Fencing
Fencing is the process of locking resources away from a node whose status is uncertain.
There are a variety of fencing techniques available.
One can either fence nodes - using NodeFencing, or fence resources using ResourceFencing. Some types of resources are SelfFencingResources, and some aren't damaged by simultaneous use, and don't require fencing at all.
