Recover EC2 instance created from AMI of other EBS instance

  • 772

It rebooted, then won't restart.

Forgive me if I'm short on details - still collecting them. It is an EBS image created from an AMI which was created from another EBS image.

The notes at end may provide some insight.

Is this recoverable? because it is an ebs instance, i can try to attach to it via another image, but I'd rather recover the running EBS.. and would like to understand what happened, is happening.

Any other suggestions very welcome.

    Looks like it was something wrong with /etc/fstab. Basically

    1. take a snapshot of broken ebs (as precaution)
    2. detatch broken ebs from /dev/sda1 on relevant machine
    3. created new ebs from snapshot
    4. attached from running server and
    5. edited /etc/fstab detached and
    6. reattached to original ebs instance at /dev/sda1 (aws gives error but it worked!)
