prevents it from directly recognized by file system code . I was wondering if Split RAID block devices can be made to be unaware to the RAID scheme on top and be fully mountable and usable without the raid drivers (of course invalidating the parity if any of them are written
Well, there's two basic cases: 1) You have one device and you're adding a parity device - which is basically just creating a raid-1 mirror when you get down to it. 2) You have some collection of devices in a stripe/concat/whatever, and are adding a parity device. This only works if the existing stripe/concat is already functional *without* the parity device (which implies that said stripe or concat has to be an already-supported structure)
