Greetings,

I have two Beowulf clusters on two subnets hanging off different 
machines.  (Actually, one has six different subnets to make it a flat 
network topology on more machines than will fit on a single switch, but 
that's not important.)  One head node (call it "head1") is my NIS/NFS 
server, so that cluster's config was easy.  The other head node 
("head2") is an NIS/NFS client.

I've set up an NIS slave on head2, which doesn't quite work (but I think 
I know why and haven't exhausted all of the possible things to do).

But is there such a thing as an NFS slave?  I try to export /home from 
head2, which mounts it from head1, but when clients mount it from head2, 
/var/log/messages shows:

Jul  3 13:22:25 head2 rpc.mountd: authenticated mount request from 
node10.longevity.edu:736 for /home (/home)
Jul  3 13:22:25 head2 rpc.mountd: getfh failed: Operation not permitted

I guess this is because it's not a local disk.  Is this possible to do?

The second head node is running 2.4.18 with the 2.4.18-athlon .deb's 
config plus SMP and nfs-kernel-server, both from woody.
