Hi all, Nathan.
Included you'll find a little python script that just breaks the FS in a
matter of seconds.
We are a data shop, we eat disks for breakfast, lunch and dinner. For
some testing purposes, I created a little script for filling 2-5-10 TB
with an almost identical structure we are using for our data aquisition
backends. Bonnie and the likes end their tests where we want to start.
In there some comments that could be plain wrong, feel free to shoot at
it.
**Disclaimer :
I'm NOT an FS expert
I'm NOT a programmer
;-)
