You will now be able to create crash-consistent Amazon Machine Images (AMIs) of your Amazon EBS-backed multi-volume instance without requiring a reboot. The AMI created will retain data from all completed I/O operations of each volume attached to the instance. This ensures that you can launch an instance from the AMI and return to the exact state prior to creation of the image.
Previously, to ensure crash-consistency across all volumes of your instance, you either had to manually pause I/Os before creating an AMI image, or had to shut down the instance before creating their AMI or reboot the instance during AMI creation. Now, customers do not have to take any additional steps as their AMI will be crash-consistent when created from an instance.
To learn more about creating AMIs from instances, please see our documentation.
