This is the output of blkid:

I have tried with the label: noname.
But still emergency mode.
Should I use the UUID?: UUID="2290f16f-03cf-847c-c2ff-285540a531dc"

/dev/md127: UUID="de77ee7e-abe0-4b3c-9667-ac91a6956390" TYPE="ext4"


That one appears to be your mdadm RAID device. Does it have a filesystem directly on that or is it used with LVM on top? If the filesystem is directly on /dev/md127 then that would be the correct uuid to use.

Hello TrevorH,

I took the UUID you have given and now I am happy and thank you very much.
This was excellent help.
It works fine again.

Once more thank you and have a nice evening.
Best regards
