So how would you accomplish the task of replacing sda and sdb with
larger disks in the least amount of effort?  Downtime is not a
problem, taking backups of the data is not a problem, booting off a
live cd is not a problem; the goal is to find the least
labour-intensive way to do this.

As I understand it -- and as I've proved before in this list, my understanding is fundamentally flawed :-) -- there is a way to do this.

Basically you have to force one disk to fail using the raid administration software. You then remove the disk, replace it with the bigger disk, and rebuild it from the first one. The partition sizes may need adjusting. Then you force the other disk to fail, and replace it with the larger one, and then rebuild it from the other large disk.

Hopefully someone can flesh this out for me, or you may now have a starting point for some googling.
