Try rebooting the head node, waiting until it is completely booted, and then
rebooting all the client nodes. If everything is set up right, that might
fix the problem. You can check if it is working by sshing to the compute
node and doing "ls /home" and comparing it to the head node.
Check /etc/exports and make sure /home is exported to the internal network,
and the fstab in the image and nodes to make sure it is being mounted.
Another common problem is an incorrect /etc/hosts files, see if it is
something like
127.0.0.1 localhost.localdomain localhost
10.0.0.1 oscarmaster.oscardomain oscarmaster nfs_oscar pbs_oscar
If the cluster hostname is on the same line as localhost, that will cause
this kind of problem because the nodes will be trying to contact themselves
instead of the head node for nfs mounts.
Not much will work without nfs working unfortunately.
