Hello. We are currently using a Postfix master/master 2 node cluster, load-balanced with ldirectord as a resource in Pacemaker/OpenAIS.
Seems very stable and works well so far. We use SLES11 HAE. I've attached the config I use. HTH. Darren -----Original Message----- From: [email protected] [mailto:[email protected]] On Behalf Of Ciro Iriarte Sent: 14 September 2009 17:30 To: General Linux-HA mailing list Subject: [Linux-HA] eMail server cluster Hi, i'm planning to build a postfix+cyrus Active/Active cluster and would like to know if anybody has done something similar. My main doubt is about using ClusterIP or a loadbalancer with LVS in front of the two nodes. LVS would imply a third machine and i'm not sure how the origin of the outgoing connections (IP address) is handled by ClusterIP. Any comments?. -- Ciro Iriarte http://cyruspy.wordpress.com -- _______________________________________________ Linux-HA mailing list [email protected] http://lists.linux-ha.org/mailman/listinfo/linux-ha See also: http://linux-ha.org/ReportingProblems
