You don't do anything else with RAID1 or 5 or whatever: You add code to reduce the impact of a single disk failure. You add new points of failure to reduce the impact of other points of failure there, too. In this case here, you add code (the RAID0 or LVM code, whatever you like more) to reduce the impact of two sector read errors on two disks. Of course the new code can contain new points of failures. It's as always: know the risk and decide :) regards, Mario -- <jv> Oh well, config <jv> one actually wonders what force in the universe is holding it <jv> and makes it working <Beeth> chances and accidents :) - 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
