That is awesome. I have two 8TB Roamios which were built using mfsr. I guess at the time it was not known how to build drives that large with MFSTools. I did something like this, way waaaaay back in the day. I set up a Series2 DirecTivo on a 2TB drive by starting with the minimal MFS image that had only a single MFS pair, and manually creating the second and third pairs, while keeping them under 1TB. Is this process doable with the current version of mfs tools, or do I need to wait for the next one? Thanks!
