FENCE_AGENT(8) System Manager's Manual FENCE_AGENT(8)

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

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.

Disable logging to stderr. Does not affect --verbose or --debug-file or logging to syslog.
Verbose mode. Multiple -v flags can be stacked on the command line (e.g., -vvv) to increase verbosity.
Level of debugging detail in output. Defaults to the number of --verbose flags specified on the command line, or to 1 if verbose=1 in a stonith device configuration (i.e., on stdin).

Power on machine.
Power off machine.
This returns the status of the plug/virtual machine.
List available plugs with aliases/virtual machines if there is support for more then one device. Returns N/A otherwise.
List available plugs with aliases/virtual machines and their power state if it can be obtained without additional commands.
Check the health of fence device
