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.

Re: [Lustre-discuss] lustre 1.8.5 client failed to mount lustre
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? -Weilin -Original Message- From: Dilger, Andreas [mailto:andreas.dil...@intel.com] Sent: Thursday, October 17, 2013 11:06 AM To: Weilin Chang Cc: lustre-discuss@lists.lustre.org; hpdd-disc...@lists.01.org Subject: Re: [Lustre-discuss] lustre 1.8.5 client failed to mount lustre On 2013/10/16 4:45 PM, Weilin Chang weilin.ch...@huawei.com wrote: HI, I am using luster 1.8.5.
