SolrCloud never creates replicas automatically, unless perhaps you’re using the HDFS-only autoAddReplicas option. Start the new node using the same ZK, and then use the Collections API (https://cwiki.apache.org/confluence/display/solr/Collections+API) to ADDREPLICA.
The replicationFactor you specified at collection creation is pretty much ignored after creation.
