And is there any specific installation order for patchless client?
Could someone please share it with me?

Huh... :( Sorry to bug you guys again...
I am planning to make a fresh start now as nothing seems to have
worked for me. If you have any comments/feedback please share them.
I would like to confirm installation order before I make a fresh
start. From Arden's experience:
http://lists.lustre.org/pipermail/lustre-discuss/2009-June/010710.html
, the lusre-module is installed last. As I was installing Lustre
1.8, I was referring 1.8 operations manual
http://manual.lustre.org/index.php?title=Main_Page . The
installation order in the manual is different than what Arden has
suggested.
Will it make a difference in configuration at later stage? Which
one should I follow now?
Any comments?
Thanks,
CS.

Thanks Cliff.
The depmod -a was successful before as well. I am using CentOS 5.2
box. Following are the packages installed:
[r...@localhost tmp]# rpm -qa | grep -i lustre
lustre-modules-1.8.0-2.6.18_92.1.17.el5_lustre.1.8.0smp
lustre-1.8.0-2.6.18_92.1.17.el5_lustre.1.8.0smp
[r...@localhost tmp]# uname -a
Linux localhost.localdomain 2.6.18-92.el5 #1 SMP Tue Jun 10
18:49:47
EDT 2008 i686 i686 i386 GNU/Linux
And here is a output from strace for mount:

Any further debugging hints?
Thanks,
