I believe the conditional restart condition of the mongod init script (/etc/init.d/mongod) has a typo for the filename being checked for the conditional restart condition. It is using /var/lock/subsys/mongodb to see if mongo is running and I think it should be using /var/lock/subsys/mongod instead

63 condrestart)
64 [ -f /var/lock/subsys/mongodb ] && restart || :
65 ;;

The start and stop conditions use mongod instead of mongodb

27 start()
28

{ 29 echo -n $"Starting mongod: " 30 daemon --user "$MONGO_USER" $mongod $OPTIONS 31 RETVAL=$? 32 echo 33 [ $RETVAL -eq 0 ] && touch /var/lock/subsys/mongod 34 }

36 stop()
37

{ 38 echo -n $"Stopping mongod: " 39 killproc -p /var/lib/mongo/mongod.lock -t30 -TERM /usr/bin/mongod 40 RETVAL=$? 41 echo 42 [ $RETVAL -eq 0 ] && rm -f /var/lock/subsys/mongod 43 }
