No it is not safe to only use two nodes as you can end up with split brain. So two nodes and an arbiter node is needed. The arbiter doesn't need to be that fancy. Also the installer if installed with gluster as hosted storage (storage for the engine) will complain if replica is less than 3.

You need replicated gluster storage for that. So that one part of the storage can go down but two others still keep on running. And you need to set the threshold so that a quorum of 2 is sufficient (if you have replica 3). If the storage volume is offline. It would be the same as the same

The norm is to have a cluster with shared storage. So you have 3 to 5 hardware noed that shares storage for the hosted engine. That shared storage is in sync. So you don't have one engine per physical node. If one hardware node goes down the engine is restarted on another node with the help
