Can't find out what's wrong?
I tried testdisk and can see all my files and directories.
There is a similar issue(#85), but that had fast_commit enabled

I had to cancel a running e2fsck, and now it doesn't give any errors, just Killed

for those having the same issue, just run e2fsck on beefier system with more ram
