Unrecoverable FS errors

Unrecoverable FS errors

[V10lator]

Hi,

First off if this is the wrong mailing list please tell me, I just couldn't 
find any other for f2fs.

Around a year (maybe longer) ago my computer crashed, the only way was a 
hard reset which caused f2fs corruptions. Since then fsck.f2fs -f finds 
errors. These are always the same errors.

Today I noticed my package manager unlinking a death link but that failed, 
so I looked into the directory for myself:

ls /etc/ssl/certs/ | grep EBG_Elektronik
EBG_Elektronik_Sertifika_Hizmet_Sağlayıcısı.pem


so the file is there, let's look closer:

$ LANG=C ls -l /etc/ssl/certs/ | grep EBG_Elektronik
ls: Zugriff auf 
'/etc/ssl/certs/EBG_Elektronik_Sertifika_Hizmet_Sağlayıcısı.pem' nicht 
möglich: Datei oder Verzeichnis nicht gefunden
l????????? ? ?    ?         ?             ? 
EBG_Elektronik_Sertifika_Hizmet_Sağlayıcısı.pem


Doesn't look good. One more try:

$ LANG=C file 
/etc/ssl/certs/EBG_Elektronik_Sertifika_Hizmet_Sağlayıcısı.pem
/etc/ssl/certs/EBG_Elektronik_Sertifika_Hizmet_Sağlayıcısı.pem: cannot open 
`/etc/ssl/certs/EBG_Elektronik_Sertifika_Hizmet_Sağlayıcısı.pem' (No such 
file or directory)


Okay, so the file is clearly corrupted. Let's remove it:

# LANG=C LC_ALL=C rm 
/etc/ssl/certs/EBG_Elektronik_Sertifika_Hizmet_Sağlayıcısı.pem
rm: cannot remove 
'/etc/ssl/certs/EBG_Elektronik_Sertifika_Hizmet_Sa'$'\304\237''lay'$'\304\261''c'$'\304\261''s'$'\304\261''.pem': 
No such file or directory



Is there anything I can do to remove that file (or the directory entry as I 
think there is no file) ?

Thanks,
Thomas "V10lator" Rohloff

Which version of fsck.f2fs did you use?
I suspect the version may be too old. You can get the latest one from:

http://git.kernel.org/cgit/linux/kernel/git/jaegeuk/f2fs-tools.git/log/?h=dev-test

Hi,

I compiled and tried the version you linked, sadly it's still the same.

Thanks for your support

Oh, was there no reported error?
Then, which kernel version are you using?

Thanks,
