fence_compute (8) Linux Manual Page
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.
