When you give mdadm a collection of drives to turn into a RAID array, use bases the size of the array on the smallest device. You might want to make it a little smaller still in case you have to replace a device with a slightly smaller device (it happens). You can use "--size" to reduce the used space a little further if you like. NeilBrown
