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. ;)
It's the way IMSM works. You have md127 which is a "container",
essentially spanning all the discs concerned. That container holds one
or more RAID sets. You have md126 aka Volume0 as a RAID-1 set that fills
the container, but you could have more than one RAID set, e.g. you could
have a RAID-1 as md126 and a RAID-10 as md125.
Cheers,
John.
