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.

Examples:

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