新增磁盤和分區掛載我們先要了解fdisk的參數以及菜單的操作說明，下面是fdisk的參數說明：
?fdisk參數說明：
m ：顯示菜單和幫助信息
a ：活動分區標記/引導分區
d ：刪除分區
l ：顯示分區類型
n ：新建分區
p ：顯示分區信息
q ：退出不保存
t ：設置分區號
v ：進行分區檢查
w ：保存修改
x ：擴展應用，高級功能
1 ?查看磁盤分區：

2 ? 新增加硬盤分區
root@localhost ~]# fdisk /dev/sdb ? ? ? ? ? ?#(進到磁盤分區)
Device contains neither a valid DOS partition table, nor Sun, SGI or OSF disklabel
Building a new DOS disklabel with disk identifier 0xd4339e72.
Changes will remain in memory only, until you decide to write them.
After that, of course, the previous content won’t be recoverable.
Warning: invalid flag 0x0000 of partition table 4 will be corrected by w(rite)
WARNING: DOS-compatible mode is deprecated. It’s strongly recommended to
switch off the mode (command ‘c’) and change display units to

3 ?確認新增加磁盤分區
[root@localhost ~]# fdisk -l? ? ? （查看新增加磁盤分區結果）

5 ? 創建磁盤掛載節點
[root@localhost /]# mkdir data
6 ? 掛載磁盤
root@localhost /]# mount /dev/sdb1 data
7 ? 自動掛載
