The parameter for specifying metadata versions is -e. Try mdadm --create --metadata=0.90 ... 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 parameters: raid=noautodetect md=0,/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. Hope this helps, Florian Philipp
