From: Indunil Jayasooriya <indunil75@xxxxxxxxx> >my task is to have 2 zimbra servers with mail.example.com with 2 ips >192.168.0.1 is the primary, I want to rsync /opt of this server to the other server 192.168.0.2. >then, primary fails, I have a backup on the other server. no data lost.... >This is what I want to achieve. but, NOT for any kind of ROUND ribbon DNS stuff.. On the server itself, as long as it is only in /etc/hosts, I think you can (be sure to have hosts: files dns in nsswitch.conf). So you mean to manualy modify your DNS to switch from 192.168.0.1 to 192.168.0.2 if 192.168.0.1 is down? Maybe have a look at the Zimbra multi server install documentation.
