How to extend-resize Linux root partition on AWS EC2

In this tutorial we will see how to increase or resize the linux root partition on aws ec2 instance using aws webconsole.

You must have running instance to resize your root partition. For testing purpose you can launch an free tier linux instance.

In this scenario I have launched an ubuntu free tier instance with 8gb volume size root partition as you can see in the below image

1. First note down some important things like below :-

1. Avaibality zone :- us-west-2c
2. Instance ID :- i-00fbe20bba17f353b
3. Root device :- /dev/sda1

2. To resize it to 16gb we need to stop the instance :-

Select the instance and hover over Action menu and you will see "Instance state" hover your mouse and select "Stop"

3. Go to EBS Block Storage and select Volumes to take snapshot :-

Next fill in the name and description of your snapshot like below

Check the status of the snapshot whether it is in "pending" state or completed. It should be in the completed state to resize partition.

4. Create a New Volume by selecting taken snapshot :-

You will have a pop window where you have enter the new size that you want for your partition and you have to select the same zone which have noted earlier in step 1.
