_Archived 20-Sep-2013_: The high-availability cluster has been set aside in favor of a more traditional single-box cluster. 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. [[http://www.gossamer-threads.com/lists/linuxha/users/87132][This mailing-list post]] has some details.

Here are the pages that documented the state and the diagnostic procedures for the HA cluster when it existed:

   * The [[AdministrativeDualPrimaryCluster][administrative cluster]]:
      * [[PacemakerDiagnostics][basic diagnostic procedures]];
      * [[http://www.nevis.columbia.edu/cluster-status.html][cluster resource status]];
      * [[PacemakerDualPrimaryConfiguration][pacemaker configuration]] for the very brave.
