When building a cluster of 4 nodes for Failover Cluster with Hyper-V on top of a hyperconverged setup using S2D, my understanding is if one host goes down, the other 3 nodes pickup the VMs. Storage of that VM is moved to the host that owns that VM.
Now if I were to add a 5th node, does the new storage presented not have redundancy until I add 3 more nodes or does Windows S2D move data around other hosts to build resiliency?
This would be setup with a 3-way mirror.
In short, I'm looking to deploy this in production once it's released, but I'd like to understand more of how adding nodes works in the cluster.
