Thanks, I will try it.
it being "issuing "dmraid -an" should suffice then just run "mdadm
-As"."
However before I will, I would like to know if this is safe?
Is there a chance that I will lose all my data simply from this and
mounting, I ask since it is a new feature.

How do I load my existing raid arrays with mdadm?
first make sure they have not been claimed by dmraid.
issuing "dmraid -an" should suffice
then just run "mdadm -As".
looking at /proc/mdstat you should see a container device (or array
using windows driver terminology) and the actual
raid volume.
under /dev/md you should also find meaningful device names and device
file for the partitions contained in the volume.

please quote either above or below, it is a pain to read if you quote
in
the middle.
That said, you use the term 'device' above with two differemt meanings,
and i am not quite sure of what you intend.
please elaborate on "I have 3 raid devices"
- 3 hard disks in the container (array)
- a container with three volumes
then you probably mix partition and volume
xxxxxxxxxxxxx_System1 is the first partition on volume System of Array
xxxxxxxxxxxxx (unfortunately arrays dont have meaningful names)
xxxxxxxxxxxxx_System2 is the second partition ....
and so on
