KWLUG Meeting: Monday, February 6 2012

Aden Seaman will discuss a number of technologies and tricks he discovered in setting up a two-node high-availability cluster in his own home. He will give an overview of how DRBD block device mirroring, OCFS2 shared disk filesystems, GlusterFS cluster filesystems, clever network configuration, and the Pacemaker and Corosync cluster resource tools can work together to make a high- availability computer cluster. He will also briefly touch on integrating User Mode Linux virtual computers, an Asterisk PBX, and a DSL and firewall setup with the cluster. Finally he will give a live demonstration of his system.
