Ahmed,
in my set up controller is a node too. if your controller is capable of
doing that, there is no harm, its ok.
there is no need to put any service together with each other. so you may or
not put nova-volume in compute nodes. you can dedicate a whole node to
serve only nova-volume. depends on your set up. I think now with Cinder,
volume things will be more clear!

I had an ideia once that was using controller node as virtual machine. I
don't know if anyone ever tried this out, if yes I would like to know!
