Hey, is that a bug or by design?

m5d.2xlarge

Amazon Linux 2 AMI (HVM), SSD Volume Type

has by default 1x300GB SSD disk attached. When I create such instance using

new aws.ec2.Instance

everything is fine and ec2 instance is being provisioned with

/dev/nvme1n1    296G

volume. However, when I use exactly the same instance size and AMI (ami-0cc293023f983ed53), but create it in autoscaling group

new awsx.autoscaling.AutoScalingLaunchConfiguration

it has only ~55GB disk attached (

/dev/nvme1n1     53G

). Can you please help me to understand why and how I can increase disk size?
