If you created a virtual disk in the thin format, you can convert the thin disk to a virtual disk in thick provision format.

Before you begin

  • Make sure that the datastore where the virtual machine resides has enough space.

  • Make sure that the virtual disk is thin.

  • Remove snapshots.

  • Power off your virtual machine.

About this task

You use the datastore browser to inflate the virtual disk.

Procedure

  1. Navigate to the folder of the virtual disk you want to inflate.
    1. In the vSphere Web Client, browse to the virtual machine.
    2. Double-click the virtual machine to display its information.
    3. Click the Related Objects tab and click Datastores.

      The datastore that stores the virtual machine files is listed.

    4. Select the datastore and click the Navigate to the datastore file browser icon.

      The datastore browser displays contents of the datastore.

  2. Open the virtual machine folder and browse to the virtual disk file that you want to convert.

    The file has the .vmdk extension and is marked with the virtual disk (Virtual Disk icon.) icon.

  3. Right-click the virtual disk file and select Inflate.
    Note:

    The option might not be available if the virtual disk is thick or when the virtual machine is running.

Results

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