[Lustre-discuss] odd mount behavior

[John White]

Hello Folks,
	We've got a new client we're trying to get to mount an existing file system.  The host cluster is set up with 2 NIDs for the MDT (o2ib, tcp), same with the client.  When I try mounting via tcp (mount -t lustre -o flock n0006.lustre at tcp:/vulcan /clusterfs/vulcan/pscratch), it just hangs there indefinitely with repeated messages like:

Lustre: Request x264 sent from vulcan-MDT0000-mdc-ffff8101e39bb400 to NID 10.4.200.6 at o2ib 5s ago has timed out (limit 5s).

I'm confused why it's attempting the o2ib NID repeatedly and never tries the tcp NID... Ideas?
