of nodes from a file. example% mpirun --pernode --hostfile nodes_file orte-clean Example 3: Within a resource managed environment like N1GE, SLURM, or Torque. The following example is from N1GE. First, we see that we have two nodes with two CPUs each. example% qsh -pe orte 4 example% mpirun -np 4 hostname node1 node1 node2 node2 Clean up all the nodes in the cluster. example% mpirun --pernode orte-clean Clean up a subset of the nodes in the cluster. example% mpirun --pernode --host node1 orte-clean SEE ALSO
