How to Add a Kernel Module to a Software Image initrd In 4 Steps

By Robert Stober | April 04, 2015

There are times when you need to customize the operating system that servers in your cluster are running in order to enable some special capability. One example is enabling a server to take advantage of accelerator or GPU hardware by installing a kernel module. Bright does this automatically for some of the most popular devices, like NVIDIA GPUs, but you may have other needs. For example, kernel modules often are required to control particular storage, network, or other devices.

Carrying out such low-level modifications on a server can be risky. If done incorrectly, kernel modifications could cause the server to fail. The risk is compounded in a clustered environment since different servers may need different kernel modules to load every time they are restarted.

Fortunately, Bright Cluster Manager can minimize the risk out of installing kernel modules, and automate the process so that the cluster’s operation remains consistent.

Here’s how it’s done:
