修复n1的docker分区错误的挂载点，解决docker分区空间不足的问题

自动摘要

n1上的docker 空间严重不足，查看挂载点，明显发现这是两条错误的挂载 ，/dev/mmcblk2p4 没有挂载上去。而把 /dev/mmcblk2p2 （也就是openwrt系统目录）挂载上去了。需要把把旧文件转移并把 /dev/mmcblk2p4 挂载上/mnt/mmcblk2p4。

修复方法是:

mkdir /mnt/tmp

mount -t btrfs /dev/mmcblk2p4 /mnt/tmp

cp -r /mnt/mmcblk2p4/* /mnt/tmp

unmount /mnt/tmp

service dockerd stop

umount /mnt/mmcblk2p4

mount -t btrfs /dev/mmcblk2p4 /mnt/mmcblk2p4/docker

service dockerd start

挂载点正常

管理系统页的显示也OK

查看挂载点配置文件：cat /etc/config/fstab
