Hello,
Apologies if this is not the correct mailing list, but it was the only one I
could find.
I just resized an f2fs partition to the remaining free space on the disk. This
seemed fine and resize.f2fs also seemed fine. However, the partition will no
longer mount, due to this message:
Aug 12 00:10:09 localhost vmunix: [22056.879920] F2FS-fs (sdb2): invalid
crc_offset: 0
Aug 12 00:10:09 localhost vmunix: [22056.881202] F2FS-fs (sdb2): Wrong
valid_user_blocks: 7163307, user_block_count: 5227520
Aug 12 00:10:09 localhost vmunix: [22056.881206] F2FS-fs (sdb2): Failed to get
valid F2FS checkpoint
Is there any way to fix this error?
I see this error reported before and supposedly fixed in current versions,
though I had use f2fs-tools v1.14. I tried using 1.15 and from git, but resize
reports nothing to do and fsck is successful. Here is that output:

I hope someone can help. It seems to just be a metadata issue? Is there a way
to manually fix the misreported block count to resolve this?
Thanks,
John
