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.

resize_ebs_0

Modify the EBS volume.

resize_ebs_1

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

resize_ebs_2

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.

sudo growpart /dev/xvda 1
sudo resize2fs $(df -h |awk '/^\/dev/{print $1}')

The root file-system should now show 99GB.

df --human-readable

Filesystem      Size  Used Avail Use% Mounted on
devtmpfs        483M   60K  483M   1% /dev
tmpfs           493M     0  493M   0% /dev/shm
/dev/xvda1       99G  8.0G   91G   9% /
