I want to start over the configurations of replica, is it possible? How to reset it?
In group people saying to remove the database content, but are there any work around?

If you want to keep the data, but start outside a replica set, just restart the mongod process without the --replSet and on a different port. That will give you a standalone mongod.
To be completely sure that the replica set configuration is gone from the instance, make sure that the local.system.replset collection is empty.
Once that is done, and you are happy with your standalone instance, you can then restart with a different --replSet argument and go through the replica set configuration process again:
http://www.mongodb.org/display/DOCS/Replica+Set+Configuration
The other option, as you mention, is to remove all the data files and start completely from scratch.
- 1//start server on different port than assigned but with same Db folder . connect via mongoi client to new port : use local db.system.replset.remove({"_id":"replset"}) //change replset in quotes to your name? db.system.replset.find() db.adminCommand({shutdown : 1}) //then restart on other porttgkprog– tgkprog2016-04-25 07:52:02 +00:00Commented Apr 25, 2016 at 7:52
You do not need to remove any database files in order to reset the configuration of your replica set.
To reset the configuration, make sure every node in your replica set is stopped. Then delete the "local" database for every node.
Once you are confident all nodes are not running and the local database are gone, start the mongod process again (of course using the --replSet flag). Then run rs.initiate().

/etc/mongod.confand comment outreplication: block service mongod restartmongo local --eval "db.dropDatabase()"service mongod stop- on mongo primary :
rs.add("this node") - edit
/etc/mongod.confand uncomment thereplication: block service mongod restart
Your node will get added to the existing replica set and will start syncing to the existing primary
