I have followed your guide on installing sonarr, radarr, etc on OMV and found it invaluable - thank you. I have everything up and running (except Mylar - its not sending requests, but I'll get that sorted).
I have installed it on a Raspberry Pi 3.
My issue / question (which I hope you can help with) is this: I've run out of free space on my SD card. I believe that it is because plex stores the metadata in the /home/dockerperson/.config/plex/Library/Application Support/Plex Media Server/Metadata folder. The metadata folders can become voluminous.
Is there a way to configure the set up so that the metadata is stored elsewhere?
