It looks like the superblocks didn't get updated together due to your
improper reboot. (Event counts don't match.)
I suggest you stop the array and reassemble with "--force", like so:
mdadm --stop /dev/md0
mdadm --assemble --force /dev/md0 /dev/sd[bcd]1
The "--force" option will instruct mdadm to ignore the event count mismatch.
You probably want to investigate why your array wasn't properly stopped
during shutdown.
HTH,
Phil
