WIndows Cluster Active/passive nodes.
1- When windows cluster is made up of 2 nodes, one passive and one active it makes sense that when the active has issues the resources will fail over to the passive node that will become the new active node and the old active node will become the new passive node.
2- What about the cluster that is made up of 3 Active nodes and 1 passive node. Does that mean the passive node is used only if all 3 active nodes fail?
3- there are some environments wher windows clusters don't have passive nodes, ie, 3 active nodes with no passive nodes. how does this cluster function in matter of failover.
Thanks

Again: forget about "active/passive nodes", except for a snapshot consideration. It's all about owning resources and keeping them online. One node does not take over for another node. One node only takes over resources of another node.
If a node reboots and comes back online, it depends on the failover/failback strategy configured for the resource group. A resource group can be configured to just stay on the current node, or it can be configured to automatically fail back once the node is online again.

in my example about 3 active nodes , the resources are distributed among 3 nodes.
what will happen when node3 accidentaly reboots ? will the owned resources move randomly to another node ? what will happen when the node3 is back up online, will it automatically take ownership of the resources it owned ?

when you say "Preferred Owner" .
Did you mean Possible Owners:
Because we have 2 node windows 2003 print cluster, if I go to Active resources and select properties of any resource, in General tab I see a field named, Possible Owners:

if I have 3 nodes in the cluster .can I manually assign the ownership of resources 1,2,3 to node1
and resources 4,5 to node 2 and resources 6,7,8 to node3 ?
in this case are all 3 nodes considered active nodes?
what if node3 reboots then comes back, what will happen to the resources it has previously owned?
