So it does have something to with the mapper devices. If I add "nodmraid" kernel parameter then mdadm raid works like it did before. I want searching config parameters for the kernel to see if I enabled DMRAID somehow but didn't find any. Why is the new disk/updated programs automatically starting dmraid? could it be udev rules .. I don't really understand them .. but dmraid is an option for non intel type raid, so what happens is dmraid is tried first for all but the intel items, then mdadm is used. But this is not coming from my call of dmraid, it's coming from someplace automatic ??
