Hello, After reading the ISPConfig 3 clustering guide: http://www.howtoforge.com/installin...tabase-cluster-on-debian-5.0-with-ispconfig-3 I have a couple of questions. Is clustering meant to provide real-time redundancy? As in, if "server 1" goes down, would "server 2" automatically take over? If so, how does this work when it comes to DNS? The 2 servers can not have the same IP addresses. So if a website has for example the dedicated IP address of 220.127.116.11 in "server 1" and that server went down, how would ISPConfig 3 transfer the IP address data over to the other server? Or another example would be with the name servers. If "server 1" had the ns1/ns2.example.com name servers configured in its bind9 configuration, and "server 2" had ns3/ns4.example.com as its name servers, would the client's domain name need to have all 4 name servers setup on its domain name? Thanks!
