The first time I was launching mongod with
mongod --config /shared/single.cfg
it works, and I could execute
However, I accidentally closed the windows cmd and when I reopened it and executed mongod, it did not connect anymore. I see this error:
vagrant@m312:~$ mongod --config /shared/single.cfg
about to fork child process, waiting until server is ready for connections.
forked process: 13983
ERROR: child process failed, exited with error number 100
