ok, I'll figure this out :)

thanks, this is great news for me. For real use I will need to
repartition my hard drive - to create another partition for that.

But just for testing - will it work if mdadm will use LVM partition,
which is already on top of mdadm raid ?

Or maybe just use some huge file as a loopback device? 

Which testing method is better?
