If the lustre-client rpms need to be rebuild against a different client kernel, follow this proceedure.

Procedure

NOTE This procedure assumes you are using a RPM based distribution. For example RHEL or CentOS.

1. Install the following packages:
   • kernel-devel
   • rpm-build
   • make

     If you are not currently booted into the kernel provided by kernel-devel pacakge review the trouble-shooting section below.

2. Obtain the lustre-client .src.rpm (from the SRPMS section of the download site).
3. On the build node, run the command:

# rpmbuild --rebuild <lustre version>.src.rpm

NOTE The resulting RPMS may be named 'lustre-modules' rather than 'lustre-client-modules'

Trouble-shooting

Building against a different kernel.

To build against a different kernel to the one currently running, you need to provide the chosen kernel to rpmbuild. For example:

rpmbuild --define 'kversion 2.6.32-220.4.1.el6.x86_64' --define 'kdir /usr/src/kernels/2.6.32-220.4.1.el6.x86_64/' --rebuild lustre-client-2.1.0-2.6.32_131.6.1.el6.x86_64_g9d71fe8.src.rpm
