raidstop
raidstart(8) System Manager's Manual raidstart(8)NAME
raidstart, raidstop, - command set to manage md devices.
SYNOPSIS
raidstart [options] <raiddevice>*
raidstop [options] <raiddevice>*
DESCRIPTION
RAID devices are virtual devices created from two or more real block devices. This allows multiple disks to be combined into a single
filesystem, possibly with automated backup and recovery. Linux RAID devices are implemented through the md device driver.
If you're using the /proc filesystem, /proc/mdstat gives you informations about md devices status.
Currently, Linux supports linear md devices, RAID0 (striping), RAID1 (mirrroring), and RAID4 and RAID5. For information on the various lev-
els of RAID, check out:
http://ostenfeld.dk/~jakob/Software-RAID.HOWTO/
for new releases of the RAID driver check out:
ftp://ftp.fi.kernel.org/pub/linux/daemons/raid/alpha
Avaible commands are :
mkraid : configures (creates) md (RAID) devices in the kernel, banding multiple devices into one.
raidstart : activates (starts) an existing 'persistent' md device
raid0run : activates old nonpersistent RAID0/LINEAR md devices
raidstop : turns off an md device, and unconfigures (stops) it
By default, a systems RAID configuration is kept in /etc/raidtab, which can configure multiple RAID devices.
All of these tools work similiarly. If -a (or --all) is specified, the specified operation is performed on all of the RAID devices men-
tioned in the configuration file. Otherwise, one or more RAID devices must be specified on the command line. For example:
raid0run -a
Starts all of the 'old' RAID0 RAID devices specified in /etc/raidtab. If only /dev/md1 should be started, the following command should be
used instead:
raidstart /dev/md1
OPTIONS -a, --all
Apply the command to all of the configurations specified in the config file.
-c, --configfile filename
Use filename as the configuration file (/etc/raidtab is used by default).
-h, --help
Displays a short usage message, then exits.
-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.
