How To Expand An Exisiting Virtual Disk
Important information before you begin
- All snapshots have been removed.
- The virtual machine is powered off.
Note: If you have multiple .vmdk files with the same base name, use the file that does not include -flat or -s0 in its file name.
You may need to:
- Locate the full path to a hosted (non-ESX host) virtual machine’s virtual disk (.vmdk ) file. For more information, see Locating a hosted virtual machine’s files (1003880).
Locate the full path to an ESX host’s virtual machine’s virtual disk (.vmdk ) files. For more information, see Verifying that ESX virtual machine storage is accessible (1003751).
Workstation / Player 3.x / ACE Manager / Server / GSX
To increase the virtual disk from the command line:
- Open a command prompt. For more information, see Opening a command or shell prompt (1003892).
- Navigate to the product’s installation directory. For more information, see Locating a VMware product’s installation directory (1003897).
Type vmware-vdiskmanager -x 100Gb vm.vmdk and press Enter.
Note: Replace 100Gb with the actual size of virtual disk that you want. You can also specify Kb and Mb.
- Select the virtual machine from the Inventory.
- Click Edit Virtual Machine Settings.
- Click Hard Disk.
- Click Utilities > Expand, enter the new size, then click Expand.
- Follow the steps in Increasing the size of a disk partition (1004071) so the guest operating system is aware of the change in disk size.
VMware Player 2.x / ACE Instance
If you are using an ACE Instance, the virtual disk size must be changed from the ACE Manager, then repackaged and redeployed.
If you are using VMware Player’s 2.x, upgrade to VMware Player 3. This is a free download, available from our Download Center.
ESX / VI Client / vSphere
This error may occur because of a number of different issues:
Failed to open the disk ‘vm.vmdk’ : A file was not found (0x1900000004)
Open VMware Infrastructure (VI) Client and connect to VirtualCenter or the ESX host.
Right-click the virtual machine.
Click Edit Settings.
Select Virtual Disk.
Increase the size of the disk.
For earlier versions of ESX, you must use the Console. For more information, see Adding Space to an ESX Server Virtual Disk (994).
For further details on Virtual Disk Configuration, you can reference the vSphere Virtual Machine Administration Guide.
Open Lab Manager.
Consolidate and then deploy the template to be resized. For instructions, see the Lab Manager User’s Guide.
Connect to the ESX host where the template was deployed using VI Client.
Perform the disk resize according to the ESX section above.
