Hello.

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

Here's link to bzipped metadata:
http://tootiny.net/zq09qj

Sorry, but this file looks corrupted.
Could you please try again?

Also make sure that packed meta-data are
extracted correctly by the following way:

#touch meta_tmp
#bzcat meta.bz2 | debugfs.reiser4 -U meta_tmp


This kind of corruption might indicate bugs
in reiser4 kernel stuff. In what circumstances
did it happen (was it power loss, etc), and
what kernel did you use?

There was a hard reset with reiser4 partition mounted, because kernel was hung due to oops:

reiser4-for-2.6.35 is buggy, please consider upgrading to .36 or later..

Edward.

Kernel is 2.6.35 - vanilla, patched with corresponding release of Reiser4 (thus, reiser4 module isn't the latest).
