Update
After banging enough rocks together I have managed to get everything working. It seems that my initial problems were caused by configuring the network controller to a manual ip instead of letting it auto select. I have set the eth0 mac address in my router as a static rout instead trying to set up the static route in the rockstor network configurations.
After much tinkering i was able to get plex working along side of samba. It turns out my issues this morning were caused my me neglecting to change the owner of Config share from root to Plex, and the group to Users.
After uninstalling and reinstalling the Plex rock-on i was able to use the ui as normal and clamed the server. The server was unavailable to anyone outside my internal network but that was quickly fixed by taking the “Public” ip address and port number that the Plex web ui page Server>Settings>Remote Access and plunking it into my routers port forwarding/port triggering reservations.
So huzza Samba Works, Plex works and talks to the web as designed, i can move the box off of my test bench and back in to the closet where it belongs.
I want to give a shoutout to this post Plex no longer available on network - #9 by Flox @phillxnet for pointing me at the network issue and to @Flox comment in the above post that provided the command
docker logs plex-linuxserver.io
Which clued me to the config folder permissions not being set properly. Thanks everyone admins can lock this thread and i hope future people find this enlightening
