Mdadm Live data conversion

[Ovidio Borrero <ovidioborrero@gmail.com>]

Greetings,

I posted this on linux forums and was hoping to see what kind of 
responce i could get but they recommended emailing you guys. I apologize 
if i shouldnt be emailing you, but here's my question:

"Well i know in windows i can convert the live drive to a dynamic drive, 
and then create the raid in just a few simple steps, but how can i do 
this in linux? is it possible to convert the hard drive fs type to to 
fd? how can i make sda2 and sdb2 into md0? is this possible? heres my 
current fdisk output:
