Data Flow#

User
└─► Overseerr (request)
    └─► Sonarr / Radarr (pick release, apply quality profile)
        └─► Prowlarr (search indexers)
            └─► SABnzbd (download + unpack to /mnt/downloads)
                └─► Sonarr / Radarr (import → /mnt/media/tv or /mnt/media/movies)
                    └─► Plex (detects new file, scans library, ready to stream)

Storage Paths#

Path	Used by	Description
`/mnt/media/movies`	Radarr, Plex	Final movie library
`/mnt/media/tv`	Sonarr, Plex	Final TV show library
`/mnt/downloads`	SABnzbd, Sonarr, Radarr	Download staging area

All three paths come from the same ZFS pool. Sonarr and Radarr see both /mnt/downloads and /mnt/media — this is what allows them to use hard links during import instead of copying files.

VM and LXC IDs#

ID	Type	Service
`lxc/103`	LXC	Plex Media Server
`lxc/104`	LXC	n8n
`qemu/102`	VM	Docker host — Sonarr, Radarr, SABnzbd, Overseerr
`node/proxmox`	Host	Proxmox VE node

Network#

All Docker containers run on a shared internal network (media_net). They communicate by container name, not by port or IP. The only ports exposed to the LAN are the web UIs of each service.

Service	LAN Port
Plex	32400
Overseerr	5055
Sonarr	8989
Radarr	7878
Prowlarr	9696
SABnzbd	8080

None of these are exposed to the internet by default. Remote access to Plex is handled by Plex's own relay service.
