我们有一个dev数据库因this issue而被破坏。有没有办法从数据库中恢复内容？如果我重新编译mongod以便 nsToDatabaseSubstring 总是返回我需要的结果或者没有任何意义怎么办？我只有一个数据库。

UPD：在DigitalOcean上运行时文件已损坏，因此我不确定他们使用的虚拟化软件。我目前正在尝试使用VMWare 4.3.28和docker。 基本上谷歌搜索指向我this线程，所以我认为它已被损坏，因为 SERVER-15369 。 我们没有较旧的备份，因此我们必须修复数据库或重写所有需要花费大量时间的内容。不幸的是，就是这样。我知道备份数据的重要性，但它刚刚发生。
UPD 2：已修复 所以我能够恢复日期，我运行一个新的mongo实例，将我的db文件复制回数据文件夹。然后在mongo控制台内部我将数据保存在磁盘上并关闭数据库。在我再次运行之后，我能够看到并转储我的数据。
