Overview
This chapter documents the automated media acquisition and management stack — commonly referred to as the *arr ecosystem. These services work together to monitor, search, download, rename, and organise media content automatically, then deliver it to Plex and Jellyfin.

Plex / Jellyfin
Downloads land temporarily on the Ceph OSD volume (nvme2n1, mounted at
/media/jeeves/1TB_Vol2) for high-speed write performance. After post-processing,
completed media is moved/hardlinked to the UnRAID NFS share at /mnt/Multimedia
for permanent storage.
Shared Networks
All services in this chapter are on two Docker networks:
| Network | Purpose |
|---|---|
traefik-net |
Web UI access via Traefik |
media-network |
Internal service-to-service communication (no Traefik hop) |
media-network allows *arr services to reach each other and NZBGet directly by
container hostname without going through Traefik.
