基本步驟：分區——格式化——掛載——寫入文件
1、首先用fdisk -l命令查看添加的硬盤名稱，可以看到sdb為新增的硬盤

It's strongly recommended to switch off the mode (command 'c') and change display units to sectors (command 'u').

分析：主要參數的解析
1. 輸入 m 顯示所有命令列示。
2. 輸入 p 顯示硬盤分割情形，打印分區表。
3. 輸入 a 設定硬盤啟動區。
4. 輸入 n 創建新的硬盤分割區。
4.1. 輸入 e 硬盤為[延伸]分割區(extend)。
4.2. 輸入 p 硬盤為[主要]分割區(primary)。
5. 輸入 t 改變硬盤分割區屬性?！ ?/p>
- t:分區系統id號
- L:82:linux swap
- 83:linux
- 86：NTFS window分區
6. 輸入 d 刪除硬盤分割區屬性。
7. 輸入 q 結束不存入硬盤分割區屬性。
8. 輸入 w 結束并寫入硬盤分割區屬性
3、輸入n創建新的硬盤分區——輸入p創建主分區——輸入1設置一個分區——回車——回車（默認全部空間）

4、輸入p查看分區情況——輸入w保存退出（一定要w保存不然無效）

5、mkfs命令格式化磁盤

[root@oracle ~]# mkfs.ext4 /dev/sdbmkfs.ext4: invalid fragment size - /dev/sdb |
6、mount命令掛載分區

7、添加到/etc/fstab文件下保存退出否則重啟后硬盤消失
