使用/usr/bin/dockerd启动测试发现是文件系统无法创建

1 WARN[2018-09-15T10:47:39.886191433+08:00] Usage of loopback devices is strongly discouraged for production use. Please use `--storage-opt dm.thinpooldev` or use `man dockerd` to refer to dm.thinpooldev section.  storage-driver=devicemapper

第三行日志可以找到mkfs的执行参数, 执行发现参数不正确
