Hi,

I have installed Bitnami Drupal AMI on AWS EC2 instance. I have a need to expand its 10gb ebs volume to 20gb.

I have modified the volume using AWS console to 20GB. But now I need to tell to Ubuntu that the volume is larger. When I run lsblk command it shows that the "xvda" size is 20GB but the xvda1 is still old 10gb. I tried the command sudo resize2fs /dev/xvda1 but that says its already resized. Anyway the new amount of space is not in use, df -h command shows the /dev/xvda1 still has 10gb size. So which are the steps to expand the Bitnami AMI EBS volume size? Is there another way or is this the only way?

UPDATE:

These are the steps to increase EBS Volume size without any reboots or new instance launches:

Modify volume to new size (for example from 10gb to 12gb)
command "lsblk" shows that Ubuntu does not yet use the new 12gb size
run command: sudo growpart /dev/xvda 1 (or what ever name you have instead xvda)
run command: sudo resize2fs /dev/xvda1 allocates the new size for Ubuntu
done, you have allocated more space to your EBS.

with command: df -h you can see that the new size is really in use

In order to expand a disk you need to start another instance, mount the ebs disk and change the partitions. This is not a straight forward process but it is doable.

As an alternative approach you can add a new AWS volume and move some data there. Check our how-to guide https://docs.bitnami.com/aws/how-to/attach-ebs-volume/ I hope it helps!
