+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."
