[Lustre-discuss] Selection of kernel options for the distributed Lustre kernels

I reinstalled the pre-built kernel from the rpm as available from the 
Lustre website and installed the kernel-ib package as well:

-->
[root at host ~]# rpm -qa | grep kernel-lustre
kernel-lustre-smp-2.6.18-128.1.6.el5_lustre.1.8.0.1

[root at host ~]# rpm -qa | grep kernel-ib
kernel-ib-1.4.1-2.6.18_128.1.6.el5

[root at host ~]# uname -a
Linux host 2.6.18-128.1.6.el5_lustre.1.8.0.1smp #1 SMP Thu Jun 18 
17:06:38 MDT 2009 x86_64 x86_64 x86_64 GNU/Linux
<--

It seems that the iSCSI modules cannot be loaded:

-->
[root at host ~]# modprobe scsi_transport_iscsi
FATAL: Module scsi_transport_iscsi not found.
<--

That's probably as modprobe will check in
/lib/modules/2.6.18-128.1.6.el5_lustre.1.8.0.1smp
not in
/lib/modules/2.6.18-128.1.6.el5
where kernel-ib installs its modules

So, insmod maybe?

-->
[root at host ~]# insmod 
/lib/modules/2.6.18-128.1.6.el5/updates/kernel/drivers/scsi/scsi_transport_iscsi.ko
insmod: error inserting 
'/lib/modules/2.6.18-128.1.6.el5/updates/kernel/drivers/scsi/scsi_transport_iscsi.ko': 
-1 Invalid module format
<--

Am I missing anything obvious here?

TIA,
  Arne
