Swift实验
控制节点新添加一块20GB磁盘
新添磁盘分成两个区，并格式化
分区一：挂载到obs1目录
分区二：挂载到obs2目录
bash

Welcome to fdisk (util-linux 2.32.1).
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.
Created a new DOS disklabel with disk identifier 0xb5fb75bc.
Command (m for help): n
Partition type
p primary (0 primary, 0 extended, 4 free)
e extended (container for logical partitions)
Select (default p): p
Partition number (1-4, default 1): 1
