我安装了所有需要的mongodb模块，但是当我运行时：sudo service mongod start我收到错误代码。当我查看日志中的错误时，输出结果如下：

另外，我运行：sudo service mongod status，输出为mongod is stopped，所以我知道它没有运行。
在堆栈之后，看起来错误与空间不足有关，但我的服务器有15gb免费且我正在运行sudo，所以我知道这不是权限错误....我怎样才能分配更多空间。 ..或者更好的是，我应该分配更多的空间？
感谢任何帮助。

将smallfiles = true添加到“/etc/mongodb.conf”。
现在尝试启动该服务，我认为这应该解决问题!!
设置为true以修改MongoDB以使用较小的默认数据文件大小。具体来说，smallfiles减少了数据文件的初始大小，并将它们限制为512兆字节。 smallfiles设置还将每个日志文件的大小从1千兆字节减少到128兆字节。
