In your /etc/modprobe.conf add the following line and replace X with the num of your eth interface.
options lnet networks="tcp0(ethX)" -Aaron Jim Albin wrote:
I am trying to install lustre on a single system with multiple ethernet interfaces. LNET appears to map it to eth3 if it is up regardless of the node name or ip address in the XML config file. (eth1 and eth2 are also up) This is why the single system test on the loopback or localhost was not working, lctl list_nids shows the ip address of eth3. If I use the name that maps to eth3 for the config file, everything works. If I ifconfig eth3 down and use the node ip or name for eth1 it also works. I want to use the eth1 interface without disturbing eth3. The installation manual mentions LNET will try to use all available interfaces in the Chapter 2 New Schema section. How do I get it to only use a specific interface (eth1 instead of eth3)? Thanks for any advice.
