Re: [reiserfs-list] Re: Reiserfs corruption on 2.4.17-rc1!

[Asheesh Laroia]

This was exactly the problem I had.  It was solved by a getting a new
superblock via debugreiserfs, as patched by Yury Yu. Rupasov.  See the
thread at the beginning of the month, "Filesystem Corrupted".

It was resolved, again, by the patched debugreiserfs pre-release.  Run a
recent debugreiserfs and post the output.  It should give you the location
of a superblock backup.
