1、在vmware中调整硬盘的大小
2、

启动Linux，键入df -h查看磁盘信息：

[plain]

[root@localhost ~]# df -h
Filesystem Size Used Avail Use% Mounted on
/dev/mapper/VolGroup00-LogVol00
29G 26G 2.3G 92% /
/dev/sda1 190M 13M 168M 7% /boot
tmpfs 506M 48K 506M 1% /dev/shm
gvfs-fuse-daemon 29G 26G 2.3G 92% /root/.gvfs

可以看到新增加的硬盘容量并没有体现在Linux中。使用fdisk -l查看分区表信息。我的信息是：

[plain]

[root@localhost ~]# fdisk -l
Disk /dev/sda: 42.9 GB, 42949672960 bytes
255 heads, 63 sectors/track, 5221 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes
Disk identifier: 0x000f1526
Device Boot Start End Blocks Id System
/dev/sda1 * 1 25 200781 83 Linux
/dev/sda2 26 3916 31254457+ 8e Linux LVM

注意Disk /Dev/sda有40多G空间（刚刚通过VMWare扩展的），但两个Device /dev/sda1和/dev/sda2加起来只有30多G，有10G空间没有被使用。

从调整分区表入手，调整分区表用fdisk。这个过程需要人机交互，我在需要输入的地方加注释来说明

[plain]

[root@localhost ~]# fdisk /dev/sda
The number of cylinders for this disk is set to 5221.
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): n //选择n表示新建分区
Command action

p primary partition (1-4)
e //选择e表示建立扩展分区
Partition number (1-4): 3 //选择3是因为1和2都被占了（/dev/dsa1和/dev/dsa2）
First cylinder (3917-5221, default 3917): //此分区起始柱面，直接按回车，使用默认值
Using default value 3917

可以看到新增了/dev/sda3扩展分区和/dev/sda5逻辑分区。如果是新增了一块硬盘，也可以直接新建一个主分区，步骤更简单些。

键入partprobe命令，这个命令用于在硬盘分区发生改变时，更新Linux内核中读取的硬盘分区表数据。

[plain]

[root@localhost ~]# partprobe

我们使用ext3格式化/dev/sda5这个新的分区

[plain]

[root@localhost ~]# mkfs -t ext3 /dev/sda5

3、挂载到文件系统
mkdir /software
mount -t ext3 /dev/sda5
