@Tibmeister Just a minor clarification - in a non-stretched cluster, NO host would have 'Witness' role, just Master('Leader' in later builds)+Backup+Agent roles exist from a cluster-role perspective.
My understanding of it is that where witness-components and data-components get placed is based purely on storage space available on each node (e.g. if node1 and node2 have higher disk usage than node3 then node3 will get the smaller witness-component).
