pacemaker does not have concept of "passive" or "master" node - it is up
to you to decide when you configure resource placement. By default
pacemaker will attempt to spread resources across all eligible nodes.
You can influence node selection by using constraints. See
https://clusterlabs.org/pacemaker/doc/en-US/Pacemaker/1.1/html/Pacemaker_Explained/_deciding_which_nodes_a_resource_can_run_on.html
for details.
But in any case - all your resources MUST be capable of running of both
nodes, otherwise cluster makes no sense. If one resource A depends on
something that another resource B provides and can be started only
together with resource B (and after it is ready) - you must tell it to
pacemaker by using resource colocations and ordering. See same document
for details.

Yes.

Yes. Node clustera is now marked as being incapable of running resource
so if node cluaterb fails, resource cannot be started anywhere.
