High-Availability Linux Tutorial(s)

This tutorial was jointly presented by Alan Robertson and Lars Marowsky-Bree.

Lars covered the basics of configuring an HA system, with specific details on how to configure the Linux-HA system for a typical configuration.

Lars also covered general rules for configuring HA systems, and how one goes about configuring proper redundancy in order that the HA software can make the services highly available.

Alan covered the generic plugin system, "PILS", the generic IPC code, writing resource scripts, custom IO fencing (STONITH) modules and communication modules, using the heartbeat messaging system for cluster communications, and touched on the Consensus Cluster Membership layer, and the SAF APIs.
