[Lustre-discuss] lustre 1.8.5 client failed to mount lustre

[Weilin Chang]

I agree with your observation. My purpose is to run Lustre on a 32 bit Linux system. The latest Lustre release does not support kernel patch for 32 bit Linux system. I don't know how well to generate a 32 bit Linux kernel from a 64 bit Linux system without having other problems. I think the older Lustre release which had been tested and should be ok to use it.

Do I need to patch my Linux from version 2.6.18-194.e15 to 2.6.18-194.17.1.e15 in order to work with Lustre 1.8.5?

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.
