Resize a Hard Disk for a Virtual Machine

Our Virtual Machines are provisioned using Vagrant from a Linux base box to run using VirutalBox. If the Hard Disk space runs out and you cannot remove files to free-up space, you can resize the Hard Disk using some VirtualBox and Linux commands.

Some assumptions

The following steps assume you've got a set-up like mine, where:

<?php

$basePrices = [
	"6,00 € /l" => ['price' => '6,00', 'volume' => '1', 'unit' => 'l'],
	"1.88 € / 100 g" => ['price' => '1.88', 'volume' => '100', 'unit' => 'g'],
	"1.15 € / 100 gr" => ['price' => '1.15', 'volume' => '100', 'unit' => 'gr'],
	"2.33 € / 1 kg" => ['price' => '2.33', 'volume' => '1', 'unit' => 'kg'],
	"2.33 € / kg" => ['price' => '2.33', 'volume' => '1', 'unit' => 'kg'],
	"0,70 € / 10St" => ['price' => '0,70', 'volume' => '10', 'unit' => 'St'],
	"2.49 € / Stück" => ['price' => '2.49', 'volume' => '1', 'unit' => 'Stück'],
