Operational error occurred while fscking.

but there's no lost_name_1002b:6d757369630000:106e5 file on the partition.

Does anyone know how to repair my partition?

This is fsck bug.

Would you please pack the metadata by
debugfs.reiser4 -P /dev/xxx | gzip > meta.gz
and let me download the file meta.gz

Thanks,
Edward.

Than fsck has fixed pertition and i lost 1 level names in my
/home/<user> directory. I found its in lost+found and renamed.
I decided to update kernel to 33 zen. Later the kernel has suspend
again but without kernel errors. From live cd I ran fsck again but
there's no too many errors as the first time. After all rolled back to
31 kernel because the system was stable on it.

And now I have the problem with lost dir.

Thanks,
Danila Beketov

Hello.
I have downloaded your metadata.

I see this directory, but can not extract it so far.. It's old name
has been removed, but new one wasn't created for some reasons.

Eventually I have found that all link/unlink stuff in reiser4 is racy:
the process which creates a child takes an exclusive flag
REISER4_IMMUTABLE so that other concurrent processes
should wait on this flag. However, instead of waiting they return
reiser4-specific error number (-E_REPEAT) to the VFS...
Will be fixed.

I'll take a look why fsck don't want to put your poor directory to
lost+found. but it'll take some time (I have only weekends for
reiser4).

The oops below is specific to zen-kernels. Sometimes zen
folks try to fix reiser4 without success, so before sending oopses
to this mailing list please make sure that you use -mm kernels,
or reiser4 stuff against vanilla kernels from kernel.org.

Thank you.
Edward.

Re: reiser4: mv command lost folder.

[Danila Beketov]

Thanks for response!

In the lost folder was recoverable data, so I'll recreate the partition.
