View Full Version : [ubuntu] some confusion regarding mounting nfs partitions for a cluster

May 5th, 2008, 03:00 AM
I am trying to build a beowulf cluster, generally following the configuration this guy came up with here: http://www.calvin.edu/~adams/research/microwulf/sys/microwulf_notes.pdf

My chief difficulty stems from where I must edit fstab. My partitions are roughly as follows:

22gig /root
22gig /home
2gig swap
8gig /root for node1
8gig /root for node2

There is an ubuntu server install on each of the 2 nodes. The instructions read

"Before you can export the diskless nodes root partitions over NFS, you must
mount them somewhere on the head node. I mounted them to /nodes/nfs/node1,
/nodes/nfs/node2 and /nodes/nfs/node3. Feel free to change this, but those
are the locations I will reference for the rest of this howto. Put appropriate
entries in /etc/fstab so these are mounted automatically at boot."

which doesn't help too much if one is new to this. I have added
/dev/sda6 /nodes/nfs/node1 ext3 defaults 0 2
/dev/sda7 /nodes/nfs/node2 ext3 defaults 0 2 to my fstab file.

My question is this: How can I tell this actually worked? Will I see these partitions under computer? Do I have to create a folder called /nodes/nfs ?

I know this topic is not exactly common but surely someone knows. If not, is there another forum I could be pointed to?

I've started a new discussion, to try and bring together threads in different forums about Ubuntu clustering at:
