What the howto and man mdadm don't tell

Checking the raid units

From man md:

echo check > /sys/block/md0/md/sync_action

check /proc/mdstat for status, and then set back to idle:

echo idle > /sys/block/md0/md/sync_action

Looking at your raid units

cat /proc/mdstat
mdadm --detail /dev/md0

(also shows what's going on when checking/resynching)

Hotswapping (scsi) disks

eject -s /dev/sda
