Before reboot:

# mdadm /dev/md0 --add /dev/sdc1
mdadm: Cannot open /dev/sdc1: Device or resource busy

After reboot (partition order has changed, /dev/sdc is now /dev/sda)

# mdadm /dev/md0 --add /dev/sda1
mdadm: /dev/sda1 reports being an active member for /dev/md0, but a --re-add fails.
mdadm: not performing --add as that would convert /dev/sda1 in to a spare.
mdadm: To make this a spare, use "mdadm --zero-superblock /dev/sda1" first.
