Arch suddenly failed to load properly

Hi,
After an update two days ago, Arch suddenly failed to load properly.
This is the output. https://s2.loli.net/2023/03/24/a8QMSZJLBAt9v7R.jpg
I don't know what to do next. Can it be fixed? If not, is it possible to recover my data?
Thanks!

Re: Arch suddenly failed to load properly

fsck the filesystem and see what you come up with.

Here is the output. https://s2.loli.net/2023/03/25/eduKVTIohMWasSH.jpg
It seems not useful.
The command I used is

fsck.f2fs -a /dev/sdb2

.

https://man.archlinux.org/man/fsck.f2fs.8#f

Make a copy of the partition (dd/dd_rescue) first!

Unfortunately, the file system seems completely broken, and even after running

fsck -f /dev/sdb2

, it's still not working.

Re: Arch suddenly failed to load properly

Yan you mount the partition despite the errors?
Otherwise:
https://wiki.archlinux.org/title/File_r … d_PhotoRec

If this is just the system partition, you'll probably want to scrap it, start over and reconsider your choice of FS, https://wiki.archlinux.org/title/Talk:F2FS

I'm trying to use Photorec to recover data, but it seems unable to recover the original file names. Is there any tool that can recover the file names? Thanks

Re: Arch suddenly failed to load properly

Yes, the filesystem.
Photorec and testdisk scrape what looks like file fragments from the disk, but the paths related to those inodes is stored in the filesystem.

Lesson learned: Using obscure and fringe filesystems and having no backups is a recipe for disaster.
