I've attached a snapshot of another volume to a test Instance on AWS. Both instances run Ubuntu Lucid.
I've tried to unmount the test instance but it's claiming that the device is busy. I think this may be due to the fact that I copied the root volume from the other instance, so there are dupes of the bash executables.
Is there now a relationship between my real volume and the snapshotted clone? Can I just terminate the test instance, or will that corrupt the volume?
