The STONITH Story

Lars wrote a story to illustrate why you need STONITH. The story being about three hundred words long, a picture being worth a thousand words, and assuming one frame in a comic counts as one picture, between us we now have 8,300 words on why you need STONITH. Hopefully that should be enough words to convice anybody.

The Scenario

Bad Outcomes


I do not need STONITH or have disabled it

I used the null mechnaism intended only for testing

I used an ssh-based mechanism

Good Outcomes


A poison-pill mechanism with hardware watchdog support

Talk to a network power switch etc. to cut the power
