NB> Or maybe the drive is failing, but that is badly confusing the NB> controller, with the same result. NB> Is it always hde that is reporting errors? for now - yes; but a few months ago for a short period of time hdg and hdh also have been reported with errors, but this went away quickly and never occured again. NB> With PATA, it is fairly easy to make sure you have removed the correct NB> drive, and names don't change. hde is the 'master' on the 3rd NB> channel. Presumably the first channel of your controller card. I know; what I meant was: I'd like to make sure that I remove the one drive that md thinks is faulty - I want to avoid removing a healthy drive, leaving md with one broken drive and two healthy ones which isn't good for a raid5. but in this case, hde rather certainly is the troublemaker. NB> No, a faulty drive in a raid5 should not crash the whole server. But NB> a bad controller card or buggy driver for the controller could. this seems to be the case here. guess its time to shop for a new server. tnx. ------------------------------------------------------------------------------ Rainer Fuegenstein rfu@xxxxxxxxxxxxxxxxxxxxxxxx ------------------------------------------------------------------------------ "Why are you looking into the darkness and not into the fire as we do ?", Nell asked.
