1、基本存储配置
1） 添加一块10G大小的磁盘，将该磁盘分为两个主分区，大小为1G、2G。将剩余的空间全部划分为扩展分区。划分一个逻辑分区，大小为3G。（主分区文件系统类型为ext4，逻辑分区文件系统类型为xfs）
进入电源选项，选择打开电源时进入固件来选择硬盘的加载顺序。
调整磁盘顺序
查看磁盘情况
[root@server ~]# lsblk

格式化并更改分区的文件系统
[root@server ~]# mkfs -t xfs /dev/sda5

2） 将三个分区分别挂载到/dir1、/dir2、/dir3。
[root@server ~]# mount /dev/sda1 /dir1
[root@server ~]# mount /dev/sda2 /dir2
[root@server ~]# mount /dev/sda3 /dir3
[root@server ~]# df -h
Filesystem Size Used Avail Use% Mounted on
devtmpfs 364M 0 364M 0% /dev

/dev/sda2 2.0G 6M 1.8G 1% /dir2
/dev/sda3 3.0G 54M 3.0G 2% /dir3
3） 在第一个主分区中创建一个文件为file1，内容为this is partition1。在第二个分区中创建一个文
件为file2，内容为this is partition2。在第三个分区中创建一个文件为file3，内容为this is
partition3。
[root@server ~]# vim /dir1/file1
[root@server ~]# vim /dir2/file2
[root@server ~]# vim /dir3/file3
[root@server ~]# cat /dir1/file1 /dir2/file2 /dir3/file3
this is partition1
this is partition2
this is partition3
