扩展VMware 虚拟机硬盘容量，不需要重装系统

janneyabc

　　目的：
扩展VMware虚拟机硬盘容量由15GB 至30GB
　　配置：
VMware : VMware Workstation 6.5.0
Host系统 : WinXP SP3
VMware安装系统 : Fedora 8
　　
Step.1 通过VMWare工具增加VMWare磁盘的容量
　　在命令行形式下执行， 安装所在盘的Program Files/VMware/VMware Workstation下有一个vmware-vdiskmanager.exe，就是它。
命令参数如下：
------------------------------------------------------------------
D:/Program Files/VMware/VMware Workstation>vmware-vdiskmanager.exe
VMware Virtual Disk Manager - build 118166.
Usage: vmware-vdiskmanager.exe OPTIONS <disk-name> | <mount-point>
Offline disk manipulation utility
Operations, only one may be specified at a time:
-c : create disk. Additional creation options must
be specified. Only local virtual disks can be
created.
-d : defragment the specified virtual disk. Only
local virtual disks may be defragmented.
-k : shrink the specified virtual disk. Only local
virtual disks may be shrunk.
-n <source-disk> : rename the specified virtual disk; need to
specify destination disk-name. Only local virtual
disks may be renamed.
-p : prepare the mounted virtual disk specified by
the drive-letter for shrinking.
-r <source-disk> : convert the specified disk; need to specify
destination disk-type. For local destination disks
the disk type must be specified.
-x <new-capacity> : expand the disk to the specified capacity. Only
local virtual disks may be expanded.
-R : check a sparse virtual disk for consistency and atte
mpt
to repair any errors.
　　Other Options:
-q : do not log messages
　　Additional options for create and convert:
-a <adapter> : (for use with -c only) adapter type
(ide, buslogic or lsilogic)
-s <size> : capacity of the virtual disk
-t <disk-type> : disk type id
　　Options for remote disks:
-h <hostname> : hostname of remote server
-u <username> : username for remote server
-f <filename> : file containing password
-P <port> : optional TCP port number (default: 902)
-S : specifies that the source disk is remote, by default
　　the remote options are assumed to refer to the
destination.
Disk types:
0 : single growable virtual disk
1 : growable virtual disk split in 2GB files
2 : preallocated virtual disk
3 : preallocated virtual disk split in 2GB files
4 : preallocated ESX-type virtual disk
5 : compressed disk optimized for streaming
　　The capacity can be specified in sectors, KB, MB or GB.
The acceptable ranges:
ide adapter : [1MB, 950.0GB]
scsi adapter: [1MB, 950.0GB]
ex 1: vmware-vdiskmanager.exe -c -s 850MB -a ide -t 0 myIdeDisk.vmdk
ex 2: vmware-vdiskmanager.exe -d myDisk.vmdk
ex 3: vmware-vdiskmanager.exe -r sourceDisk.vmdk -t 0 destinationDisk.vm
dk
ex 4: vmware-vdiskmanager.exe -x 36GB myDisk.vmdk
ex 5: vmware-vdiskmanager.exe -n sourceName.vmdk destinationName.vmdk
ex 6: vmware-vdiskmanager.exe -r sourceDisk.vmdk -t 4 -h esx-name.mycomp
any.com /
-u username -f passwordfile "[storage1]/path/to/targetDisk.vmdk"
ex 7: vmware-vdiskmanager.exe -k myDisk.vmdk
ex 8: vmware-vdiskmanager.exe -p <mount-point>
(A virtual disk first needs to be mounted at <mount-point>)
-----------------------------------------------------------------
其中的-x参数就是用来扩容的......
　　如这个：vmware-vdiskmanager.exe -x 36GB myDisk.vmdk
-----------------------------------------------------------------
　　我的执行过程：
进入DOS命令行，找到vmware-vdiskmanager.exe所在目录和需要WMWare虚拟磁盘Fedora.vmdk
　　D:/Program Files/VMware/VMware Workstation>vmware-vdiskmanager.exe -x 30GB "d:/dennis/work/VMWare/Fedora.vmdk"
出现提示，只需等待完成即可：
Grow: 100% done.
Disk expansion completed successfully.
　　总结：
1. 文件名应该用双引号括起来
2. MB, GB一定不要忘记B
　　需要强调的一点是，调整硬盘大小之后的效果，相当于增加了原来物理硬盘的柱面数目，因此，文件系统并不会自动增长。需要重新调整文件系统的大小。请看Step.2。
　　
Step.2 调整Fedora 8文件系统大小
进入Fedora 8系统终端，先添加一个磁盘分区
fdisk /dev/sda
n
p
4
t
8e
w
重启Fedora系统
　　然后把一个闲置的/dev/sda4分区挂上，并给VolGroup00/LogVol00扩容，正好原来/VolGroup00/LogVol00就放在一个lvm 的lv上
先把磁盘/dev/sdc加入到卷组MyLVM中
pvcreate /dev/sda4 #创建物理卷
　　对现有的VolGroup00 做扩展
vgextend VolGroup00 /dev/sda4 #扩展卷组
　　直接扩展/dev/VolGroup00/LogVol00 分区，不用umount，也不需要重启
lvextend -l +100%FREE /dev/VolGroup00/LogVol00 #扩展逻辑卷
lvresize -l +100%FREE /dev/VolGroup00/LogVol00 #resize 逻辑卷
resize2fs /dev/VolGroup00/LogVol00 #resize ext3文件系统
　　
我的执行过程：
[iyunv@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)
