Capture london-b media stack and systemd services (#19 )

Add the full media automation stack (sonarr, radarr, prowlarr, lidarr,
readarr, whisparr), media servers (jellyfin, plex), and supporting
services (transmission, samba, ollama, promtail, cloudflared, vsftpd)
to the repo as a media_stack Ansible role.

Includes:
- Custom systemd unit files for non-package-managed services
- Config files for promtail, samba, transmission, vsftpd
- Cron jobs for movie-rename-fix, sonarr/radarr midnight restarts
- Updated deploy.yml to wire the role into london-b's stage
- Updated london-b docs with full service inventory

Backup script (backup.sh) already covered by the existing backup role.
Node/systemd exporters already covered by existing monitoring roles.

Closes PESO-92

Raw Blame History

london-b

Primary storage and media server. The workhorse of the fleet.

Overview


Location	London (NW9)
OS	Ubuntu 24.04
Tailscale IP	100.84.65.101
Role	Storage, media serving, Docker services

Hardware

Component	Spec
CPU	AMD Threadripper 3970X (64 threads)
Memory	64 GB
GPU	Nvidia GTX 980
Boot disk	500 GB
Storage pool	~64 TB (ZFS)

This machine is ridiculously overpowered as a media server. It's my old gaming/workstation PC repurposed into server duty. The GPU helps with Plex transcoding but the CPU can handle it fine on its own.

Storage

ZFS pool hdd: 3× RAIDZ1 vdevs, 8 drives total.

Metric	Value
Used	46 TB
Free	18 TB
Total	~64 TB
Usage	72%
Scrub	Weekly (Sundays)

RAIDZ1 tolerates one drive failure per vdev. With this many drives and this much data, ZFS checksumming is essential — silent data corruption on spinning disks is real and you don't want to find out about it years later.

Systemd Services (non-Docker)

The media automation suite and several supporting services run as native systemd units, not in Docker:

Service	Unit Name	Notes
Sonarr	sonarr	Package-managed (mono)
Radarr	radarr	/opt/Radarr, custom unit
Prowlarr	prowlarr	/opt/Prowlarr, custom unit
Lidarr	lidarr	/opt/Lidarr, custom unit
Readarr	readarr	/opt/Readarr, custom unit
Whisparr	whisparr	/opt/Whisparr, custom unit (disabled)
Plex	plexmediaserver	Package-managed
Jellyfin	jellyfin	Package-managed
Transmission	transmission-daemon	Package-managed
Samba	smbd	Package-managed
Ollama	ollama	/usr/local/bin, custom unit
Promtail	promtail	Custom unit, ships logs to Loki
Cloudflared	cloudflared	Tunnel to Cloudflare
vsftpd	vsftpd	FTP server for /hdd/ftp
systemd_exporter	systemd_exporter	Ansible-managed
node_exporter	node_exporter	Ansible-managed

Docker services: Nextcloud AIO, Jellyseerr, Navidrome, slskd, Miniflux, smartctl-exporter, plex-exporter.

Cron Jobs

Schedule	Job
Every hour	`/root/scripts/movie-rename-fix.fish`
Midnight daily	`systemctl restart radarr`
