Hello Andreas, Ulrich, Thanks a lot for your email. Can you please point me to a location where I can find the right version of Kernel for my RHEL 6.4 machine? My RHEL 6.4 is @ Kernel: 2.6.32-358.el6.x86_64 level. The download location I use for the Kernel sources is: http://ftp.redhat.com/pub/redhat/linux/enterprise/6Server/en/os/SRPMS/ and downloaded kernel-2.6.32-358.el6.src.rpm<http://ftp.redhat.com/pub/redhat/linux/e... sources. I use following link to build and install Kernel and Lustre sources and not sure what I am missing: https://wiki.hpdd.intel.com/display/PUB/Walk-thru-+Build+Lustre+MASTER+on... Can someone please provide me the correct location, luster sources location, cheat sheet for installation and configuration? Also, can someone please provide me the list of Lustre modules to check whether they are installed and running or not?

Hello Ihara, Thanks for your email. I have moved to RHEL 6.4 and Lustre 2.4. It seems that I am able to build/install and configure MGS and OSS. I was not able to install and configure Lustre OSS and MGS with pre-built RPMs so I moved to building the kernel and Lustre sources myself. Now I am going to install and configure client with building its sources. Are there any specific steps for building client RPMs? Thanks, -Upanshu -----Original Message----- From: Shuichi Ihara [mailto:sihara@ddn.com] Sent: Monday, July 29, 2013 3:13 PM To: Singhal, Upanshu Cc: Dilger, Andreas; Adrian Ulrich; hpdd-discuss(a)lists.01.org Subject: Re: [HPDD-discuss] Error Mounting OST device on OSS Server I think that is fine, but lustre-2.3 was basically tested on rhel6.3 kernel. You might need some adjustments of kernel patches for RHEL6.4. btw, What is your specific reason to build kernel it self? Why not use lustre patched kernel for servers? Do you have any other specific kernel patches out of lustre related and need to apply them? If not, as Andreas suggested, try use pre-patched kernel instead of building kernel yourself.. You can download RPMs from here.. http://downloads.whamcloud.com/public/lustre/ Thanks Ihara On Jul 29, 2013, at 3:15 PM, "Singhal, Upanshu" <upanshu.singhal(a)emc.com&gt; wrote: > Hello Andreas, Ulrich, > > Thanks a lot for your email.
