Triage Guide for EFS_UNUSED_MOUNT Violation

Understand​

This violation indicates that an EFS file system has no active mounts and has exceeded the configured age threshold, suggesting it is not in use and may be safely decommissioned or archived.

Validate​

Confirm the alert by checking the describeMountTargets and describeFileSystems in AWS EFS API with the corresponding file system ID. This policy is reactive and runs twice a day.

Triage​

If left unaddressed, this file system continues to incur costs without providing value. There's minimal risk in addressing this issue as an unused file system should not impact running services.

Act​

Evaluate the importance of the file system. If it's no longer required, proceed with decommissioning or archiving it according to your organization's procedures.

Reflect​

If this violation doesn't align with your organization's priorities, consider adjusting the ageThreshold and mountThreshold variables or disabling the policy.
