Encountered a MongoDB warning after converting a replica set to stand alone server

Question

I encountered the following warning after converting a mongodb replica set to a stand alone server. I did rs.remove(\'host\') and removed the replSet arguments when starting

Answer 1

use local;
db.dropDatabase();
db.system.replset.remove ({});

Quit the mongo shell .. restart service just in case "service mongod restart"

mongo --host bind_ip --port bind_port
