MongoDB provides two options for performing an initial sync:
Restart the mongod with an empty data directory and let MongoDB’s normal initial syncing feature restore the data. This is the more simple option but may take longer to replace the data.
See Procedures.
Restart the machine with a copy of a recent data directory from another member in the replica set. This procedure can replace the data more quickly but requires more manual steps.
See Sync by Copying Data Files from Another Member.
