Yes, it's a stateful partition merge, and I think /var/log/messages should have mentioned something about that. When a node is partitioned from the others (e.g. network disconnected), it has to be cleanly reset before it's allowed back. "cleanly reset" typically means rebooted. If it comes back without being reset (e.g. network reconnected), then the others ignore it, which is what you saw.
