Mdadm does not seem to support growing an array from level 1 to level 10.
I have two disks in RAID 1. I want to add two new disks and convert the array to a four disk RAID 10 array.
My current strategy:

Unless you're doing something that is very sensitive to speed issues I wouldn't worry about breaking things into small arrays or anything like that .

I'm building a new server (Small Business Server 2008), but I can't get the built-in RAID controller (AMD SB700) to work and have basically given up on it ever working with Server 2008. Fine.

Just simple disks.
When I read (quick overview, 5 sec.) the webpage on "RAID Reconstructor" right, you'd put these three disks into a computer with no RAID-controller attached.
