failed to register layer: ApplyLayer exit status 1 stdout: stderr: symlink usr/bin /bin: operation

OpenWrt系统上运行Docker时的问题，拉取docker镜像的时候，报错：failed to register layer: ApplyLayer exit status 1 stdout: stderr: symlink usr/bin /bin: operation

解决办法

1、把 /dev/sda1 格式化为 ext4

/etc/init.d/dockerd stop
umount /mnt/docker
mkfs.ext4 /dev/sda1
mount /dev/sda1 /mnt/docker

2、修改挂载目录

{
    
  "data-root"
