Mongodb always creates the mongodb.lock file when the server starts and drops it before mongodb is stopped.
mongodb 总是在服务器启动时创建 mongodb.lock 文件，并在 mongodb 停止之前删除它。
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.
删除 mongodb.lock 不会影响任何数据，只是意味着 mongodb 没有正确停止。因此，您删除此文件并使用 -repair 选项运行应该修复数据库是正确的。
