How to grow a partition in Linux

This guide will walk you through the steps required to grow a partition in Linux. You will have to reboot through this guide.

1. If possible, make a snapshot.

Often, you will want to grow the partition table because you made your virtual hard disk too small, and you tried to extend it in your hypervisor, only to find out that your partition is still the same size as it was before.

	time.sleep(max(0, i - 0.005))
	now = time.time()
	while now - then - i < 0:
		now = time.time()
	print(round(now - then - i, 5))
