Hi,
I have two Infiniband clusters, each in a separate location with a
solid ethernet connectivity between each of them. Say they are named
cluster A and cluster B. All members of each clusters have both IB and
eth networks available to them, and the IB network is not routed between
cluster A and B, but ethernet is. On each clusters, I have 4 OSS's
serving FC disks. Clients on cluster A mounts Lustre disk from their
local cluster, and the same goes on for for cluster B, both on
Infiniband NIDs.
What I would like to achieve is client from cluster A to mount disks
from OSS's on cluster B on the ethernet connection. The same goes on
for clients in cluster B to mount disks from OSS's on cluster A.
From my readings in the luster 1.8.7 manual, I got:
7.1.1 Modprobe.conf
Options under modprobe.conf are used to specify the networks available
to a node.
You have the choice of two different options -- the networks option,
which explicitly
lists the networks available and the ip2nets option, which provides a
list-matching
lookup. Only one option can be used at any one time. The order of LNET
lines in
modprobe.conf is important when configuring multi-homed servers. *If a
server
node can be reached using more than one network, the first network
specified in
modprobe.conf will be used.*
Is the last sentence means that I cannot do that?
Thanks.
