Basic guide to deploying a simple three-node Lustre cluster on Centos 7.
Updated fork of joshuar/Three-Node-LustreFS-Cluster-Quickstart.md, which was based on Intel's How to Create and Mount a Lustre Filesystem.
(Note: I am a newbie to Lustre so this overview is extremely light and hopefully what depth there is isn't full of mistakes!)

A collection of container images I use for admin tasks or troubleshooting in environments such as CoreOS where quite often the one or other thing is not available or I can't be bothered to install stuff.
Good old netcat:
