I'm about to create a RAID1 file system and a strange thought occurs to me: if I create a two-disk RAID5 array then I can grow it later by the simple expedient of adding a third disk and hence doubling its size.
Is there any real down-side to this, such as performance? Alternatively is it likely that mdadm will soon be able to convert a RAID1 pair to RAID5 any time soon? (Just how different are they anyway? Isn't the RAID4/5 checksum just an OR?)
