Resize Cloud9 Instance Root Volume

Resize Cloud9 EBS

The default 10GB is may not be enough to build the application docker images. Thus, let us resize the EBS volume used by the Cloud9 instance.

To change the EBS volume, please do

  1. Select the Cloud9 instance in the EC2 console deep link to get there
  2. Click the Storage : Section
  3. Click on the Volume ID. That will take you to the EBS Volume page details.


Modify the EBS volume.


Choose a new volume size (e.g. 100GB).


Please make sure changes went through, and the EBS volume now reflects the new size of the volume.

Resize FS

Changing the block device does not increase the size of the file system.

To do so head back to the Cloud9 instance and use the following commands to reboot the instance. It could take a minute or two for the IDE to come back online.

sudo reboot

The root file-system should now show 100GB.

df --human-readable
