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.
