I managed to switch from a 2x200Gb RAID-0 to a 3x200Gb RAID-5 without reinstalling using raidreconf <http://unthought.net/raidreconf/> on my AMD64. I'm still amazed it work flawlessly, as latest raidreconf dates from 2001! Obviously I backed-up everything before, but I didn't need used it. Although I ran in a Amd64, I compiled raidreconf as a 32-bit application, since I was afraid it wasn't 64-bit clean. Then it's a matter of writing two raidtabs -- one describing the current raid setup, and another describing the desired setup -- and run raidreconf.
