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.

Yes, I checked it but it seems I still need three nodes - 2 for storage and one smaller for arbiter.
Is it safe to deploy it only on two nodes?
Am I wrong?
