Bios Fake Raid undetected by GUI after reinstall of OMV

amdcursed · 26. Juli 2016

Hello, I have a Bios RAID5 that was working fine on my previous install. I had to do a fresh install due to other configuration problems I created. After reinstall, I can not get the RAID to be recognized. It is a RAID5 using three 4TB WD Reds.

You have to activate the RAID. Please search the forum or the web how to do that.

It looks like all my drives are marked as spares and that is causing the problem and I cant find anything that works to reactivate and unmark them as spares.

Edit:

Ok I got it working. But I have to run mdadm --run /dev/md127 after every reboot and cat /proc/mdstat shows that the raid is becoming md126

cat /proc/mdstat
