You can't have a hard link between files in different drives[0]. mmddfs is probably copying instead of linking, even if it receives a ln call, when it determines that each file must end up in different disks. For your use case, LVM seems more adequate: you'll have only one filesystem, even if at disk level it's stored in two disks.
