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

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

Command (m for help): w

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!

Proceed anyway? (y,n) y
