There seems to be an issue with the notification settings or firmware of your EX4100 NAS, as the email alert about degraded storage was only sent after you powered the NAS back on. To ensure timely alerts in the future, check that your email notification settings are correctly configured and that notifications for critical events are enabled. Make sure your NAS firmware is up-to-date, as updates often fix bugs and improve performance. Testing the email alert system can help confirm it’s functioning properly. Reviewing the event logs might provide insights into why the initial alert wasn’t sent. Ensure there are no network issues hindering the NAS’s ability to send emails, and check with your email provider to confirm notifications aren’t being blocked or marked as spam. If the problem persists after these steps, contact the manufacturer’s support team for further assistance.
This alert is far too late. I know the array is degraded now I just replaced the drive. The alert should have been sent when the disk error was detected.
