This is what I see from the discussion forums.. This warning is because another cluster including the systems ns1 and ns2 is on the same subnet as yours. If you change this node to use either ucast or mcast, or a different port number on bcast ( in ha.cf ) , then this will go away. http://lists.linux-ha.org/pipermail/linux-ha/2006-May/019753.html http://osdir.com/ml/linux.highavailability.user/2004-11/msg00149.html Thanks, Krishnaprasad -----Original Message----- From: redhat-list-bounces@xxxxxxxxxx [mailto:redhat-list-bounces@xxxxxxxxxx] On Behalf Of Matias Villarreal Sent: Sunday, May 02, 2010 8:03 PM To: RedHat Forum Subject: Question about heartbeat log.
