VMware usage meter 2.3.2 -- Expand root partition

Hi at all,

I installed the version in the object, the hw requirement explained in the user guide says:

40GB or more disk storage,

but during the vApp's deploy the wizard can't permit a customization of the installation disk (15 GB). I have expanded the vmdk but obviously the / partition is always 15 GB,

could you help me? How can expand the partition?

Thank you, Francesco.
