DB在2019年-07-25T06:36:53.999+0900之后消失。下面是日志文件。我只是安装了一些ubuntu软件包，但是有一些问题，比如/boot文件夹磁盘空间问题，内核中断了，我试图用恢复模式启动，然后成功。但是在引导之后，我的mongodb数据看起来消失了--如果我访问我的网站，应该有一些文章，但我找不到这篇文章--也许它消失了。

我所做的是..。当访问ubuntu恢复模式时，在grup选择窗口中，我只选择了一次“清除”，它看起来就像excuting apt-get autoremove。当我意识到数据丢失后，我输入了一次mongod --repair。我只做了这两件事。啊，我三天前更新了ubutu版本。但那次数据库没有问题。

我的DB在哪？你能猜到吗？我没有备份，所以我很困惑。

启动mongodb时，我只输入了mongod，然后就找不到数据库了。

但是，当我像service mongod start一样启动mongodb时，我可以看到数据库。

我不知道两者之间有什么不同，但是第二条路我可以看到db。
