That makes a lot of sense. I already have a Synology DS920+, so there’s no additional storage hardware cost on my end. The Tiny form factor is ideal for me mainly due to footprint and low noise, but total cost and idle power are definitely things I’m weighing.

Another route I’m considering is picking up just one more Tiny instead of two, and running an external Corosync QDevice directly on the DS920+ (via a lightweight Docker container) for the tiebreaker vote. That gives me a proper 2-node quorum without the hardware cost and power draw of a third physical node. Combined with the DS920+ for shared iSCSI storage, that might actually hit the sweet spot between cost, footprint, and HA.
