Linux使用fdisk进行磁盘分区

创建分区:
[root@localhost ~]# fdisk -l #查看磁盘的分区情况
[root@localhost ~]# fdisk /dev/sdb #给/dev/sdb分区
Command (m for help): m #获得帮助，查看具体可以使用那些命令
Command action
a toggle a bootable flag
b edit bsd disklabel
c toggle the dos compatibility flag
d delete a partition
l list known partition types
m print this menu
n add a new partition #新建分区
o create a new empty DOS partition table
p print the partition table #显示分割表
q quit without saving changes
s create a new empty Sun disklabel
t change a partition’s system id
u change display/entry units
v verify the partition table
w write table to disk and exit #保存退出
x extra functionality (experts only)
Command (m for help): n
Command action
e extended #扩展分区
p primary partition (1-4) #主分区
Partition number (1-4): 1 #主分区的编号
First cylinder (1-10443, default 1):
Using default value 1
Last cylinder, +cylinders or +size{K,M,G} (1-10443, default 10443): +10G #指定分区的大小
Command (m for help): p
