I think that's exactly what I'm doing right now with my test array. Basically I've 7 disks, all, but two, different in size. I created partitions, of equal size between disks, than I configured 4 RAID-6 devices (with 7, 6, 5, 4 partitions respectively) and put everything together with LVM. This works fine, it is possible to add HDs, or change the old ones with bigger new ones. One issue is that, with time, the larger HDs will have many partitions, this led to use GPT table (max 128 partitions) instead of DOS. Metadata needs to be 1.x, of course. The second point is the "annoyance" of creating those partitions on the new HDs and adding them to the proper md devices. Of course, nothing particularly difficult, nevertheless it would be nice to have everything integrated into the md driver and transparent to the user. Just an idea of improvement, nothing more. Side note: if anybody has suggestions on how to script the complete procedure of adding/replacing an HD in such configuration, I'll appreciate it a lot!
