[quote="2Psycho"]When I try to open the drives via an live linux version it is also generating errors.
Could not stat device /dev/md/0 - No such file or directory
Could not stat device /dev/md/1 - No such file or directory
[/quote]Device names may be different, depending on the linux distribution and kernel version used. You will also have to assemble the arrays manually before the divices will appear (check /proc/mdstat).
[quote="2Psycho"]Further more I can see different names then expected for the raid arrays.
They are called md126 = 3TB and md127 = 1GB.
Within the /etc/mdadm/mdadm.conf
there are 2 MD1 references:
ARRAY /dev/md/1 metadata=1.2 UUID=xxxxx:xxxxxxx:xxxxxxx:xxxxxx name=unassigned-hostname:1
ARRAY /dev/md/1 metadata=1.2 UUID=yyyyyy:yyyyyy:yyyyyy:yyyyyyname=unassigned-hostname:1
Only the second is matching to the disks.
I tried to disable one line also this didn't worked.[/quote]Where do you get those names from (md126, md127)? And what do you mean by "is matching to the disks"?
The first parameter of the ARRAY line (device name) should be different (see my last screenshot) but you will need both lines for the system to boot.
Please also check the output of "mdadm --detail --scan" and "blkid".
