# 使用 fdisk 磁盘管理命令
[root@FXQ-YWYY-57-81 ~]# fdisk /dev/vda
Welcome to fdisk (util-linux 2.35.2).
Changes will remain in memory only, until you decide to write them.
Be careful before using the write command.
Command (m for help): p
Disk /dev/vda: 50 GiB, 53687091200 bytes, 104857600 sectors
Units: sectors of 1 * 512 = 512 bytes
Sector size (logical/physical): 512 bytes / 512 bytes
I/O size (minimum/optimal): 512 bytes / 512 bytes
Disklabel type: gpt
Disk identifier: 55A9D713-559A-436B-BA30-299A54040073

d delete a partition # 删除
F list free unpartitioned space
l list known partition types
n add a new partition # 新增
p print the partition table
t change a partition type # 更改分区类型
v verify the partition table
i print information about a partition
Misc
m print this menu
x extra functionality (experts only)
Script
I load disk layout from sfdisk script file
O dump disk layout to sfdisk script file
Save & Exit
w write table to disk and exit
q quit without saving changes
Create a new label
g create a new empty GPT partition table
G create a new empty SGI (IRIX) partition table
o create a new empty DOS partition table
s create a new empty Sun partition table
# 新增 n ，内存取默认就行
Command (m for help): n
Partition number (4-128, default 4): 4
First sector (70436864-104857566, default 70436864):
Last sector, +/-sectors or +/-size{K,M,G,T,P} (70436864-104857566, default 104857566):
Created a new partition 4 of type 'Linux filesystem' and of size 16.4 GiB.
Partition #4 contains a swap signature.
# 默认 y
Do you want to remove the signature? [Y]es/[N]o: y
The signature will be removed by a write command.
# 保存
Command (m for help): w
The partition table has been altered.
Syncing disks.
