What is preferred owner and possible owner in cluster?

What does it mean to have preferred owners in cluster?

The key point I want to make is that, when you set the preferred owners for a group to a subset of the nodes in a cluster, you’re not saying “I want the group to failover only to these nodes”. What you’re effectively saying is, “please reorder the nodes such that these are at the front of the list.”

Do you need failover cluster for always on availability groups?

Deploying Always On availability groups requires a Windows Server Failover Cluster (WSFC). To be enabled for Always On availability groups, an instance of SQL Server must reside on a WSFC node, and the WSFC and node must be online. Furthermore, each availability replica of a given availability group must reside on a different node of the same WSFC.

Which is the priority for the availability group?

The priority is first for current primary replica. This is only for the availability group resource and not for other resources. For example, dependent resources like listener, listener IP have all availability group failover nodes as possible owners.
