Why can't I modify my Amazon EBS volume?
Last updated: 2022-11-29
I'm trying to modify my Amazon Elastic Block Store (Amazon EBS) volume, but I can't.
When you modify an Amazon EBS volume, you might receive the following error:
Modify Volume Request Failed for volume vol-#######
You've reached the maximum modification rate per volume limit. Wait at least 6 hours between modifications per EBS volume.
Also, you might notice that the Modify button is grayed out. This is because the volume is in the "optimizing" state. When a volume is in the "optimizing" state, you can't modify it. For more information, see Why is my Amazon EBS volume stuck in the Optimizing state when I modify the volume?
If you can't wait six hours to modify your volume, then complete the following steps.
Note: The following resolution requires instance downtime.
- Create a volume from the snapshot of the original volume.
Note: If you don't have a snapshot of the original volume, then first create one.
- Detach the original volume from its instance, and replace it with the volume that you created from the snapshot.
Note: Make sure that the instance is in the "stopped" state to prevent any new data from being written to the volume.
