[Starcluster] InvalidInstanceID.NotFound on Disk Creation

[Austin Godber]

Has anyone else seen an InvalidInstanceID error when creating a disk?

I got the following error when creating a disk:

volume.py:186 - ERROR - exception thrown: EC2ResponseError: 400 Bad Request
<?xml version="1.0"?>
<Response><Errors><Error><Code>InvalidInstanceID.NotFound</Code><Message>The 
instance ID 'i-913c54fb' does not 
exist</Message></Error></Errors><RequestID>XXXXXX</RequestID></Response>

The instance definitely started since I see it as terminated in my AWS 
console.  Oh, I bet I know what happened.  I was actually creating TWO 
disks at the same time.  I bet that disk creation shuts down all 
instances in the @sc-volumecreator group.  And when the first one was 
killed, the second one was killed along with it.
