米文动力 AD10，添加新硬盘，系统迁移

大家好，欢迎来到IT知识分享网。

前要：买的米文动力工控机，系统内存太小，只有60g，开发不够，想着添加一个新硬盘，从新硬盘启动，以便反复刷机，反正测试，系统崩溃，找了很多资料，没成功，最后寻求米文技术支持解决。

1.把copy_rootfs.sh文件copy到设备中
2. chmod +x给脚本文件添加可执行权限
3. sudo mkfs -t ext4 /dev/xxx，格式化外部存储设备
4. ./copy_rootfs_3_in_1 /dev/xxx，xxx为外部存储设备
5. 把nvme_config.sh文件copy到设备中
6. chmod +x给脚本文件添加可执行权限
7. 执行sudo ./nvme_config.sh
8. 重启设备
9. 系统启动后后，执行df -h观察/目录是否在外部存储介质中
