So I don't need to do anything on the primary and I can use the existing device where the data lives now as the lower-level location? I know about the internal meta data at the end and allowing for it. So for my secondary can I do the same with that? It has an existing OS and different files in /etc than the primary and I want to make it identical to the primary so in case of the primary failing the secondary would become a live system identical to the primary. How do I achieve this? How do I remove the files from the secondary and populate the secondary with matching data from the primary?
