fence_compute: Fence agent for the automatic resurrection of OpenStack compute instances

NAME

fence_compute - Fence agent for the automatic resurrection of OpenStack compute instances

DESCRIPTION

Used to tell Nova that compute nodes are down and to reschedule flagged instances

fence_compute accepts options on the command line as well as from stdin. Fenced sends parameters through stdin when it execs the agent. fence_compute can be run by itself with command line options. This is useful for testing and for turning outlets on or off from scripts.
