thanks, I saw that. but postfix was busy sending out a huge newsletter and the HD always gets that busy during that period without crashing everything.
since I moved to this new server just a few months ago, I assumed the HDs were ok...
I'll run the Strato HW test again tonight, makes the server unreachable for two hours but at least I'll know if there is something wrong...
btw. that server runs on a software raid1 that came pre-installed on the minimal debian OS they offer. anyone has any links for raid optimizing? any parameters to tune? I haven't touched it yet...
