I am using OSCAR 5.0 on Fedora 5.0 x86_64. My head node uses SCSI drives,
which are expensive to add more space. In order to add more disk space, I
added a client node which uses SATA. I just added 7 400GB drives to that
node. If I am right, I need to let all the other nodes in the cluster be
able to access these SATA drives. Do I need to start NSF daemon on this
client node and then mount all the partitions on all the other nodes? That
will probably affect performance of the cluster if I choose to do that.
Actually, I tried to start NFS service on the client node and got some error
message like "unable to find recovery directory . starting 90 seconds grace
period."
I searched mailing-lists archives and could not find an answer. The OS on
each client takes only a few GB. Suppose you have a big drive, then how can
people use the rest of the space from any node in the cluster? It seems to
me that you need to start NFS daemon on every node in order to do that.
Many thanks,
Jinsong Ouyang
