Question I have. I know in a 2 node config, if one node goes down and you start a vm you get a quorum error and you cant start the VM/s. I'm pretty sure this is because you need 3 nodes for (voting I think?) redundancy.
The issue I have is I have 2 servers and a shared storage server.
1. Is it possible to use the shared storage raid for an additional quorum disk, so that if one of the servers goes down I can still access the Vm? How to?
2. My plan is to put the 2 servers + shared storage server (readynas 3100) in our data center, run it for a bit and then add the 3rd server to the node when I can migrate off an existing machine, then add others from there if needed. If using a quorum on shared storage is possible would this work? Could I add additional machines and when I get to 3,4,5 and can I remove the quorum form the shared storage all together after I have 3 server nodes in place.
3. Is this a good approach? Any drawbacks.
