Remove a drive from an active array
mdadm --manage /dev/md0 --fail /dev/sdX # set the drive as failed mdadm --manage /dev/md0 --remove /dev/sdX # remove the drive from the array
Add a drive to an active and degraded array
mdadm --manage /dev/md0 --add /dev/sdX # add the drive
Check array status
Both cat /proc/mdstat and mdadm --detail /dev/md0 have detailed output about configured arrays.
