This is a recurring theme.  Would it be advisable to add some documentation to the website recommending zookeeper for production, and corosync only for small scale testing?

Corosync is said to support small cluster (less than 10 nodes). So in your case,
I suggest you try zookeeper, which support thousands of nodes.
