If you created a virtual disk in the thin provision format, you can inflate it to its full size.
This procedure converts a thin disk to a virtual disk in thick provision format.
Launch the vSphere Client and log in to a vCenter Server system or an ESXi host.
- Select the virtual machine in the inventory.
- Click the Summary tab and, under Resources, double-click the datastore for the virtual machine to open the Datastore Browser dialog box.
- Click the virtual machine folder to find the virtual disk file you want to convert. The file has the .vmdk extension.
- Right-click the virtual disk file and select Inflate.
The inflated virtual disk occupies the entire datastore space originally provisioned to it.
