*arr Stack (Sonarr, Radarr, Prowlarr, Overseerr, Lidarr)

The *arr apps automate finding, downloading, and importing media onto TrueNAS. They run as Docker apps on the NAS alongside qBittorrent. Everything feeds into the same library paths that Jellyfin and Navidrome scan.

Browser access from the Windows PC @ 192.168.2.200 uses the public URLs below via Cloudflare Tunnel.

Overview

App Public URL Role
Overseerr request.saxobroko.com Request UI — family-friendly front door
Sonarr sonarr.saxobroko.com TV shows — seasons, episodes, quality profiles
Radarr radarr.saxobroko.com Movies — releases, upgrades, collections
Lidarr lidarr.saxobroko.com Music — albums and artists for Navidrome
Prowlarr prowlarr.saxobroko.com Indexer manager — feeds all *arr apps

All are reachable on TrueNAS @ 192.168.2.203.

Typical workflow (TV / movies)

Overseerr request → Sonarr or Radarr → Prowlarr (indexers) → qBittorrent → import → Jellyfin
  1. Request — Someone searches in Overseerr and submits a show or film
  2. Monitor — Sonarr (TV) or Radarr (movies) adds the title and watches for releases
  3. Search — Prowlarr queries configured indexers (including Aither, my private tracker)
  4. Download — Sonarr/Radarr send the grab to qBittorrent on TrueNAS
  5. Import — When the download completes, the *arr app renames and moves files into the library root
  6. Playback — Jellyfin library scan picks up new content under A:/Media — see Adding media

Music follows the same idea via Lidarr → qBittorrent → music library folder → Navidrome.

Manual workflow (Aither)

I still use Aither directly when I want a specific release or something is not in Overseerr:

  1. Find the torrent on Aither
  2. Add to qBittorrent (or let Sonarr/Radarr grab via Prowlarr if already monitored)
  3. Wait for import
  4. Confirm in Jellyfin or on A:/Media

Details for hand-dropping files: Adding media

Root folders and paths

The *arr apps and Jellyfin must agree on where files live.

Library Typical path (Windows) TrueNAS side
TV A:/Media/Shows/ Pool dataset / SMB share — Windows network drive
Movies A:/Media/Movies/ Same share, different subfolder
Music A:/Media/Music/ (or Lidarr root) Confirm in Lidarr settings
Downloads qBittorrent incomplete/complete folders Must match *arr download client settings

On TrueNAS, these paths are datasets on the RAIDZ1 pool — Backups and pool health.

Naming conventions (critical for Sonarr/Radarr imports):

  • Shows: Show Name (Season 1 Release Year)/Season 01/Episode files
  • Movies: Movie Name (Release Year)/Movie file

Prowlarr and indexers

Prowlarr is the single place to manage indexers:

  • Add Aither (and any other private trackers) once in Prowlarr
  • Sync apps so Sonarr, Radarr, and Lidarr inherit indexer config
  • API keys and credentials live in Vaultwarden — not in SaxDocs

If searches return nothing, check Prowlarr indexer health before blaming Sonarr/Radarr.

qBittorrent integration

Each *arr app needs a download client configured:

Setting Typical value
Client qBittorrent
Host LAN address of TrueNAS or Docker network name
Category Optional — helps qBittorrent sort completed vs incomplete

Full qBittorrent notes: qBittorrent

Quality profiles and upgrades

  • Sonarr/Radarr — quality profiles prefer 1080p (or whatever is configured); upgrade allowed lets better releases replace old files
  • Lidarr — similar for FLAC vs MP3 depending on what Navidrome should serve

TODO: add current quality profile summary when locked in.

Access and auth

Public URLs go through cloudflared and block no aus WAF rules. App-level logins are separate — credentials in Vaultwarden.

Overseerr is the app I give to others for requests; admin UIs (Sonarr, Radarr, Prowlarr) are for maintenance.

Troubleshooting

Problem Check
Request stuck in Overseerr Sonarr/Radarr connection from Overseerr settings
No search results Prowlarr indexers; Aither credentials
Download never starts qBittorrent running; download client host/port in *arr
Download completes but no import Path mapping; permissions on pool dataset; category mismatch
Jellyfin missing new show Import path vs Jellyfin library root — Common Issues
