推荐答案

Mongodb总是在服务器启动时创建mongodb.lock文件，并在mongodb停止之前将其删除.

Mongodb always creates the mongodb.lock file when the server starts and drops it before mongodb is stopped.

删除mongodb.lock不会影响任何数据，仅表示mongodb没有正确停止.因此，删除该文件是正确的，并且使用-repair选项运行应该可以修复数据库.

Removing mongodb.lock does not affect any data it just means that mongodb was not stopped correctly. So, you are correct in removing this file and running with the -repair option should fix database.
