Hi all,

I’m experiencing an issue with MongoDB after enabling replica set configuration.

Environment:
• MongoDB version: 8.0.6
• OS: Window server 2016
• Deployment: Single-node replica set (local development/testing)

Steps to reproduce the issue:

Start the MongoDB service
Create an admin and normal user using MongoShell
Stop the MongoDB service
Edited mongod.conf to add:
replication:
replSetName: rs0
Restart the MongoDB service and It will work fine for first time
Initiated the replica set using:
rs.initiate()
At this point, everything worked fine.
But after I restarted the entire system, MongoDB service fails to start with errors.

I have installed a lower version of 7.0.16 and enabled the replica set; it worked for me. I am not sure why the replica set is not worked for 8.0.6 version in VM machine
