      Description

      I have running mongod 3.2 with --dbpath on NFS.

      When I run mongod -f /etc/mongod.conf then mongod is running and accepting connections, but file `/var/lib/mongodb/data/mongod.lock` is empty.
      So mongod -f /etc/mongod.conf --shutdown is not working for me (getting error There doesn't seem to be a server running with dbpath: /var/lib/mongodb/data)

      How it is possible? I am trying to figure out how to reproduce it, but for now what could be reason of this odd behavior?

      Content of /etc/mongod.conf
