Hi, Is there a way in clustercontrol to specify which postgresql node is the preferred node to promote to master in case of a failure?

I've read about whitelist and blacklist, but those limit what can be promoted, not set a weight, from what I understand.

  Hello,

  In fact, whitelist can be used for this purpose. If you have a whitelist created, ClusterControl will failover to the nodes in the order they appear in the whitelist.

  That's good to know, thanks for your response, I might have missed this probably thet they are promoted in order.
