Installing OMV 4 on a Intel motherboard Raid aka Fake RAID

Hi,

I am in the process of setting up a new backup server. Before that I used OMV 3 installed on a USB disk and I used software RAID but this time I want to install the system on the RAID disk directly, without using a USB stick. I have configured a RAID 0 on 2 disks using the BIOS utility.

I followed the debian instruction to install the OS on a RAID so I tried to start the installer with the kernel option : dmraid=true and I also tried mdadm=true.

The setup fail because it can't detect the RAID and write on it.

If I start a rescue shell I can see my raid :

$ cat /proc/mdstat
Personalities :
md127 : inactive sda[1](S) sdb[0](S)
6306 blocks super external:imsm

$ mdadm --detail --scan
ARRAY /dev/md127 metadata=imsm UUID=...

So my question is how can I use this RAID to install the system on it ? The only solution I'm thinking now is to install a regular debian and then OVM package on it.

Thank you for you answers.

Yes I am using the OMV disk. The type of RAID isn't important, I just want to be able to install OMV on a RAID directly. I will try the debian first method.
