I'm new to Amazon AWS and I've been tasked to move a company's web app (LAMP) to amazon aws. I setup an EC2 and an RDS. I successfully setup apache, mysql and phpmyadmin. I ran into problems when I started to transfer their web app over to our EC2. The eror message "disk space full" So in the console I resized the volume from 8GB to 16GB. But the root mount is still set to 8GB..
You need to extend the Linux volume size. Basically, the disk is bigger, but you need to tell Linux to use the disk.
I know SF likes steps copied in, just in case the source disappears. AWS documentation is reliable regularly updated, so in this case I won't copy the steps in.
