Remediation

The remediation process depends on whether the idle EBS volume is unattached or attached but inactive. In all cases, the goal is to confirm the volume is no longer needed, archive data if required, and then securely remove the volume to avoid unnecessary costs.

Unattached and Idle Volume​

From Command Line​

Snapshots provide a cost-effective way to retain the volume data before deletion.

aws ec2 create-snapshot \
  --volume-id {{volume-id}} \
  --description "{{archival-description}}"

Delete the Volume​

Once the snapshot status is completed, the volume can be safely deleted:

aws ec2 delete-volume --volume-id {{volume-id}}

Attached but Idle Volume​

If the volume is in the "in-use" state but shows no I/O activity, further investigation is required before taking action.

Consult with the application or resource owner to confirm whether the volume is still required.

From Command Line​

Detach the Volume​

If confirmed unnecessary, detach the volume from the instance:

aws ec2 detach-volume --volume-id {{volume-id}}

Wait until the volume status changes from in-use to available.

Archive and Delete​

Once detached, the volume is now considered unattached. Follow the same steps outlined in Unattached and Idle Volume to create a snapshot and delete the volume.
