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.
