Exanding size of your current EBS root volume

In some cases you may need to increase the size your EC2 instance root volume. Here are the steps to do this:

1. Create a volume from an existing EBS snapshot :
aws ec2 create-volume --snapshot-id snap-YourVolumesSnapshot --size 10 -- availability-zone az-asdf-1a 

2. Stop the instance:
was ec2 stop-instances --instance-id i-YourInstanceId

3. Detach the current volume:
was ec2 detach-volume --volume-id vol-TheSmallDefaultVolume

4. Attach the new volume:
was ec2 attach-volume --volume-id vol-TheLargerVolume --instance-id i- YourInstanceId --device /dev/sda1

5. Log into your bastion host:
ssh -i YourFile.pem ec2-user@10.__.__.__

7. Start the instance:
aws ec2 start-instances --instance-id i-YourInstanceId

8. Check the file system size: (It will still be the smaller size)
df –h

9. Resize the file system to the size of the volume
sudo resize2fs /dev/sda1

10. Check the file system size again:
df –h
