[Lustre-discuss] Can lustre be a client on CentOS 5.3?

[Ms. Megan Larko]

Hi,

I'm building some new machines onto which I'd like to mount lustre
from our OSS of lustre version 1.6.4.3.
The new machines is CentOS 5.3.   The default CentOS 5.3 kernel is
2.6.18-128.  I couldn't get lustre to mount on that version so I
installed  2.6.18-92.1.17.el5 from rpm and successfully booted into
that kernel.

I cannot mount any lustre disks on this system as the client.  The
"modprobe lustre" command fails.  There is indeed a module for it in
the /lib/modules/2.6.18-92.1.17.el5  directory but using it gives many
errors (in attached text format file).  I have the impression that I
am missing something obvious.  I'm not certain what.  I am hoping the
List can enlighten my "Doh!" Homer-Simpson-esque moment.

Distro: CentOS 5.3
