Hello Andreas,
Thanks for your email. I believe basic functionality of Lustre 2.3 should work even it has some issues. Well, I installed all the RPMs and patched the kernel, following is the output of all the packages, is there anything else which I need to install?
I build all these packages first on my local machine.
kernel-2.6.32.lustremaster-1.x86_64
lustre-2.3.0-2.6.32.lustremaster.x86_64
lustre-tests-2.3.0-2.6.32.lustremaster.x86_64
lustre-ldiskfs-3.3.0-2.6.32.lustremaster.x86_64
e2fsprogs-1.42.7.wc1-7.el6.x86_64
e2fsprogs-libs-1.42.7.wc1-7.el6.x86_64
I have all required configuration, e.g. selinux=disabled. Created /etc/modprobe.d/lustre.conf file with "options lnet networks=tcp", stop firewall services etc.
But, when I run : "mount -t lustre /dev/sdb/ /mnt" on an OSS server to mount OST device, I get following error:
Jul 23 17:54:42 lustre-5 kernel: LDISKFS-fs (sdb): mounted filesystem with ordered data mode. quota=off. Opts:

Are the lustre modules loaded?
Check /etc/modprobe.conf and /proc/filesystems
[root@lustre-5 lustre]# Jul 23 17:54:42 lustre-5 kernel: Lustre: server umount lustre-OST0000 complete
Jul 23 17:54:42 lustre-5 kernel: LustreError: 10237:0:(obd_mount.c:2569:lustre_fill_super()) Unable to mount (-19)
Thanks,

Not sure why you are installing Lustre 2.3 at this point (it is not a release with ongoing maintenance), when 2.4 is available (which will have a support stream).
In any case, it seems you didn't install the Lustre patched kernel along with your RPMs, which is required on the server.
Cheers, Andreas
Hello,
I am able to install luster 2.3 now, but I am getting following error:
FATAL: Error inserting obdfilter (/lib/modules/2.6.32.lustremaster/updates/kernel/fs/lustre/obdfilter.ko): Unknown symbol in module, or unknown parameter (see dmesg)
obdfilter: Unknown symbol security_inode_unlink
This could be due to the following warning while installing luster-modules:
[root@lustre-5 lustre]# rpm -ivh lustre-modules-2.3.0-2.6.32.lustremaster.x86_64.rpm
Preparing... ########################################### [100%]
1:lustre-modules ########################################### [100%]
WARNING: /lib/modules/2.6.32.lustremaster/updates/kernel/fs/lustre/obdfilter.ko needs unknown symbol security_inode_unlink
Any insight?
