创建虚拟硬盘

1、关闭VM中正在运行的虚拟系统；

2、在虚拟系统名称上点右键－》Virtual Machine Settings；

3、在Hardware页点“Add”－》Add a hard disk－》Create a new virtual disk－》SCSI(recommended)－》分配空间大小－》OK；

4、可以看见Hardware中出现了一块新的硬盘Hard Disk 2。

一、对虚拟硬盘进行分区和格式化

1.查看目前系统上有几块硬盘

[root@cncmail data1]# fdisk -l

第一块硬盘信息

Disk /dev/sda: 36.4 GB, 36401479680 bytes

255 heads, 63 sectors/track, 4425 cylinders

Units = cylinders of 16065 * 512 = 8225280 bytes

Device Boot Start End Blocks Id System

/dev/sda1 * 1 255 2048256 83 Linux

/dev/sda2 256 1530 83 Linux

/dev/sda3 4296 4425 1044225 82 Linux swap

/dev/sda4 1531 4295 f Win95 Ext'd (LBA)

/dev/sda5 1531 2805 83 Linux

/dev/sda6 2806 4295 83 Linux

Partition table entries are not in disk order

第二块硬盘信息

Disk /dev/sdb: 36.7 GB, 36703918080 bytes ## 这里发现/dev/sdb，容量36.7G，切未被分区

255 heads, 63 sectors/track, 4462 cylinders

Units = cylinders of 16065 * 512 = 8225280 bytes

Disk /dev/sdc doesn't contain a valid partition table

第二块硬盘没有分区表

[root@linux root]# fdisk /dev/sdb

对第二块硬盘进行分区

The number of cylinders for this disk is set to 4462.

There is nothing wrong with that, but this is larger than 1024,

and could in certain setups cause problems with:

1) software that runs at boot time (e.g., old versions of LILO)

2) booting and partitioning software from other OSs

(e.g., DOS FDISK, OS/2 FDISK)

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

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
