Select Window > Virtual Machine Library. Select a virtual machine in the Virtual Machine Library window and click Settings. In the Settings window, click the hard disk you want to resize. Use the Disk size slider to set the new size.
Having thin provisioned disk is usually no longer a performance problem so it is a valid design choice even in production. A common issue with thin disks is that the size will grow when required, but never shrink. When you require the capacity only once you might want to get it back from the virtual machine.
First, click the “Defragment†button under Disk utilities to defragment the virtual machine's disk. When VMware finishes the defragmentation process, click the “Compact†button under Disk utilities. VMware will compact the underlying virtual hard disk (. vmdk) files to free up space.
How to Shrink a VirtualBox Virtual Machine and Free Up Disk Space
- Step One: Ensure You're Using a Dynamic Disk.
- Step Two: Write Zeros to the Disk in The Virtual Machine.
- Step Three: Find the VBoxManage Command.
- Step Four: Locate the Path to the Disk You Want To Compact.
- Step Five: Compact the Disk.

Using the vSphere Web Client:
- Navigate to vCenter > vCenter Server.
- Select vCenter Server currently having the issue and click the Manage tab.
- Click the Alarm Definitions tab.
- Click Datastore usage on disk alarm from the list and click Edit.
- Deselect the Enable this alarm option.
- Click Finish.
Datastores in VMware vSphere are storage containers for files. They could be located on a local server hard drive or across the network on a SAN. Datastores hide the specifics of each storage device and provide a uniform model for storing virtual machine files.
Navigate to Storage > Datastores and select the datastore you are trying to expand or increase. Right-click on the datastore and select Increase Capacity. Alternatively, select the Increase capacity button.
KnowledgeReclaim disk space from thin provisioned VMDK files in ESXi Server
- Step 1: Run below command to check information such as firmware revision, thin provisioning status, the VAAI filter and status for the datastore virtual machine is running:
- Step 2: "really" deleting space.
- Step 3: Run reclaim space in ESX.
VMware VMFS (Virtual Machine File System) is VMware, Inc.'s clustered file system used by the company's flagship server virtualization suite, vSphere. It was developed to store virtual machine disk images, including snapshots.
Checking disk space usage on the ESX/ESXi service console partitions
- Open a console to the ESX/ESXi host.
- Type df -h .
- Review the Use% for each of the listed items.
- When you have finished reviewing the output, type logout and press Enter to exit the system.
To shrink a virtual disk:
- Launch the control panel.
- Click the Shrink tab.
- Select the virtual disks you want to shrink, then click Prepare to Shrink.
- Click Yes when VMware Tools finishes wiping the selected disk partitions.
- Click OK to finish.
To shrink the virtual disk:
- Open the VMware Tools Control Panel / Toolbox: In Windows: Double-click the VMware Tools icon in the system tray, or click Start > Control Panel > VMware Tools. In Linux:
- Click the Shrink tab.
- Select the drive you want to shrink.
- Click Prepare to Shrink, then follow the onscreen instructions.
When implementing thin provisioning in VMware environment: Thin provisioned disks can grow to the full size specified at the time of virtual disk creation, but do not shrink. After allocating blocks, blocks cannot be un-allocated. By implementing thin provisioned disks, you are able to over-allocate storage.
VMDK (short for Virtual Machine Disk) is a file format that describes containers for virtual hard disk drives to be used in virtual machines like VMware Workstation or VirtualBox.
In short, the -flat.vmdk is the virtual disk for a vm, and should have a matching .vmdk, which is the descriptor file.
Select the VM that's running out of disk space. Right click the VM and select Edit Settings. On the Hardware tab select the virtual hard disk (e.g. Hard disk 1). On the right hand side, under Disk Provisioning increase the Provisioned Size then click OK.
Thick provision lazy zeroed is a provisioning format for a virtual machine (VM) disk that creates a virtual disk in a default thick format. Thick provision means all the space designated for the virtual disk files is reserved when the VM is created.
A thin-provisioned disk exhibits the same performance as a lazy-zeroed thick-provisioned disk. A thick-provisioned eager-zeroing disk will write data faster than a thin-provisioned disk. Because of overprovisioning, thin provisioning will cause problems when users approach their maximum storage capacity.
