I was wondering if ksh supported arrays. I have a script that may work with several hosts. I'd like a means of knowing how many hosts I'm working with and an easy way to access them (as variables) in a loop. I'm assuming there's some kind of foreach in shell scripting. (1 Reply)

mkraid
mkraid(8) System Manager's Manual 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 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.
