1.2：建立分区
fdisk /dev/sda
[root@xenserver zz]# fdisk /dev/sda
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.
Command (m for help): m
Command action
a toggle a bootable flag
b edit bsd disklabel
c toggle the dos compatibility flag
d delete a partition
g create a new empty GPT partition table
G create an IRIX (SGI) partition table
l list known partition types
m print this menu
n add a new partition
o create a new empty DOS partition table
p print the partition table
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
x extra functionality (experts only)
Command (m for help): n
Partition type:
p primary (0 primary, 0 extended, 4 free)
e extended
Select (default p):
Using default response p
Partition number (1-4, default 1):
First sector (2048-3907029167, default 2048):
Using default value 2048
Last sector, +sectors or +size{K,M,G} (2048-3907029167, default 3907029167):
Using default value 3907029167
Partition 1 of type Linux and of size 1.8 TiB is set

The partition table has been altered!
Calling ioctl() to re-read partition table.
Syncing disks.
1.3：格式化分区
mkfs.ext4 /dev/sda
[root@xenserver zz]# mkfs.ext4 /dev/sda
mke2fs 1.42.9 (28-Dec-2013)
/dev/sda is entire device, not just one partition!
