Description

It would be useful to implement a tool that allowed for an administrator-controlled "forced" configuration change. This type of thing is useful as a "parachute" if, for example, 2 nodes of a 3-node configuration were permanently offline. An administrator may wish to accept whatever potential data loss occurred and force the configuration to be composed of a single node so that it could come back online and then grown back to a larger configuration size again.
