How do I resolve errors that I receive when I create an Amazon EBS volume from a snapshot?

Resolution

Note: If you receive errors when you run AWS Command Line Interface (AWS CLI) commands, then see Troubleshooting errors for the AWS CLI. Also, make sure that you're using the most recent AWS CLI version.

The following are reasons why you might receive an error when you try to create an Amazon EBS volume from a snapshot.

The snapshot no longer exists

When another AWS account creates and shares a snapshot and then deletes the snapshot, you can still see the shared snapshot in your account. If you try to create an EBS volume from the deleted snapshot, then you might receive the snapshot doesn't exist error.

Make sure that the snapshot that you want to create a volume from still exists in the other account. Also, make sure that the snapshot exists in the same AWS Region that you want to create the volume in.

You try to create an unencrypted volume from an encrypted snapshot

When you try to create an unencrypted volume from an encrypted snapshot, you receive the following error message in the AWS CLI:

"An error occurred (InvalidParameterCombination) when calling the CreateVolume operation: EncryptedVolume parameter [false] is inconsistent with snapshot encryption state [true]"

You can't create an unencrypted volume from an encrypted snapshot. To check whether you encrypted the snapshot, see How do I view encryption information about my AMI or snapshot?

AWS KMS key authentication fails

You successfully create an encrypted volume from an encrypted snapshot. However, when you try to access the volume you get a volume doesn't exist error. This might happen when AWS Key Management Service (AWS KMS) key authentication fails for volume encryption or decryption. AWS asynchronously authenticates AWS KMS keys. For more information, see Amazon EBS encryption.

To resolve this issue, see Why does the new Amazon EBS volume that I create from an encrypted snapshot not exist?

The volume size is smaller than the original volume, or the size isn't within storage capacity

Amazon EBS doesn't support the reduction of a volume's size. If you try to create a volume that's smaller than the original volume that you use to create the snapshot, then volume creation fails. Make sure that the volume is at least the same size as the original volume. You can make the volume size larger, but you must keep the size within storage capacity.
