Usage: $PROGNAME [options] [arrays]
|
||||
|
||||
Valid options are:
|
||||
-a|--all check all assembled arrays (ignores arrays in command line).
|
||||
-s|--status print redundancy check status of devices.
|
||||
-x|--cancel queue a request to cancel a running redundancy check.
|
||||
-r|--repair repair instead of check
|
||||
-i|--idle perform check in a lowest scheduling class (idle)
|
||||
-l|--slow perform check in a lower-than-standard scheduling class
|
||||
-f|--fast perform check in higher-than-standard scheduling class
|
||||
--realtime perform check in real-time scheduling class (DANGEROUS!)
|
||||
-c|--cron honour AUTOCHECK setting in /etc/default/mdadm.
|
||||
-q|--quiet suppress informational messages
|
||||
(use twice to suppress error messages too).
|
||||
-h|--help show this output.
|
||||
-V|--version show version information.
|
||||
|
||||
Examples:
|
||||
$PROGNAME --all --idle
|
||||
$PROGNAME --quiet /dev/md[123]
|
||||
$PROGNAME -sa
|
||||
$PROGNAME -x --all
|
||||
|
||||
Devices can be specified in almost any format. The following are equivalent:
|
||||
/dev/md0, md0, /dev/md/0, /sys/block/md0
|
||||
|
||||
You can also control the status of a check/repair with /proc/mdstat file."
