EC2 Xenial instance-store images are too small

[Mat Schaffer]

The latest xenial ec2 instance-store images have a ~2G root volume:

 - ubuntu/images/hvm-instance/ubuntu-xenial-16.04-amd64-server-20170329 (ami-c164f0a1 in us-east-1)
 - ubuntu/images/hvm-instance/ubuntu-xenial-16.04-amd64-server-20170330 (ami-4e29bd2e in us-east-1)

This seems to be not enough to manage a kernel install given the apt cache and other things on the disk.

Images prior to that (e.g., ubuntu/images/hvm-instance/ubuntu-xenial-16.04-amd64-server-20170307 - ami-44c14e24 in us-east-1) have a ~9G root volume.

This seems somewhat related to https://bugs.launchpad.net/cloud-images/+bug/1463963 but I'm not familiar enough with the cloud-images build process to say if it's the same root cause so I thought it might warrant its own report.

Feel free to close if this is not the case.

Thanks in advance for any advice or assistance!

Hi,

i just wanted to mention that we are having a similar issue with the EU-west-1 images released on 2017 03 30 with the AMI ID : ami-abc5facd

the system is not able to run a normal aptitude update or any other commands since its root device is instantly full :(

Please revert the changes done to something more usable.

Thank you

Hi All, We're working on fixing this issue. Thank you for filing a bug!

Zesty (17.04) daily build 20170412.1 is 10GB in size for PV/HVM instance-store AMIs. This fix will work back into yakkety and xenial once testing is complete.

Yakkety (16.10) daily build 20170413 (and later) has a 10GB root volume for PV/HVM instance-store AMIs. This fix will work back to xenial as well.

To get a list of daily yakkety images from this year sorted by creation date you can run:
$ aws ec2 describe-images --owners 099720109477 --filter "Name=name,Values=ubuntu/images-testing/*ubuntu-yakkety-daily-amd64-server-2017*" | jq -s '.[] | .["Images"] | sort_by(.["CreationDate"])'

Xenial (16.04) daily and release builds 20170414 (and later) have a 10GB root volume for PV/HVM instance-store AMIs.
