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.
