[lustre-discuss] Issue with lnet showing network down lustre 2.5.3

[Kurt Strosahl]

Good Morning,

   I've encountered an unusual issue when upgrading a lustre client from 1.8.7 to 2.5.3.  The client installed, but when I start the lnet service it does not come up (all the modules load).  When I run a service lnet status it shows the following error:

sudo service lnet status
cat: /proc/sys/lnet/routes: No such file or directory
loaded

The box has a qdr ib card and a 10 gig ethernet card.  It is running centos 6.2 with the lustre client compiled on the box.

~> rpm -qa | grep lustre
