Mdadm Live data conversion

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:
