Mongo crash after 2 seconds of starting My mongod service crashes within 2-5 seconds of starting. I don't understand why.

Here are the systemctl logs:


  systemctl status mongod.service

So far I have:


checked permissions (everything looks good)
checked the service
tried deleting mongo.lock


mongod appears to start without any errors, but then fails after a couple of seconds.

Any ideas ?
Search for mongod.lock and remove it and restart the service.


Find out the Mongo data path cat /etc/mongod.conf | grep dbPath
Look for mongod.lock file in it.
If its there then delete the file and restart the server.
