I had an EC2 instance which was EBS backed (i.e. boots off an EBS volume). The hardware appears to have crashed. I'm having trouble getting it back, which is frustrating as the whole point of having an EBS-backed volume is that the disk image should be robust against CPU crashes.
First I tried to make a new AMI based on that machine, but the new AMI was stuck in pending. Diving in with the command-line tools I saw that the machine couldn't stop properly. So I did
But then I couldn't make an AMI from a detached volume. I tried making a new instance and attaching the EBS volume to it (after detaching the one it came with), and booting it, but that one failed to boot saying
"State Transition Reason: Server.InternalError: Internal error on launch"
I'm assuming there has to be a way to get the drive back and running again -- that's the point of EBS, right? But how?
