As long as 2 out of 3 of them are available it should work fine. If you have 2/3 down at the same time then yes, it will not be functional.

What if I have only two nodes? Would 1/2 cause a problem?

1/2 is not HA

Quorum requires an odd number of servers. If you have 2 servers, then either one being down will cause an outage on the other.

Okay, I assumed it wouldn't be HA. I do need to rebuild my environment anyways so I'll probably rebuild under 3 node and see if that improves things.

And I should be able to simply reboot any of the 3 and it should stay happy, correct? Maybe makes sense to cordon a node.
