debugfs.reiser4 - the program for debugging reiser4
filesystem.
debugfs.reiser4 [ options ] FILE
debugfs.reiser4 is reiser4 filesystem debug program. You
can disscover the internal reiser4 filesystem structures by using it.
- -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.
- -k, --cat
- browses passed file like standard cat and ls programs.
- -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.
- -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.
