An elected leader writes a quorum block showing that it's elected before it assumes exclusive access to the device and starts bringing up the server. This lets another later elected leader find and fence it if something happens. Other mounts were trying to connect to the server once this elected quorum block was written and before the server was listening. They'd get conection refused, decide to elect a new leader, and try to fence the server that's still running. Now, they should have tried much harder to connect to the elected leader instead of taking a single failed attempt as fatal. But that's a problem for another day that involves more work in balancing timeouts and retries. But mounts should not have tried try to connect to the server until its listening. That's easy to signal by adding a simple listening flag to the quorum block. Now mounts will only try to connect once they see the listening flag and don't see these racey refused connections.
