我最近在我的电脑上遇到了一些存储问题,因此我更改了mongo.conf文件以减小日志的大小.这些是我投入的线条.
mmapv1:
smallFiles: true
但是,每次当我尝试使用新的更改运行mongo时,我都会收到此错误(没有更改它可以正常工作).你能告诉我这是什么问题吗？

我会尝试删除该目录/data/db/diagnostic.data.
您还可以通过使用以下选项启动mongo来禁用诊断数据集合:
setParameter:
diagnosticDataCollectionEnabled: false
当 HD 已满 100% 时，MongoDb 失败后，我遇到了同样的问题。这是日志：

我kill-ed mongod 并清除了诊断文件夹的内容：
> rm -f /var/lib/mongo/diagnostic.data/*
mongo重启后日志显示：

和 mongo 没关系。
