Hi,<br>
<br>
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.<br>
<br>
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.<br>
<br>
From my readings in the luster 1.8.7 manual, I got:<br>
<br>
7.1.1 Modprobe.conf<br>
Options under modprobe.conf are used to specify the networks
available to a node.<br>
You have the choice of two different options – the networks option,
which explicitly<br>
lists the networks available and the ip2nets option, which provides
a list-matching<br>
lookup. Only one option can be used at any one time. The order of
LNET lines in<br>
modprobe.conf is important when configuring multi-homed servers. <b>If
a server<br>
node can be reached using more than one network, the first network
specified in<br>
modprobe.conf will be used.</b><br>
<br>
Is the last sentence means that I cannot do that?<br>
<br>
Thanks.<br>
<br>
