For ICH5 and all other controllers (non-AHCI) of course, I've always seen md mark it faulty on a bad disk/sector/etc.
ICH7 (ahci) does not. At least not a whole disk dieing, don't know about bad sectors.
I thought you were just trying to mark it faulty manually for the purpose of rebuilding it.
Ah, no I wasn't :) C. - To unsubscribe from this list: send the line "unsubscribe linux-raid" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
