Extend Vagrant's Disk

TurnToJPG -->

In Vagrantfile, edit the following definition:

  config.vm.provider "virtualbox" do |vb|
  #   # Display the VirtualBox GUI when booting the machine
  #   vb.gui = true
  #
  #   # Customize the amount of memory on the VM:
    vb.memory = "1024"
    file_to_disk = File.realpath( "." ).to_s + "/disk.vdi"
    if ARGV[0] == "up" && ! File.exist?(file_to_disk) 
      puts "Creating 5GB disk #{file_to_disk}."
      vb.customize [
        'createhd', 
        '--filename', file_to_disk, 
        '--format', 'VDI', 
        '--size', 5000 * 1024 # 5 GB
        ] 
      vb.customize [
        'storageattach', :id, 
        '--storagectl', 'SATA', 
        '--port', 1, '--device', 0, 
        '--type', 'hdd', '--medium', 
        file_to_disk
        ]
    end
    #config.vm.provision "shell", path: "scripts/add_new_disk.sh"
  end
  config.vm.provision "shell", path: "scripts/add_new_disk.sh"

The add_new_disk.sh should be written like following:

set -e
set -x

if [ -f /etc/disk_added_date ]
then
   echo "disk already added so exiting."
   exit 0
fi
