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.


  1. Select the virtual machine in the inventory.
  2. Click the Summary tab and, under Resources, double-click the datastore for the virtual machine to open the Datastore Browser dialog box.
  3. Click the virtual machine folder to find the virtual disk file you want to convert. The file has the .vmdk extension.
  4. Right-click the virtual disk file and select Inflate.


The inflated virtual disk occupies the entire datastore space originally provisioned to it.
