As I thought, mdadm.conf says to expect 2 spares, but there is really only
one.  Just edit the file and the message will stop.

Yes, now it's all fine, thanks!

But mdadm --examine --scan --verbose still shows spares=2:

ARRAY /dev/md2 level=raid1 num-devices=2
UUID=7aa24776:9d6e8d24:54307b3d:1949437b
   spares=2
devices=/dev/sdc3,/dev/sdc,/dev/sdb3,/dev/sdb,/dev/sda3,/dev/sda

...although mdadm.conf was updated:

grep -A1 md2 /etc/mdadm/mdadm.conf
ARRAY /dev/md2 UUID=7aa24776:9d6e8d24:54307b3d:1949437b
   spares=1
