我按照【使用指南】里的【挂载外置设备支持】里的步骤弄好了U盘后读取是这样的
Filesystem Size Used Avail Use% Mounted on
/dev/root 6.7G 1.6G 4.8G 25% /
devtmpfs 494M 0 494M 0% /dev
tmpfs 494M 0 494M 0% /dev/shm
tmpfs 99M 1.9M 97M 2% /run
tmpfs 5.3M 0 5.3M 0% /run/lock
tmpfs 494M 0 494M 0% /sys/fs/cgroup
/dev/sda1 31G 47M 30G 1% /mnt/sda1
tmpfs 99M 0 99M 0% /run/user/0
然后我安装 Docker 程序后再安装青龙面板，再一查就是这样了
Filesystem Size Used Avail Use% Mounted on
/dev/root 6.7G 2.3G 4.2G 35% /
devtmpfs 494M 0 494M 0% /dev

我总感觉哪里不对。大佬们帮我看看呗！
