Thanks to Patrick for providing me a way to get this work. It worked and the build was created.

Now, I am struck with another problem when building the new kernel as RPM. :(

# make rpm (problem when build is being created in this step)

 LD [M]  drivers/isdn/hisax/hisax_st5481.o

  LD      drivers/isdn/built-in.o

make[2]: *** [drivers] Error 2

error: Bad exit status from /var/tmp/rpm-tmp.lWkmKN (%build)

RPM build errors:

    Bad exit status from /var/tmp/rpm-tmp.lWkmKN (%build)

make[1]: *** [rpm] Error 1

make: *** [rpm] Error 2

I googled and someone mentioned to add "%define __debug_package %{nil}" to beginning of kernel.spec file.

Any idea why this is happening. I am clueless. Tried 5 times atleast now. Same error everytime. :(

Hi,

I am trying to build and install Lustre on CenOS 6.6. I am following the steps detailed in Intel wiki - https://wiki.hpdd.intel.com/pages/viewpage.action?pageId=8126821

My kernel:
[centos@centvm1 ~]$ uname -a
Linux centvm1 2.6.32-504.1.3.el6.x86_64 #1 SMP Tue Nov 11 17:57:25 UTC 2014 x86_64 x86_64 x86_64 GNU/Linux

I used EPEL 5 as mentioned in step 3 and to install the kernel source, I modified the build number (from the one given in wiki page) to my current build.
When I'm trying to prepare the kernel source using rpmbuild, it is always getting struck and not getting completed. Last few messages:
###
###     rngd -r /dev/hwrandom

Has anyone ever faced this issue while installing Lustre on CentOS 6.6??
