I'm no expert in this (!) but I passed it on to Alan Robertson (architect of the Heartbeat project), who noted another way to deal with some of the underlying issues that works well for some folks: Cluster IP (using a single IP address and multicast mac addresses). It is described in a book that Alan recommends by Karl Kopper that probably covers other things also related to your interest: "The Linux Enterprise Cluster: Build a Highly Available Cluster with Commodity Hardware and Free Software." See http://www.linux-ha.org/ for some more information from a "heartbeat" centric viewpoint. Alan also plans to cover it at some point in his blog at http://techthoughts.typepad.com/ Neal McBurnett http://mcburnett.org/neal/ -- ubuntu-server mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-server More info: https://wiki.ubuntu.com/ServerTeam
