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  vari-
	      ous 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.
