Terraform Configuration Files

resource "aws_instance" "test_instance" {
  ...
  root_block_device {
    volume_type           = "gp2"
    volume_size           = "30"
    delete_on_termination = "false"
  }

....
  ebs_block_device {
    device_name           = "/dev/sdg"
    volume_type           = "gp2"
    volume_size           = "30"
  }

....

Debug Output

Expected Behavior

when the template is run for the first time it will create instance with root and ebs volume which is fine. later if we want to increase the ebs volume size it should increase the size

Actual Behavior

doesn't increase the size

Steps to Reproduce

1. terraform init
2. terraform apply
3. Increase the ebs_volume size
4. terraform apply
   nothing changes

The same applies for iops in case of io1 type, terraform doesn't detect iops and size changes in ebs_block_device.
