Hi Kevin You rightly said I am using RHEL4U4 (2.6.9-42.ELsmp) and installing luster rpm which are for 2.6.9-67. As James suggested I have installed kernel-lustre-smp-2.6.9-67.0.7.EL_lustre.1.6.5.i686.rpm lustre-modules-1.6.5-2.6.9_67.0.7.EL_lustre.1.6.5smp.i686.rpm lustre-1.6.5-2.6.9_67.0.7.EL_lustre.1.6.5smp.i686.rpm and rebooted the system with luster patched kernel
[EMAIL PROTECTED] lustre-client]# uname -a Linux ganges 2.6.9-67.0.7.EL_lustre.1.6.5smp #1 SMP Mon May 12 22:03:01 EDT 2008 i686 athlon i386 GNU/Linux And it's working now(Thanks James). I am able to read/write/delete in Lustre based mount point But still need to validate one point I was using kernel 2.6.9-42(RHEL4U4) when I implemented patch which is for 2.6.9-67.0.7. it worked for different kernel. Is there anything like backward compatibility is working this for my setup? Ideally I should have used either 2.6.9-67.0.7. kernel based OS or Lustre source should be compiled to patched 2.6.9-42 kernel. Please help me to understand. Once again I appreciate your support.

(ie, kernel modules are in /lib/modules/`uname -r`, but lustre modules are in /lib/modules/<something_else>) I note that you installed the server kernel modules, so you need kernel 2.6.9_67.0.7.EL_lustre for them to work. See my original note below on patchless clients: use lustre-client-modules RPM, with the version matching the installed kernel. With the server module RPMs, you need the lustre kernel as well.
