NAME
        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.
