题目：
1.给linux系统添加一块新硬盘
2.对该硬盘进行分区
3.格式化 xfs
4. 在/mnt中创建目录nvme1
5.将新增的分区 挂在到该目录
1）创建新硬盘
把虚拟机关机了，进入编辑页面
点击“添加”按钮
无脑下一步
这里推荐选这个，利于文件管理
搞完后点击“确定”即可
搞完后打开虚拟机看看有没有添加成功：使用lslbk命令（加上-p参数可以看到其决定路劲）
2）分区
#注意：gdisk命令针对GPT分区格式，若在MBR分区格式下进行添加分区，则所有数据会全部丢失，切记：一块新增的硬盘中fdisk与gdisk不能混用#找不到新增硬盘可以使用liblk命令查看（使用-p参数可以看到绝对路径）[root@HeHe dev]# fdisk /dev/nvme0n2Welcome to fdisk (util-linux 2.37.4).
Changes will remain in memory only, until you decide to write them.
Be careful before using the write command.Device does not contain a recognized partition table.
