Is this "ISPConfig multiserver setup with pacemaker and DRBD for syncing/switching with backup server" even possible? I want to have 2 servers (server1 and server2) that are running KVM hypervision, each with 4 virtual servers for web&mysql, mail, dns1 and dns2. Every virtual server will have drbd and pacemaker installed to replicate to the node on the other server (server1.web&mysql <-> server2.web&mysql2). I know that DRBD needs to have it's own partition that it replicates. So how to install to that partition and what do I have to replicate? How to configure ISPCinfig on the second server. Do I set all virtual servers on server2 to mirrors to be mirrors of the virtual servers on server1? Or do I have to install a new multiserver setup on the server2 and have it's ovn primary server with the interface? Any other thing I shold be aware of?
