This is a fresh install ov OMV 4.0.9 to USB flash drive. During the install I had internal HD removed. With the HD removed boot generated no errors. After installing the HD I get the following error during boot. It repeats the same error message about 30 - 40 times before finishing the boot:
mdadm: no arrays found in config file or automatically
As elsewhere suggested I modified /etc/mdadm/mdadm.conf to include:
# definitions of existing MD arrays
ARRAY <ignore> devices=/dev/sda
Then I did: omv-mkconf mdadm
This generated the follwing error:
mdadm /etc/mdadm/mdadm.conf defines no arrays
I rebooted and still get the same error message again. So I checked /etc/mdadm/mdadm.conf and noticed that the line I added was gone, so I added it again and rebooted; and I am still getting the same error message.
Any idea how get rid off this error at boot?
