If you're using mirrored pairs, that's no problem - you'll always be adding
or upgrading a pair of drives at a time. e.g. to go from RAID-1 with a single
mirrored pair to RAID-10 with two mirrored pairs. or to add a third or fourth
or fifth ... mirrored pair of drives.
btrfs has greater flexibility in that it allows you to combine any combination
of differently sized drives, and it's easy to rebalance your data across the

And I have my doubts about whether its raid-1 or raid-10 modes are entirely
reliable either...i'm still seeing occasional reports of catastrophic data
loss with btrfs that can't easily be dismissed as user error.

"dubious" was the wrong word. "prohibited" is accurate. It's only "legally
dubious" because, as you say, it's very unlikely that Oracle or anyone else
with standing would sue.
