I was looking for a simple slider to resize a disk in VMWare server recently and its not that simple if you want to resize a disk.
The solution is detailed in more detail here, but essentially you need run the following command on the host of the VMware machine:
vmware-vdiskmanager -x 30GB D:\VirtualMachines\virtualMachine1\virtualMachine1.vmdk
The above command essentially will resize the disk for virtualMachine1 to 30GB.
vmware-vdiskmanager is located in the installation directory as detailed here, but the following table gives common locations under 32 bit windows:
| Workstation | \Program Files\VMware\VMware Workstation |
| Player / ACE Instance | \Program Files\VMware\VMware Player |
| VMware Server | \Program Files\VMware\VMware Server |
| GSX | \Program Files\VMware\VMware GSX Server |
| Converter | \Program Files\VMware\VMware Converter |
| Capacity Planner | \Program Files\VMware\VMware Capacity Planner |
| Lab Manager | \Program Files\VMware\VMware Lab Manager Server |
| Stage Manager | \Program Files\VMware\VMware Stage Manager Server |
| Virtual Desktop Manager | \Program Files\VMware\VMware VDM\Server |
| Consolidated Backup | \Program Files\VMware\VMware Consolidated Backup Framework |
| VirtualCenter 2.5.x | \Program Files\VMware\Infrastructure\VirtualCenter Server |
| VirtualCenter 2.0.x | \Program Files\VMware\VMware VirtualCenter 2.0 |
| Virtual Infrastructure Client 2.5.x | \Program Files\VMware\VMware Virtual Infrastructure Client 2.0 |
| Virtual Infrastructure Client 2.0.x | \Program Files\VMware\Infrastructure\Virtual Infrastructure Client |
| Server Console (VMware Server) | \Program Files\VMware\VMware Server Console |
| Remote Console (GSX) | \Program Files\VMware\VMware Remote Console |
The procedure is not very detailed. I follow this detailed tutorial with diagram (http://www.partition-magic.org/vmware/vmware-resize-virtual-disk-vmdk-partition.html) to resize my virtual disk in VMware Server successfully.
