mkraid(8)
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.
