I thought of this one day and was wondering if it is even possible, so here goes. Disclaimer: I have no system that I actually want to do this on, it was merely a hypothetical thought Let's say I have a working 4 drive raid-5 array and I want to add 4 more drives of the same capacity and convert it to raid 50. So I assume first I would set up the new blank array as a raid 5 then setup stripping across the 2 raid sets. Now I think the raid 0 setup would tell me to initialize everything but I was thinking that raid 5 reshapes the arrays and stripes when you modify it (add/grow a drive) so why couldn't that same algorithm be applied in this scenario. Again, this was just a hypothetical. I doubt its possibly right now (maybe I'll be surprised) but then again maybe it will inspire one of you to actually make this possible in the future.
