This means that the libcfs module is not loaded. This should be loaded on demand as needed. That implies that "modprobe -ae" is not being run after module installation, or that the modules are being installed in a directory that does not match your kernel version. If you run "rpm -qi kmod-lustre" (or "rpm -qi kmod-lustre-client" if on the client) it will report which kernel the modules were built for. This is also stored in every module, and can be seen with "modinfo lnet" and "modinfo libcfs" in the "verinfo" field. This should match the currently running kernel version reported by "uname -r".
