Just found out about Proxmox and have a few questions I’m coming from a Windows Server with Hyper-V background where a couple servers were configured to failover to each other.

From what I’ve read so far Proxmox can do similar with its high availability option.

Where I’m confused is I keep seeing mention that Proxmox also needs a shared storage location for the VMs like a NAS. If that’s true then doesn’t the NAS still become a single point of failure? Or am I misunderstanding something?

My goal is a cluster for VMs such that any node can fail without crashing VMs or losing data.

Any help understanding is much appreciated.
