创建和使用分区

    创建一个名为 /home/curtis/ansible/partition.yml 的 playbook：

        该palybook包含一个paly，该paly在balancers主机组的主机上运行：

            在设备vdb上创建单个主分区，编号为1，大小为1500MiB 

            使用ext4文件系统格式化该分区

            将文件系统永久挂载到/newpart 

            在设备vdd上创建单个主分区，编号为1，大小为1500MiB 

            使用ext4文件系统格式化该分区

            将文件系统永久挂载到/newpart1 

            如果无法创建请求的逻辑卷大小，应显示错误信息

            Could not create logical volume of that size

             ，并且应改为使用大小 800 MiB。

            如果设备 vdd 不存在，应显示错误信息

            Disk does not exist
