I've seen drives (mainly Samsung) that locked up the whole IDE bus after some simple (subsequent) sector-read- errors. And with strange IDE drivers (like PDC202XX_NEW) this could also escalate to whole-machine freezes - I've also seen this and had to play hardly with device-mapper's dm-error target to work around this :) So IMHO at least the default behaviour should stay as it currently is: if a drive fails, do never ever touch it again. Perhaps, you could make such a "FAILING" feature somehow configurable (perhaps even on a per-mirror base) in order to allow users to enable it for drives they *do* know they don't show up such a bad behaviour. regards Mario -- Independence Day: Fortunately, the alien computer operating system works just fine with the laptop. This proves an important point which Apple enthusiasts have known for years. While the evil empire of Microsoft may dominate the computers of Earth people, more advanced life forms clearly prefer Macs. - 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
