Under each node will be an SQLite file, which should remain in consensus. You can create clusters of any size, but clusters of 3, 5, and 7 nodes are most practical.

If a node needs to be restarted, perhaps because of failure, don't pass the `-join` option. Using the example nodes above, if node 2 needed to be restarted, do so as follows:
