I have tried and tested every possible permutation of trying to replace small disks in a RAID group (or aggregate) with larger ones.
Though there seems to be promising looking methods that appear to stand a chance of working they will not. It cannot be done.

Hi all,
We have a ton of shelves with 320gb sata in them. We'd like to replace them with 1tb satas, but we have no power to power new shelves, or much space for them for that matter.
I know that if I swap out one 320gb disk with a 1tb one, the netapp will only use 320gb of the 1tb disk. But if I did all 14, one at a time so it syncs, what happens after I change the 14th disk? Will the netapp still only use 320gb per disk, or will it realise it has a whole 1tb to play with?
