Lustre server machines are simple to setup with CentOS 5.5. Pre-built kernel images are available from Whamclouds build server. A number of different kernels and tools are continuasly built and tested. For this Walk-thru the centos-master-build will be used.

Prerequisite.

...

1. Identify the recent, Lustre patched, kernel.
   This can be found by either navigaing from the centoslustre-master -build page or by visiting a link the the [last successful build for x86_64| http://build.whamcloud.com/job/lustre-master/arch=x86_64,build_type=server,distro=el5,ib_stack=inkernel/].
2. Identify the most recent kernel RPM.
   Recent kernel builds are of the form kernel-2.6.18-194.17.1.el5_lustre.<buildid>.x86_64.rpm
3. Download this RPM to the machine client-10.
4. Install the kernel.

   Code Block
   [root@client-10 ~]# rpm -ivh ./kernel-2.6.18-194.17.1.el5_lustre.<buildid>.x86_64.rpm Preparing... ########################################### [100%] 1:kernel ########################################### [100%] [root@client-10 ~]#

5. Reboot
6. Verify that the new kernel has been booted:

   Code Block
   [root@client-10 ~]# uname -a Linux client-10.lab.whamcloud.com 2.6.18-194.17.1.el5_lustre.gdfe90dc #1 SMP Sun Mar 13 03:18:21 EET 2011 x86_64 x86_64 x86_64 GNU/Linux
