[Lustre-discuss] fstab mount fails often

OK, I started monitoring the switch - maybe I have to replace it though.
I am reluctant to do so, as I am not *sure* that it's the switch. 

I guess our overall network layout is bad - it's a single network,
single interface gbe network without any routing happening. Maybe the
switch just gets overloaded...

I realized that I did not give any parameters to the lnet module. Might
this have been a problem? If yes, why did it work at all?

Anyways, I added a simple

	options lnet networks=tcp0(eth0)

to my modprobe.conf on my clients (I had it already on the servers).

Thanks
