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,
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.
