docker 拉取报错：failed to register layer

failed to register layer: devmapper: Thin Pool has 162988 free data blocks which is less than minimum required 163840 free data blocks. Create more free space in thin pool or use dm.min_free_space option to change behavior

1，首先测试docker 登录

docker login --username=admin 10.1.1.247 --password=Harbor12345

2，测试拉取镜像，然后到一半就报错了，然后查看磁盘，发现磁盘并未爆满，究其原因，docker空间不足，在使用一段时间后的docker空间会被写满，使用docker info打印Data Space Used: 107.4 GB，默认空间是107G
