The most important question is why are you starting with this very old
1.8.5 release from 3 years ago instead of a newer release like 2.1.6 or
2.4.1?
You will definitely find better support for newer kernels with newer
releases,
as well as a better chance that someone will be able to fix your problem.

My first guess is that your client network is not configured correctly,
since
it has a hostname of "localhost".  Second guess is that the Lustre modules
are not properly matched with your kernel and they are not loading at all.
