It sounds like you stopped them before they completed joining. So you
should have nothing to worry about. If not, you will see them marked as DN
from other nodes in the cluster. If you did, they wouldn't have assumed the
token ranges and you shouldn't have any issues.

You can just copy the original data back (including system tables) and they
should assume their own ranges again, and then you can repair to fix any
missing replicas.
