dlm_stonith: a proxy for fencing via stonith/pacemaker
dlm_controld can use dlm_stonith as a proxy fence agent when the stonith/pacemaker system performs actual fencing.
dlm_stonith is run by dlm_controld, and is not meant to be run manually. dlm_controld provides the options on stdin as key=val; command line options are for testing.
If fencing was successful, this program has a zero exit code. If fencing failed, this program has a non-zero exit code.
The nodeid of the target node. (stdin key is "node")
The time(2) at which the target node failed. If this option is provided, and the last fencing time is later, then a new fencing request is not made.
