I have setup my primary server for replication and then when I stop and restart mongod it just fails.

Here is the error

[mongoadmin@europa ~]$ sudo service mongod start

Starting mongod (via systemctl): Job for mongod.service failed because the control process exited with error code. See "systemctl status mongod.service" and "journalctl -xe" for details.
