In a two node cluster both nodes have to be available. What you should have done was to remove the second node while the control volume was still available. "remove-node". Then your setup would have become a 1 node setup from a leader election point of view (+ the satellite), and would have started. The easy way out is to also "uninit" the first node and start from scratch. If the control volume already contains useful information like lots of already configured drbd resources, you can force a win of the leader election ("reelect --force-win"), "remove-node -f" the second, "restart -q" to cleanly start it as a single node cluster, "add-node" the second one.
