The parameter for specifying metadata versions is -e. Try |
| 27 |
mdadm --create --metadata=0.90 ... |
| 28 |
|
| 29 |
Of course it can only be specified while creating the array. |

The renaming is pretty ugly. You can force specific names by |
| 32 |
circumventing the kernel autodetection. Add the following kernel parameters: |
| 33 |
raid=noautodetect md=0,/dev/sda1,/dev/sdb1 ... |
| 34 |
|
| 35 |
This assembles md0 with sda1 and sdb1. You can also try to keep |
| 36 |
autodetection on and only force the numbering for your raid partition. |
| 37 |
|
| 38 |
Hope this helps, |
