Hi Robert,

You'd need to adjust the lnet options line in /etc/modprobe.conf to force
Lustre to bind to all your NICs, I believe it binds to the first one
available unless instructed otherwise.

Try this:

-- cut --
options lnet networks="tcp0(eth1),tcp1(eth2),tcp3(eth3)"
-- cut --

which will serve up the Lustre volume on each of your interfaces via three
different LNET networks. You may be able to organize them all under a single
LNET network, but without the right routing in place, it gets very
complicated.

hth,
Klaus
