MongoDB Replica Set Sync data by Copying Data Files from Another Member
The way you perform the resync isn't right. To perform resync of the secondary member (assuming it is already a member of the replica set), bring down (stop mongod process) the secondaray node, delete all the folders from the /data directory including journal and restart the node so it re-joins the replica set again

Once it re-joins the replica set, mongodb will automatically copy all the data files including local database to the secondary. You don't need to copy admin or local database manually as mongo will take care of it

Thank you!
