This list is intended for Open MPI support, not general Linux cluster support. You might be able to get more detailed help from other forums and/or your local cluster support admin / vendor. Thanks! On Oct 3, 2012, at 6:58 AM, Syed Ahsan Ali wrote: > Thanks John for the detailed procedure. t

Thanks John for the detailed procedure. the fstab thing was in mind but it was not sure how to make it happen on compute nodes. I'll try this and let you know. Actually the cluster and SAN was deployed by a local vendor of Dell and they are not much sure about this thing. On Wed, Oct 3, 2012 at 3

If I may ask, which comapny installed thsi cluster for you? Surely they will advise on how to NFS mount the storage on the compute nodes?

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 o

Second option is good but the thing I don't understand is that when each and everything is NFS mounted to the compute nodes then why it can't takes the external SAN drives too, I don't know how to expo

You need to either copy the data to storage which the cluster nodes have mounted. Surely your cluster vendor included local storage? Or you can configure the cluster head node to export the SAN volume by NFS

Dear All I have a Dell Cluster running Platform Cluster Manager (PCM) , the compute nodes are NFS mounted with the master node. Storage (SAN) is mounted to the installer node only, the problem is that I am running a programme which uses data which resides on Storage , so as far as running the prog
