NAME
       debugfs.reiser4 - the program for debugging reiser4 filesystem.

SYNOPSIS
       debugfs.reiser4 [ options ] FILE

DESCRIPTION
       debugfs.reiser4 is reiser4 filesystem debug program. You can disscover
       the internal reiser4 filesystem structures by using it.

COMMON OPTIONS
       -V, --version
              prints program version.

       -?, -h, --help
              prints program help.

       -y, --yes
              assumes an answer 'yes' to all questions.

       -f, --force
              forces debugfs to use whole disk, not block device or mounted
              partition.

       -c, --cache N
              sets tree cache node number to passed value. This affects very
              much behavior of libreiser4. It affects speed, tree allocation,
              etc.

BROWSING OPTIONS
       -k, --cat
              browses passed file like standard cat and ls programs.

PRINT OPTIONS
       -t, --print-tree
              prints the internal tree.

       -b, --print-block N
              prints the block associated with the passed block number.

       -n, --print-nodes FILE
              prints all nodes that the passed file lies in.

       -i, --print-file
              prints all items that the passed file consists of.

       -s, --print-super
              prints the both super blocks: master super block and format
              specific one.

       -j, --print-journal
              prints the journal with not yet commited transactions (if any).

       -a, --print-alloc
              prints the block allocator data.

       -d, --print-oid
              prints the oid allocator data.

METADATA OPTIONS
       -P, --pack-metadata
              fetches filesystem metadata and writes them to the standard
              output.

       -U, --unpack-metadata
              reads filesystem metadata stream from the stdandard input and
              constructs a new filesystem based on the metadata.
              debugfs.reiser4 --pack-metadata <FS1> | debugfs.reiser4
              --unpack-metadata <FS2> and then debugfs.reiser4 --pack-metadata
              <FS2> produces a stream equivalent to the first one.

PLUGIN OPTIONS
       -p, --print-profile
              prints the plugin profile. This is the set of default plugins
              used for all parts of a filesystem -- format, nodes, files,
              directories, hashes, etc. If --override is specified, then
              prints modified plugins.

       -l, --print-plugins
              prints all plugins libreiser4 knows about.

       -o, --override TYPE=PLUGIN, ...
              overrides the default plugin of the type "TYPE" by the plugin
              "PLUGIN" in the plugin profile.

Temporary Options
       -C     converts to the new backup layout. Use this only if you created
              a reiser4 fs with some previous version of reiser4progs.

Examples:
       debugfs.reiser4 -o nodeptr=nodeptr41,hash=rupasov_hash /dev/hda2
