Raid 10 defaults to having 2 duplicate copies, and so can withstand the failure of exactly one disk. If two disks fail, it does not matter which two they are, the array has failed. You can increase it to 3 copies so you can build an array of any size ( 4, 6, 8, whatever ) that can withstand exactly 2 failed disks, in any combination. -- 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
