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 |

I noticed that nobody has commented… and this cartoon is rather creative (it sorta made my evening). So… thank you for this. Do you think you might try doing cartoons for other technical topics? It’s certainly inspired me to consider trying it – just for fun.
Thanks, glad you liked it! And you’ve just reminded me, I never published the drawing I did during this presentation at linux.conf.au 2011:

I must upload the PDF of that.
Anyway, yes, I’m sure I’ll do drawings/cartoons for other technical topics, I’m just not sure exactly what, or when yet. I have to manufacture more spare time somehow. It’s definitely a fun way to spend an evening though. Highly recommended
I love it it’s really funny
