Right now, my cluster is one node, with additional 50 to be brought
on-line once I resolve the automount problem. The job I am running is
very simple, no nfs load on server.
my $usecp I believe is correct and works properly after the nfs dir is
$usecp *:/fs/userB1 /fs/userB1
My auto.home file:
userB1 -rw,hard,intr userB:/userB/u1
I believe it is an automount issue and I need to tweak a parameter in a
config file. Not sure which one it is at this point.
