Lustre is a scalable, secure, robust, highly-available cluster file system. it is maintained by cluster filesystems, inc. and available from http://www.lustre.org

lustre servers require a number of patches to the core linux kernel, mostly to export new functions, add features to ext3, and add a new locking path to the vfs. this package provides these patches for kernel versions 2.6.18, 2.6.21 and 2.6.22 on i386, amd64, powerpc and ia64 architectures.

for lustre clients, you will also need to build a lustre-modules package, using the lustre-source package and module-assistant.
