runmmfs: Unable to verify kernel/module configuration.

Taken from GPFS Determination Guide

If you are running General Parallel File System, you may encounter the error found at/var/adm/ras/mmfs.log.latest

 This problems occurs if:

1. The portability layer is not built.
2. The GPFS kernel modules, mmfslinux and tracedev, are built with a kernel version that differs from that of the currently running Linux kernel. This situation can occur if the modules are built on another node with a different kernel version and copied to this node, or if the node is rebooted using a kernel with a different version.
