Problem with Serial ATA RAID (aka "fake RAID" or "BIOS RAID")

[Thomas Lange]

I would try to avoid RST, and just use software raid.
In your shell.log you have this line:

ERROR: Found Software RAID, but the mdadm package was not installed

You need the mdadm package installed, if you use software raid.

Try again with the package mdadm added, but I guess the fake raid is
the cause of your problem.
