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?

terminating the snapshot will in no way affect the original volume.

You might try lsof | grep /snapshot/mount/point to try and find any open files, if you still want to try to unmount it. But really, a proper umount will only serve to make sure files in the snapshot are safe. If you don't care about the snapshot, kill the sucker!
