Data is large and cannot be copied to the local drives od the compute nodes as the data is large.
I understand that. I think that you have storage attached to your cluster head node - the 'SAN storage' you refer to. Lets' call that volume /data All you need to do is edit the /etc/exports file on the cluster head node, and include the name of that storage area. Just cut and paste one of the other lines inthe file, which will have a definition of the IP Address range of the cluster nodes and the mount parameters. On all the cluster nodes, you will need to run a command 'mkdir /data/ The create a new /etc/fstab file with an additional line which contains /data and the name of the cluster head node You will then have to update the node image with this new /etc/fstab, or push the /etc/fstab out to all compute nodes finally run the command 'mount /data/ on all compute nodes.
