Hello,

I made a typo in the URL earlier. It should be https://arter97.com/.f2fs-20250406/fsck.log . Could you try it, please?

Thanks.

Hello everyone,

I am having trouble with F2FS. Specifically, I believe metadata got corrupted when I resized it. I have a 512 GB drive. My F2FS partition was approximately located on 369-497 GB (128 GB size). Using GParted, I resized it to 0.5-497 GB. While the partition resizing went through successfully, filesystem resizing initially failed with "Mount unclean image to replay log". I have done that and retried
resizing.

Afterwards, however, fsck started giving out a lot of errors, at one point it asked if I wished to restore lost data, which I agreed to. Logs specified a lot of my files (which I could tell by filenames) and mid-way through the process, it segfaulted. Now, when I run fsck, no files are asked to be restored, and it completes successfully. However, when I attempt to mount it, I get an error
saying "Structure needs cleaning".

Could someone help me restore my metadata (at least, long enough to extract my files)? Thanks.

Hello,

Could you please upload fsck.log in bugzilla.kernel.org, or somewhere else?
I can not download it from above link address, sorry.

Thanks,
