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

1. Install the kernel-devel package for your kernelBe sure the compile node is running this kernel
2. Obtain the Lustre .src.rpm (from the SRPMS section of the download site)
3. On the build node, run the command:

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

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