Thanks Andreas, I have a problem
that for the file data I need the fs MetaData is corrupted. I hope
that because I am using same pre allocate logic all over my FS then I can get
the Maping from other clear state FS file And read the
data directly from the corrupted FS. Is that making
sense? Thanks, Yossi -----Original

I doing wrong? What you
are doing wrong is that you aren't using the debugfs "dump" command, which
will do what you are trying to do. Cheers, Andreas -- Andreas
