1、关闭虚拟机，增加2张磁盘，模拟新增2块物理硬盘
根据需求修改磁盘大小
添加完成后如图所示
2、启动服务器，以root登录
3、查看磁盘信息
[root@localhost /]# fdisk -l

[root@localhost /]# fdisk /dev/sdb

Changes will remain in memory only, until you decide to write them.
Be careful before using the write command.

a toggle a bootable flag
b edit bsd disklabel
c toggle the dos compatibility flag
d delete a partition
g create a new empty GPT partition table
G create an IRIX (SGI) partition table

m print this menu
n add a new partition #增加新分区
o create a new empty DOS partition table
p print the partition table
q quit without saving changes

mkdir /data1/
mkdir /data2/[root@localhost /]# mount /dev/sdb1 /data1/
[root@localhost /]# mount /dev/sdc1 /data2/10、查看硬盘大小及挂载分区
