Nevis particle-physics administrative cluster configuration

Line: 6 to 6
Archived 20-Sep-2013: The high-availability cluster has been set aside in favor of a more traditional single-box admin server. HA is grand in theory, but in the three years we operated the cluster we had no hardware problems which the HA set-up would have prevented, but many hours of downtime due to problems with the HA software. This mailing-list post has some details.
 This is a reference page. It contains a text file that describes how the high-availability pacemaker configuration was set up on two administrative servers, hypatia and orestes.
