I did the same, but as i explained it before, if i do :
mdadm --create /dev/md2 --level 1 --raid-devices 2 /dev/sda2 /dev/sdb2
I can use the device during the installation, but after reboot, the /dev/md2 is NOT mounted.
That because the "not metadata=0.90" arrays are decreasing numbered form /dev/md127 ... or named as /dev/md/name
That why i struggle with raid since my first post. I'm looking or the right way to do.
