As I see the problem, the definition of what is a "failed drive" is different from sysadmin's point of view and from md's point of view. Md freaks out on every single unrecoverable read error, but these usualy do not indicate a completely failed and dead drive. What needs to be done is to give md some more knowledge about disk errors, disk behaviour at dying and possibly integrate it in some way with smartd. This has been requested every now and then at least for the last three years, however nobody started to work on something like this, at least I'm not aware of any such activity. How exactly this could / should be acomplished is an interesting topic too. -- Jure Pečar http://jure.pecar.org/ - 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
