Hello everyone. I was wondering if someone could help me out with a requirement for a High Availability DB-Server. I had looked at the DBs built in replication systems but they were just for the DB contents. Everything else around it would need extra effort. While I had also thought about using virtualization (we also use VBox, but not for HA) the HA requirement would mean the server could only be alive on one machine in the cluster, and if that one fails, pop up (with as little loss as possible) on another one. The idea being * if a customer only wants one machine: install the image directly on the host. * if a customer wants a HA system, use a virtualized setup with a floating server (if that will even work) The thing is: a) I was deemed 'the expert' (because they could not find anyone else) to do this but my knowledge is really limited. b) to somehow have a HA system that is easily installable at a customers location by a 'service engineer' (some setup steps could be automated but in general, the easier the better). A colleague of my suggested KVM would be just the tool for it, but I have yet to figure out how to get it to magically appear on cluster node 2 if the 1st fails (I am using proxmox based on the howto) Also Xen was named to have this feature. I have looked at the HowTos (excellent work btw!) but am unsure what I really need and what not. Why do I need DRBD f.i.? thanks in advance!
