It looks like a device is completely missing? blkid > blkid.txt Then for each md device UUID pair (the md UUID will show up twice in blkid for each of the three arrays): mdadm -E <dev1> <dev2> >> mdXraidstats.txt Where X=the md device from mdstat. That way you get the superblock from each device making up each array into an array specific text file. They can go all in one file, but it's easier to keep things separate. journalctl -b -l -o short-monotonic > journal.txt /etc/mdadm/mdadm.conf Post those files somewhere and the URL here. The journal should say why it wasn't assembled. But the main thing is you should get copies of all device superblocks before you do anything else, especially reading around the internet where often people get the idea that they need to use -C to recreate an array which obliterates the old metadata and almost invariably kills their data.
