Most of the documentation is a snapshot of the old Namesys site (archive.org, 2007-09-29).

There was also a Reiser4 Wiki (archive.org, 2007-07-06) once on pub.namesys.com.

Reiser4 development appears to have stalled and ReiserFS is deprecated and scheduled to be removed from mainline Linux in 2025.

NAME

mkfs.reiser4 - the program for creating reiser4 filesystems


SYNOPSIS

      mkfs.reiser4 [ options ] FILE1 FILE2 ... [ size[K|M|G] ]


DESCRIPTION

mkfs.reiser4 is reiser4 filesystem creation program. It is based on new libreiser4 library. Since libreiser4 is fully plugin-based, we have the potential to create not just reiser4 partitions, but any filesystem or database format, which is based on balanced trees.


COMMON OPTIONS

      -V, --version
             prints program version.
      -?, -h, --help
             prints program help.
      -y, --yes
             assumes an answer ’yes’ to all questions.
      -f, --force
             forces mkfs to use whole  disk,  not  block  device  or  mounted
             partition.


MKFS OPTIONS

      -b, --block-size N
             block size to be used (architecture page size by default)
      -L, --label LABEL
             volume label to be used
      -U, --uuid UUID
             universally unique identifier to be used
      -s, --lost-found
             forces mkfs to create lost+found directory.
      -d, --discard
             tells mkfs to discard given device before creating the filesystem (for solid state drives).


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


EXAMPLES

Assign short key plugin to "key" field in order to create filesystem with short keys policy:

             mkfs.reiser4 -yf -o key=key_short /dev/hda2
