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

\[root@mail ~\]\# df -h /tmp

Filesystem            Size  Used Avail Use% Mounted on

/dev/sdb1            1004M  1.3M  952M   1% /tmp

7。自动挂载

修改/etc/fstab

增加一行

/dev/sdb1               /sdb1                   ext3    defaults        0 0

重起
