I have scoured the forums for this information and I find various answers to ALMOST my question. So I'm going to list what I've tried, and what I hypothesize, and if someone would be kind enough to tell me if it would work (and if not, what will) that would be awesome.
Set up PMS on my primary 120GB Windows drive (C:). It worked PERFECTLY.
The downside was that the metadata used 80GB of space, so I decided it needed to move.
Tried following instructions from here to move metadata and related folders to a 3TB WD MyBook (G:), but then server wouldn't load (500 error).
Uninstalled everything, moved the entire library to G:\Movies and G:\TV
Installed Plex to G:\Plex
I can now connect to the PMS from everywhere across the network but NONE of the metadata shows up the way it did while running from C:\
I've Analyzed, Refreshed, and FileBotted over and over again. No joy.
I have a limited knowledge of networking, and need to know what folders do I have to move so that PMS will run the beautiful way it did when it was all installed on C:\ yet not hog my entire hard drive.
