Resizing a disk once the volume has grown on host in a VM (Ubuntu)

The disk will not automatically resize on many platforms once more disk space was made available. Particularly in Ubuntu 16.04 Rescanning the device for size maps : echo 1 > /sys/class/scsi_device/2\:0\:0\:0/device/rescan Then standard procedures to grow the fs apply. nJoy 😉
