EC2 Instance Unreachable After Failed Status Checks

0

One of our instances reported a failed status check and became unreachable. Tried rebooting and start/stop to no avail. Usually that works. Also tried creating a new instance based on a snapshot and have the same issue. Tried changing instance type from t2 to m4 as well.

Any ideas?

Thanks.

Not sure what type of EC2 instance it is but here are few options to look for

  1. Troubleshoot instances with failed status checks - https://docs.aws.amazon.com/AWSEC2/latest/UserGuide/TroubleshootingInstances.html
  2. Why is my EC2 Linux instance unreachable and failing one or both of its status checks? - https://aws.amazon.com/premiumsupport/knowledge-center/ec2-linux-status-check-failure/
  3. Why is my EC2 Windows instance down with an instance status check failure? - https://aws.amazon.com/premiumsupport/knowledge-center/ec2-windows-instance-status-check-fail/
  4. Why is my EC2 Windows instance down with a system status check failure or status check 0/2? - https://aws.amazon.com/premiumsupport/knowledge-center/ec2-windows-system-status-check-fail/

  • I've checked these but unfortunately system logs are empty. Also looked at the serial console and also empty. Its a Linux instance.

    Instance screenshot says its in rescue mode with a missing /boot/grub/i386-pc/normal.mod file
