I think this is the same issue as #19406 : changes to ebs_block_device in your Terraform script are not actually applied to AWS on terraform apply : the ebs_block_device configuration is only used to create the EBS volume.

Both this and #19406 still seem to be existing bugs, so this issue should not be made stale.
