After a few weeks of running in a degraded state I have all my Sync nodes back online. Some very basic maintenance at my parents for thanksgiving got me working with my problem node. I ended up swapping out the Pi at my parents place for a Mac Mini that I stopped using after I got my latest Apple TV. That mini had a replica copy on a larger hard drive so the swap out was less about any issues with the Pi vs I took the opportunity to upgrade while i was there.
I need to call my sync network something other than Pi Net since right now the majority of the nodes are not Raspberry Pi’s.
