2.2 KiB

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)

Roles

  • 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

Services

NFS Exports

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

Reranker (TEI)

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.

ARR Stack

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

Technitium Backup Resolver

Serenity hosts the secondary backup Technitium node on 10.5.30.10.

  • Live stack path: /mnt/user/appdata/technitium-serenity
  • 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
  • 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

Notes

  • No GPU; reranker uses CPU-only TEI image
  • Tailscale active — reachable at 100.94.87.79 from any Tailscale node
