Try mdadm --create --metadata=3D0.90 ... Of course it can only be specified while creating the array. The renaming is pretty ugly. You can force specific names by circumventing the kernel autodetection. Add the following kernel paramete= rs: raid=3Dnoautodetect md=3D0,/dev/sda1,/dev/sdb1 ... This assembles md0 with sda1 and sdb1. You can also try to keep autodetection on and only force the numbering for your raid partition.
