无法连接到Mongo db

我正在使用AWS和EC2和EBS。该系统确实工作并添加了安装的EBS驱动器。然后我将驱动器映射到/ data并在更改mongod.conf之前添加/ data/db以获取新的数据文件夹。现在mongo不会启动。当我从ubuntu命令行输入mongo时，我得到以下信息。无法连接到Mongo db

2015-04-14T10:49:21.292+0000 W NETWORK Failed to connect to

如果我使用的mongod尝试和得到的东西运行，它只是挂起如下：

我试图消除mongod.lock文件，它只是返回。日志似乎根本没有新条目。系统在更改conf之前确实有效，这是通过添加/数据和新的EBS的唯一改变。我有最新版本的mongo和ubuntu。
