Are there any plans in the near future to enable growing RAID-6 arrays by

I have a 15x500GB - drive unit and I need to add another 15 drives into
it... Hindsight is telling me that maybe I should have put LVM on top of
the RAID-6, however, the usable 6TB it yields should have been enough for
anyone...
Well, if you are doubling the space, you could take this opportunity to put
lvm on the new disks, move all the data, then put in the old disks as a pv,
extending the lvm space.
Now why didn't I think of that. *thud*
I really wouldn't recommend having a 30-disk raid6, imagine the rebuild time
after a failed disk..
There is that - it would give me 2 disks (ie. 1TB) more space though...
This isn't a performance limited server though, it's an off-site backup
box, so it just has to be reasonably reliable.
Thanks!
