Yep, thx for mentioning, almost forgot about "smartd", soon after
trying it out again, while the box I'm currently working on was
already completely tossed, perhaps I wanted to reboot anyway?
Remembered why, smartd didn't really worked for me and almost
always took the complete system down to a grinding halt.;(

Anyway, there's only this box with a 3ware controller, so I don't
really need this tool and will happily forgo on it.

A cron job parsing the output of:

 tw_cli info c0 drivestatus

Works much more reliable, while doing the same, sending a mail if
there's a drive failure.
