对 mongodb 来说是全新的。我正在尝试在我的服务器上安装机车 CMS，这很酷，但我一直使用 SQL/MySQL，所以 mongo 对我来说是全新的。
我安装了所有需要的 mongodb 模块，但是当我运行时：sudo service mongod start我得到一个错误代码。当我在日志中查找错误时，输出如下：

另外，我运行：sudo service mongod status并且输出是mongod is stopped所以我知道它没有运行。
在堆栈之后，看起来该错误与空间不足有关，但我的服务器有 15gb 可用空间并且我正在运行 sudo，所以我知道这不是权限错误....如何分配更多空间...或更好的是，我应该为什么分配更多空间？
任何帮助表示赞赏。
