Welcome to fdisk (util-linux 2.23.2).

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

Building a new DOS disklabel with disk identifier 0xcda7f5f7.

Command (m for help): 
n

Partition type:
回車

p   primary (0 primary, 0 extended, 4 free)

e   extended

Select (default p):
 
p

Partition number (1-4, default 1): 
預設是1.可以輸入1 或者直接回車

First sector (2048-1048575999, default 2048): 
磁碟開始位置，可以輸入，可以直接回車

Using default value 2048

Last sector, +sectors or +size{K,M,G} (2048-1048575999, default 1048575999): 
可以輸入500G 或者回車

Using default value 1048575999

Partition 1 of type Linux and of size 500 GiB is set

Command (m for help): t

Selected partition 1

第二步：進行格式化

[root@zjy-dbana /]# mkfs.ext4 /dev/vdd1

格式化方式二：mkfs.xfs -f /dev/vdb1

第三步：掛載

準備掛載資料夾 backup

建立資料夾

[root@zjy-dbana /]# mkdir -p /backup/

檔案掛載

[root@zjy-dbana /]# mount /dev/vdd1 /backup

永久生效

[root@zjy-dbana /]# cat /etc/mtab  -- 檢視到最後一條複製下來
