I started the lesson Chapter 2: Tooling Overview: $indexStats, Part 1 and used the following mlaunch command as the video showed.
mlaunch init --replicaset --name m312RS -wiredTigerCacheSizeGB 0.5 --dir /data/m312RS --port 30000 --host localhost --oplogSize 10
But after connecting, I realized that the environment was empty. My database m312 was not there.
Then I exit and tried some ways to back to mongo I was using before and I couldn’t.
Now, even trying to reconnect using the same mlaunch command, I cannot back to mongo
This is the error I am facing.
What should I do in this case?
