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

1. Install the kernel-devel and rpm-build packages for your kernel. Be sure the compile node is running this kernel.
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'
