perhaps this helps http://www.idimmu.net/2008/01/08/High-availability-with-LVS-using-LVSadmin http://www.drbd.org/users-guide/ch-gfs.html https://blog.devnu11.net/2008/04/ha-mit-debian-lenny-drbd8-ocfs2-heartbeat-pound-http-und-mysql/ cant get GFS run on ubuntu ( maybe my fault ) didnt test dovecot and postfix setup implemented in the ha-lb-cluster yet ( but ocfs was reported to work nice with dovecot deliver as far i remember), i used only apache http service for testing, but that worked nice in a vmware testing field with 4 servers ( 2 redundant loadbalancer and 2 Ha Servers ) -- Best Regards MfG Robert Schetterer Germany/Munich/Bavaria
