I’m looking to use Haproxy backup on a series of RabbitMQ clusters, I have it working, all except for when the primary cluster returns… On failback the connections still on the backup cluster persist (causing a split brain).
Is there away to force connections to close (on the backup) if there is a failback (to primary)?
Or even if there is a way to stop a failback (auto back to primary on recovery) occur unless the service is restarted?
I’ve been through lots of docs, but all I can find it stuff saying, ‘yes it will persist’. If I can’t get this functionality the solution is a no go.
