    <title>Description</title>

    <para>raidfile-config creates a raidfile.conf file for Box Backup. This
    file holds information about the directories used to store backups in. Box
    Backup supports userland RAID, in a restricted RAID5 configuration, where
    3 and only 3 'drives' are supported. You can read more about RAID5 (and
    other RAID-levels) <ulink
    url="http://en.wikipedia.org/wiki/Redundant_array_of_independent_disks#RAID_5">here</ulink>.
    </para>

    <refsection>
      <title>Parameters</title>

      <para>The parameters are as follows:</para>

      <itemizedlist>
        <listitem>
          <para><literal>configdir</literal>: The directory path where
          configuration files are located. Usually this is
          <literal>/etc/box</literal>. <literal>raidfile.conf</literal> will
          be written in this directory.</para>
        </listitem>

        <listitem>
          <para><literal>blocksize</literal>: The block size used for file
          storage in the system, in bytes. Using a multple of the file system
          block size is a good strategy. Depending on the size of the files
          you will be backing up, this multiple varies. Of course it also
          depends on the native block size of your file system.</para>
        </listitem>

        <listitem>
          <para><literal>dir1</literal>: The first directory in the built-in
          RAID array.</para>
        </listitem>

        <listitem>
          <para><literal>dir2</literal>: The second directory in the built-in
          RAID array. If you are not using the built-in RAID functionality,
          this field should be ignored. You should not use the built-in RAID,
          when you have a hardware RAID solution, or if you're using another
          type of software RAID (like md on Linux).</para>
        </listitem>

        <listitem>
          <para><literal>dir3</literal>: The third directory in the built-in
          RAID array. The same notes that apply to <literal>dir2</literal>
          also apply to <literal>dir3</literal>.</para>
        </listitem>
      </itemizedlist>

      <para>Note that there are currently no way to add multiple disk sets to
      the raidfile.conf file using command line tools, etc. See
      raidfile.conf(5) for details on adding more disks</para>
