在docker中部署mongodb，报错directory-sync: fdatasync: Invalid argument.

Question

在docker中部署mongodb，数据文件持久化到mac（我本机）中，测试发现，只要将数据文件目录放到docker中就没问题，一旦将文件放到通过docker -v命令挂载过来的文件夹中就回爆出如下错误：

docker启动命令：

docker run -it -v /Usr/happyhour7/code/data:/data mongodb /bin/bash

我本机：mac，docker系统：ubuntu@14.04

你是直接在MacBook上运行Docker吧？关于Volume官方文档是这样说的:

File sharing

You can decide which directories on your Mac to share with containers.

Add a Directory - Click + and navigate to the directory you want to add.

Click Apply & Restart to make the directory available to containers using Docker’s bind mount (-v) feature.

意思是你需要先配置Docker，然后才能使用Volume
