[Lustre-discuss] help with lnet routing

[Frank Riley]

I'm trying to set up lnet routing for our system, and it's a bit unique. I'm not sure how to do it. I am trying to route from workstation clients to the internal infiniband network of the cluster. Here is the setup:

Lustre router:
192.168.20.63 ib0
10.1.4.151 eth1

Client
10.1.10.209 eth0

For non-Lustre tcp on the client, addresses 10.1.0.0/16  on eth0 route through 10.1.0.1.

My lustre lnet config is as follows:

options lnet ip2nets="o2ib 192.168.20.*; tcp(eth1) 10.1.4.*; tcp(eth0) 10.1.*.*" \
         routes="tcp 192.168.20.63 at o2ib; o2ib 10.1.4.151 at tcp"

This of course isn't working. From the router, I can lctl ping 10.1.4.151 at tcp, but the client cannot ping the router. I'm guessing the routing from 10.1.10.0/24 to 10.1.4.0/24 is causing the problem, but I don't know how to make it work. Any suggestions?
