Why do I receive an error when I try to modify my Amazon EBS volume?

Resolution

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."

There are limitations and considerations to keep in mind when you modify an Amazon EBS volume. Wait at least six hours from the start time of the previous modification. Make sure that the previous modification is complete and that the volume is in the in-use or available state before you modify the same volume.

If the volume is in optimizing state, then the Modify button is grayed out. When a volume is in the optimizing state, you can't modify the volume. 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.

1. 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.

2. Detach the original volume from its instance, and then 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.
