Serenity

NAS, media ingestion, and CPU-based AI inference.

Hardware

Component	Details
IP (LAN)	10.5.30.5
IP (Tailscale)	100.94.87.79
OS	Unraid 7.2.4
CPU	Dual Intel Xeon X5690 (6c/12t each — 24 threads total)
RAM	102 GB
GPU	None (Matrox G200 IPMI only)

NAS — primary storage for Docker volumes, media, and backups via NFS
Media ingestion — full ARR stack (Sonarr, Radarr, Prowlarr, qBittorrent, etc.)
Reranker host — CPU-based TEI reranker for the AI RAG pipeline

Export	Mount on PD	Purpose
`/mnt/user/data`	`/mnt/unraid/data`	General Docker volumes
`/mnt/user/immich`	`/mnt/unraid/immich`	Immich photo library

Note: NFS mounts on PD are not automatic at boot. Run after every TrueNAS restart:
sudo bash /mnt/tank/docker/scripts/mount-unraid-nfs.sh

Text Embeddings Inference reranker for OpenWebUI RAG pipeline.

Setting	Value
Model	`BAAI/bge-reranker-v2-m3`
Image	`ghcr.io/huggingface/text-embeddings-inference:cpu-latest`
Port	`9787`
Volume	`/mnt/user/appdata/reranker`
LiteLLM model name	`reranker`
API base	`http://10.5.30.5:9787`

Moved from PlausibleDeniability (port 8787) to Serenity (port 9787) on 2026-05-09. CPU-only inference is acceptable for RAG reranking workloads.

Managed via Unraid Community Apps. See Unraid dashboard for individual service ports and status.

Serenity hosts the secondary backup Technitium node on 10.5.30.10.

Live stack path: /mnt/user/appdata/technitium-serenity
Live secrets file: /mnt/user/appdata/technitium-serenity/.env
Resolver bind IP: 10.5.30.10
Config is refreshed from PD's live Technitium directory by the PD-side sync runner every 15 minutes
The live .env is also backed up into the encrypted PD secrets repo as env/technitium-serenity.env
Same-host checks from Serenity to 10.5.30.10 are unreliable because the resolver sits behind macvlan networking; verify from another LAN peer instead
