The RAID1 seems to be failing according to that screenshot. That breaks the "Local File Systems" task and since quite a lot of things tend to depend on that, many things usually end up failing in an annoying cascade failure. It's also failing with a timeout instead of a strict error, which is odd.
Either way, I'd try commenting that line for /mnt/raid
in /etc/fstab for now and seeing if that makes the system boot. It's possible that journalctl -u dev-md0.service
or systemctl status dev-md0.service
might tell you more, but it's 50/50 if it'll be anything useful.
You're most likely booted, otherwise you might need a live USB. Hopefully, the system isn't in read-only mode. What I'd recommend doing is:
To make a copy once. Then,
nano /etc/fstab
to run nano, a basic CLI editor. You can use the arrow keys to navigate and type freely in it. The hints like^O
shown on the bottom mean ctrl+o.You'd use the arrow keys to go down to the line that probably says
/dev/md0 /mnt/raid morecrap
, put a#
in front of it, press ctrl+w then enter to save. If that worked, ctrl+x to exit and try areboot
again.Obviously can't promise this is "the" error preventing the system from booting, but it's generally a good idea to disable broken stuff like this to get the system working again, then fix it from there. Hopefully, this does the trick. Your RAID setup will not be activated on reboot after you do this but it's not going to permanently delete data or anything.
