扩展VMware 虚拟机硬盘容量，不需要重装系统心得
1.使用vmware自带vmware-vdiskmanager.exe进行扩容第一步。
首先，进入“运行”，cmd，进入vmware-vdiskmanager.exe所在目录（例如：我的是在C:/Program Files/VMware/VMware Workstation，则（1）c: (2)cd Program Files (3)cd VMware (4)cd VMware Workstation 最后进入C:/Program Files/VMware/VMware Workstation），执行vmware-vdiskmanager.exe -x 20GB "E:/Red Hat Enterprise Linux 5/Red Hat Enterprise Linux 5.vmdk"（其中20GB指扩容后的大小，E:/Red Hat Enterprise Linux 5/Red Hat Enterprise Linux 5.vmdk指要扩容的虚拟机的磁盘）
a. 异常情况：Failed to expand the disk 'E:/VM/SUSEServer.vmdk': One of the parameters supplied is invalid (0x100003e80).
原因：-x后的参数是扩大后的硬盘空间大小。如果空间大小小于或等于原有的硬盘空间大小，就会出现这个错误。
b. 异常情况：目录中有空格出现，要加上在路径上""
2 调整Fedora 8文件系统大小[转】 转载来自：http://blog.csdn.net/jjl_china/archive/2009/09/15/4550883.aspx
进入Fedora 8系统终端，先添加一个磁盘分区
fdisk /dev/sda
我的执行过程：
[root@localhost ~]# fdisk /dev/sda
The number of cylinders for this disk is set to 3916.
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)
