Please excuse me if this is documented and I failed to find it. I have been investigating ha-linux to provide Business Continuity in our mail server. Currently we have a single mail server in our main office. We would like to set up a second server in a geographically different location and make a cluster of 2 nodes so that we can continue doing business if one fails.
As far as I can tell ha-linux with Pacemaker is ideally suited to this. My question is around how the cluster handles requests to the mail server(s). Can anyone suggest some appropriate reading for where/how this is handled? My concern is that should there be a failure at the location that is receiving the requests how does it know to use the second node? Is this typically done through zone files and an priority? Obviously I am missing some important reading here because it would seem to me that there could still be a single point of failure and that doesn't seem right. What am I missing? Please and thanks -- Paul O'Rorke _______________________________________________ Linux-HA mailing list [email protected] http://lists.linux-ha.org/mailman/listinfo/linux-ha See also: http://linux-ha.org/ReportingProblems
