Answer 1

I had the same problem. Thanks to this question and previous answers, I decided:

• I checked all running mongod processes ps -ef | grep mongo. I had 1 mongo process and 2 mongod.
• I killed mongod with sudo sudo killall mongod
• and in the end I started with sudo sudo mongod --port 27017 --dbpath \srv\mongodb\rs0-0 --replSet rs0 --smallfiles --oplogSizeand it worked
