Re: RAID installation at boot questions

Show all headers | View raw

I have more or less the same configuration. I am a no-systemd user
(yet?) so I cannot show you the full example.
You could verify:
- Is there a mdraid1x module  in your grub menu entry?
- If I not wrong you made your RAID by mdadm metadata version 1.2. I
think in this version metadata is located at first blocks, on the
other hand, version 1.0 places at the end blocks. Somewhere out there
I read blootable partitions could not use 1.2 metadata version. Thus,
for a bootable (and EFI, if exists) partition must be build in
metadata version 1.0. I did and it works. This you could solve your
problem.

To force a specific metadata version, I used:
mdadm --create --metadata=1.0 --verbose /dev/md2....
