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 bad to idle:
echo idle > /sys/block/md0/md/sync_action
Looking at your raid units
cat /proc/mdstat
(also shows what's going on when checking/resynching)
Hotswapping (scsi) disks
eject -s /dev/sda
