      mkraid - initializes/upgrades RAID device arrays

SYNOPSIS

      mkraid   [--configfile]  [--version]  [--force]             [--upgrade]
      [-cvfu] </dev/md?>+


DESCRIPTION

      mkraid sets up a set of block devices into a  single  RAID  array.   It
      looks  in  its  configuration  file for the md devices mentioned on the
      command line, and initializes those arrays.  mkraid works for all types
      of RAID arrays (RAID1, RAID4, RAID5, LINEAR and RAID0).
 
      Note  that  initializing  RAID  devices destroys all of the data on the
      consituent devices.

OPTIONS

      -c, --configfile filename
             Use filename as the configuration file (/etc/raidtab is used  by
             default).
 
      -f, --force
             Initialize  the  consituent devices, even if they appear to have
             data on them already.
 
      -h, --help
             Displays a short usage message, then exits.
 
      -o, --upgrade
             This option upgrades older arrays to the current  kernel's  RAID
             version,  without  destroying data. Although the utility detects
             various  pitfalls  like  mixed   up   disks   and   inconsistent
             superblocks, this option should be used with care.
 
      -V, --version
             Displays a short version message, then exits.

NOTES

      The  raidtools  are  derived  from the md-tools and raidtools packages,
      which were originally written by Marc Zyngier, Miguel  de  Icaza,  Gadi
      Oxman, Bradley Ward Allen, and Ingo Molnar.

BUGS

      Probably many.
