For DDL's like dropDatabase() the writeConcern is "majority", you have to wait till it is propagated to secondary, i.e. 80'000 seconds which is 22.2 hours!
See db.dropDatabase() - Replica Set and Sharded Clusters.
Same applies for createIndex() by default. However there you can specify commitQuorum
