Question: Why create mdadm also a md127, I found this now ?

Kernel is mapping /dev/md/Volume0 to /dev/md126. It's doing the same on my
system, although it's using md126. Not sure if that's controllable or not.
Maybe someone else can answer it.

No Problem, but i tell it to you, for me it is mystery. ;)
