So HyperFS uses STONITH method for the metadata controller HA failover, what does STONITH mean?

STONITH is an acronym meaning "Shoot The Other Node In The Head" and by using IPMI or iLO the HyperFS software is able to control the front power button on both servers and in the event of a failover condition, one server can "pull the power plug" on the other one to shut the failing unit off.
