I was running my system (compiling the 4.12 kernel) when it halted an hour ago. The screen was entirely grey, the keyboard wouldn't respond. Music kept playing for about 1 minute. After waiting a little more, I had no choice but to do a hard reset. Now it won't boot.
My root partition is F2FS on top of LUKS. After typing the LUKS password, the following error message appears:
[f2fs_do_mount:] Can't find valid checkpoint
I booted the Arch Linux ISO image and did:
cryptsetup open /dev/sda3 csystem fsck.f2fs /dev/mapper/csystem
FSCK fails with the same message "Can't find valid checkpoint".
Tried fsck with
-f switches, still didn't work.
Am I hopelessly screwed?
