mkraid - initializes/upgrades RAID device arrays
mkraid [--configfile] [--version] [--force] [--upgrade] [-cvfu] </dev/md?>+
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.
-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.
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.
