This seemed to work. I was able to export the pool and reimport it without a problem. I'll use this for testing, however, correct me if I'm wrong, but this should still work without attaching it as a disk device, correct? Prior to testing this, I tried using the the files again without mounting and I received the error stating that it was missing one of the files. It clearly identified disk1.dd as present, but was unable to find disk2.dd.
