Stan will probably be angry with me but I did the following:

I found the recovery page in your wiki:
https://raid.wiki.kernel.org/index.php/RAID_Recovery

So I followed the process there.
This is what I did:

~$ mdadm --examine /dev/sd[abcd] > raid.status.md1

~$ mdadm --create --assume-clean -c 128 --level=5 --raid-devices=4 /dev/
md1 /dev/sda /dev/sdb /dev/sdc /dev/sdd

It was up and clean.

~$ mdadm --examine /dev/md[12] > raid.status.md0

~$ mdadm -C --assume-clean -n2 -l linear /dev/md0 /dev/md[12]

Now I could mount md0 and all my data is still there :-D

Thanks for this great wiki page!


Best regards
Ramon
