Is /boot a partition on top of the md device? If it is, you should make |
| 19 |
sure to use the --metadata=0.90 when creating the md devices. If it is a |
| 20 |
separate md device, this should not be necessary. |
| 21 |
|
| 22 |
If you run into issues concerning the renaming, you can try to specify |
| 23 |
the md devices explicitly with the kernel parameter 'raid=noautodetect |
| 24 |
md=0,/dev/sda1,/dev/sdb1' |
