my root partition is raided, and is now running only on its single spare

You may try using the --run option.
I do following
1) start the array with the healthy partition
let's say md0 with sda1 sdb1
and sdb1 is faulty
mdadm -A /dev/md0 --add /dev/sda1 --run
I get: device /dev/md2 already active - cannot assemble it
2) add the faulty partition to the array for syncing
mdadm /dev/md0 --add /dev/sdb1
3) check /proc/mdstat
cat /proc/mdstat
you can also stop the array at any time
mdadm -S /dev/md0
well, I really can't - since it's my root volume
