Adds idempotent, data-driven GGUF staging for the two new router models on
astro-orbiter alongside the production Qwen3.6-35B-A3B-UD-Q4_K_S. Both files
were already staged live (byte-exact); this commit codifies them in Ansible so
future re-runs and any new model adds are version-controlled and audit-friendly.
Changes:
- roles/llm-inference-multimodel/tasks/stage_model.yml (NEW)
Idempotent per-model task: stat -> exact byte-size guard -> conditional
get_url -> ownership/mode ensure -> notify router restart handler only on
actual download. Loops from models.yml; nothing hardcoded.
- roles/llm-inference-multimodel/tasks/models.yml
Appends the stage_model.yml loop (tagged: models) after the existing Qwen3.6
download tasks. Data driven from host_vars/astro-orbiter/vars.yml.
- roles/llm-inference-multimodel/defaults/main.yml
Adds llm_staged_models: [] default (empty = safe no-op for hosts with no
staged model list defined).
- roles/llm-inference-multimodel/handlers/main.yml
Adds 'restart llama-server-router on new GGUF' handler. Only fires when
stage_model.yml performs an actual download or corrects ownership/mode.
Normal idempotent re-runs (files already correct) do NOT fire this handler.
- host_vars/astro-orbiter/vars.yml
Adds llm_staged_models list with the two new models:
* Phi-3.5-mini-instruct-Q8_0.gguf (4,061,222,688 bytes,
bartowski/Phi-3.5-mini-instruct-GGUF)
* Meta-Llama-3.1-8B-Instruct-Q4_K_M.gguf (4,920,739,232 bytes,
bartowski/Meta-Llama-3.1-8B-Instruct-GGUF)
- playbooks/day1_deploy_llm_inference_multimodel.yml
Updates header comment: removes stale 'Semaphore broken' note, documents
the correct execution channel (Semaphore template
llm_inference_multimodel_stage_models, --tags models).
- group_vars/all/semaphore.yml
Adds llm_inference_multimodel_stage_models template entry (config-as-code).
Template is scoped to --tags models explicitly. Phase 4 (verify) is
EXCLUDED: verify.yml starts llama-server-qwen on :8002, which would collide
with the production llama-server-router.service already running on :8002.
Semaphore template created via API: project 1 / template id 19.
Execution: triggered immediately after this commit via Semaphore REST API.
- Prometheus scrape configs for node/gpu/llama-server exporters on
astro-orbiter now declared in cluster/applications/monitoring/values.yaml
(additionalScrapeConfigs), applied via ArgoCD sync instead of an
imperative kubectl secret patch from the Ansible role.
- Grafana dashboard for astro-orbiter LLM inference added as a ConfigMap
in cluster/applications/monitoring/dashboards.yaml (grafana_dashboard=1
sidecar label), replacing the role's ad-hoc kubectl apply of a rendered
Jinja template.
- ansible/roles/llm-inference/tasks/monitoring.yml: removed the kubectl
get/patch/apply tasks and orphaned grafana-llm-dashboard.json.j2
template; role now only stands up node_exporter + nvidia_gpu_exporter
and verifies they're reachable — cluster-facing config lives in Git.
- host_vars/vars.yml + inventory.yml: finalize astro-orbiter as the
llama.cpp/RTX 3090 host (jarvis user, ssh key), drop stale Ollama/AMD
vars and ollama_server inventory group superseded by the ATX rebuild.
Adds jmri_ssh_authorized_keys_extra list to support multiple authorized
keys on the jmri account. Deploys rblundon's MacBook key so xpra can
connect via SSH without a password.
- Stable udev device symlinks (/dev/jmri/nce, /dev/jmri/loconet, /dev/jmri/lcc)
- jmri-monitor: polls Leviton Decora Smart switch to start/stop JMRI automatically
- Quiet hours 1-10 AM (no polling)
- 30s off-delay before shutdown
- LCRR config cloned from Gitea (ssh://gitea.mk-labs.cloud:2221/rblundon/LCRR.git)
- ~/.jmri symlinked to LCRR repo for GitOps config management
- jmri-gui: X11 remote GUI access (PanelPro/DecoderPro) via ssh -X as jmri user
- Stops daemon, launches GUI, restarts daemon on exit if layout still on
- jmri user gets login shell + SSH key for GUI sessions
- Full JRE installed (openjdk-21-jre) for AWT/X11 support
- New ansible/roles/jmri role: installs OpenJDK 21 headless, creates
jmri service user, downloads JMRI 5.10, deploys JmriFaceless systemd unit
- Handles dialout group membership for serial device access
- Config restore task for post-reinstall recovery from GitHub backup
- host_vars/main-street-station: profile_id and serial device (TODO: fill in)
- Inventory: jmri_server group with main-street-station at 192.168.10.45
- Playbook: day1_deploy_jmri.yml (linux-baseline + jmri)
