Hey - I was planning to do that! :-)

Seriously, yes of course, please do. That would be wonderful. It belongs 
best after "Recovering a damaged RAID" in the "When things go Wrogn" 
section, i think.

Just skim the contribution guidelines before you start, they're nothing 
onerous, just use good English and use "I" a lot, take responsibility 
for what you write. It's meant to be easy reading but informative. A 
case study of what you did would be marvelous.

I need to edit the page about that script you ran, and put a big big 
warning in front of it not to run it recklessly :-)

(Contact me off-line if you haven't got an account and have difficulty 
creating one.)
