1。增加前先关闭VM，然后编辑VM属性，增加一个vritual disk（scsi），其实是增加一个虚拟磁盘文件。

hard disk2就是我新增加的

?

2。查看目前的磁盘结构

[root@mail ~]# fdisk -l

Disk /dev/sda: 10.7 GB, 10737418240 bytes
255 heads, 63 sectors/track, 1305 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes

?? Device Boot????? Start???????? End????? Blocks?? Id? System
/dev/sda1?? *?????????? 1????????? 13????? 104391?? 83? Linux
/dev/sda2????????????? 14???????? 905???? 7164990?? 83? Linux
/dev/sda3???????????? 906??????? 1032???? 1020127+? 83? Linux
/dev/sda4??????????? 1033??????? 1305???? 2192872+?? 5? Extended
/dev/sda5??????????? 1033??????? 1159???? 1020096?? 82? Linux swap / Solaris
/dev/sda6??????????? 1160??????? 1305???? 1172713+? 83? Linux

Disk /dev/sdb: 1073 MB, 1073741824 bytes
255 heads, 63 sectors/track, 130 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes

Disk /dev/sdb doesn't contain a valid partition table
//说明磁盘/dev/sdb还没有被系统识别

?

3。分区

[root@mail ~]# fdisk /dev/sbd

Command (m for help): n? //输入m获得帮助信息，n创建分区
Command action
?? e?? extended
?? p?? primary partition (1-4)
p //创建主分区
Partition number (1-4): 1 //指定分区的起始柱面
First cylinder (1-130, default 1):
Using default value 1
Last cylinder or +size or +sizeM or +sizeK (1-130, default 130):? //设置分区容量，直接回车表示全部
Using default value 130

Command (m for help): t //改变一个分区的系统ID
Selected partition 1
Hex code (type L to list codes): L //查看文件类型对应的Hex

?85? Linux extended //linux? ext3的hex是85

Hex code (type L to list codes): 85
You cannot change a partition into an extended one or vice versa
Delete it first.

Command (m for help): p //列出当前硬盘的分区

Disk /dev/sdb: 1073 MB, 1073741824 bytes
255 heads, 63 sectors/track, 130 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes

?? Device Boot????? Start???????? End????? Blocks?? Id? System
/dev/sdb1?????????????? 1???????? 130???? 1044193+? 83? Linux

Command (m for help): w? //保存
The partition table has been altered!

Calling ioctl() to re-read partition table.
Syncing disks.

4。查看现在的分区

[root@mail ~]# fdisk -l

Disk /dev/sda: 10.7 GB, 10737418240 bytes
255 heads, 63 sectors/track, 1305 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes

?? Device Boot????? Start???????? End????? Blocks?? Id? System
/dev/sda1?? *?????????? 1????????? 13????? 104391?? 83? Linux
/dev/sda2????????????? 14???????? 905???? 7164990?? 83? Linux
/dev/sda3???????????? 906??????? 1032???? 1020127+? 83? Linux
/dev/sda4??????????? 1033??????? 1305???? 2192872+?? 5? Extended
/dev/sda5??????????? 1033??????? 1159???? 1020096?? 82? Linux swap / Solaris
/dev/sda6??????????? 1160??????? 1305???? 1172713+? 83? Linux

Disk /dev/sdb: 1073 MB, 1073741824 bytes
255 heads, 63 sectors/track, 130 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes

?? Device Boot????? Start???????? End????? Blocks?? Id? System
/dev/sdb1?????????????? 1???????? 130???? 1044193+? 83? Linux

5。格式化分区

[root@mail ~]# mkfs.ext3 /dev/sdb1? //格式化成ext3格式

6。挂载分区

[root@mail ~]# mount /dev/sdb1 /tmp
[root@mail
