For example, in a scenario where you have an auto-scaling group of size 1 that launches a spot instance which continually uses the same root EBS volume.


Not natively as far as I am aware, and not the root volume. You can however create a launch script to mount the volume as a secondary drive when the instance is spun up

  • Can you use pivot_root to remap the secondary volume as the root fs in the launch script? – Alex R Jul 23 '15 at 3:24
