一直都用虚拟机当服务器做事，装的东西越来越多，东西也越来越大，可用的磁盘空间越来越小。
以前只知道加一块硬盘的方式，增加容量，但不能为C盘扩展更大容量，C盘的可用的磁盘空间快捉襟见肘了，都有心重新弄一个虚拟机了。
突然有天，灵感来了，又搜索，有了解决方法： vmware-vdiskmanager.exe 在vmware workstation
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 attempt
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.vmdk
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.mycompany.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>)
照着ex4使用，但vmware没有自动把多出来的磁盘分给C盘，需要自己找工具把C盘和自由空间（执行命令后，扩展出来的）合并。
