vh 5402568b76 feat(esh-ml1): RTX 2000E Ada on esh-pve serves embed + rerank as a LiteLLM failover 
esh-pve: NVIDIA 580.178.04 (open modules, DKMS) installed on the host from
NVIDIA's .run and loaded live, no reboot. nvidia-persistenced unit creates the
device nodes before pve-guests; the T400's vfio-pci ids and `blacklist nvidia`
retired. playbooks/esh-pve-nvidia-host.yaml.

esh-ml1: CT 110, unprivileged Debian 12, 10.0.50.80, GPU nodes via devN,
NVIDIA userspace from the same .run (--no-kernel-modules), docker-ce +
nvidia-container-toolkit (no-cgroups). playbooks/esh-ml1-lxc.yaml. Not in the
vzdump job on purpose. DNS esh-ml1.esh.internal.

stacks/embed-rerank: Qwen3-Embedding-0.6B :8001 + bge-reranker-v2-m3 :8013 on
the same vLLM v0.24.0 digest and flags as fv-ml1. Measured parity: embed
cosine FV-vs-ESH median 0.999908 (min 0.999772), inside both self-noise
floors; rerank max |delta| 0.000145 vs floor 0.000181, identical ranking.

litellm: qwen3-embedding and reranker gain an esh-ml1 deployment at order 2
behind fv-ml1 (order 1). Order fallback proven with throwaway groups:
refused primary +0.15 s, host-down primary ~18.7 s per call, dead-only 500.

Also: repaired the DB-only alias reranker-a3-bge-v2-m3, dead since the
fv-ml1 relocation (still named 10.250.50.54); documented the third
unkillable homepage wedge on esh-docker-vm.

esh-docker-vm

General-purpose Docker host at the ESH home-lab site (esteban.net / 10.0.0.0/8 space). VM, no GPU. Separate scope from the PFI colo work but tracked here because it's part of the same fleet.

Network

  • LAN IP: 10.0.50.45
  • FQDN: esh-vm-docker.esteban.net
  • Subnet: 10.0.50.0/24 (inferred from macvlan config)
  • SSH: standard port 22
  • Traefik entrypoints: 80/443 terminate here; DNS-01 challenge via AWS Route53; protected by CrowdSec Traefik plugin

Hardware

  • CPU: 16 vCPU (QEMU virtual — VM)
  • RAM: 15.6 GB
  • GPUs: none
  • Storage: 250 GB root (ext4) + NFS mounts from 10.0.50.50
  • OS: Debian 12 (bookworm), kernel 6.1.x
  • Docker: running (daemon socket at /var/run/docker.sock; also listens on :2375)

Key paths

Path Purpose
/opt/docker/compose/<stack>/ Compose files (also a git repo)

Latest snapshot: system-details.txt (regenerate as needed).

Cross-site monitoring

Like nh3-docker, this host runs Dozzle and Beszel agents that report back to the hubs on ana-docker, so container logs and metrics show up alongside PFI hosts in the shared dashboards.

Notes

  • Macvlan for Home Assistant — the HA container gets its own LAN IP (10.0.50.46) via a macvlan network on ens18, avoiding NAT so multicast/mDNS for HA discovery works cleanly.
  • External Postgres — Paperless-ngx connects to a DB running elsewhere (10.0.50.60:5432), not a sidecar. Paperless creds in that compose file currently look like defaults; rotate before exposing.
  • Volume backups already in place — paperless-ngx and pgadmin include offen/docker-volume-backup:latest sidecars that tar named volumes to /mnt/backup/docker/esh-vm-docker/<stack>/. When the fleet-wide restic plan lands, decide whether to subsume these or leave the per-stack sidecars alone.

Placement rule

Home-lab workloads for the ESH site go here. Not part of the PFI colo topology.

⚠ Recurring: homepage wedges unkillably (3× — 2026-06-03, 2026-09-18, 2026-09-24)

The Homepage container stops answering (Uptime Kuma: timeout of 16000ms exceeded; healthcheck Connecting to 127.0.0.1:3000 times out) and cannot be stopped. Signature captured 2026-09-24 ~2224 PT, guest kernel 6.1.0-41-amd64:

  • one node thread in D state in vm_mmap_pgoff — waiting for its own process's mmap_lock for write, with no visible holder (every other thread sat in futex_wait; a scan of every task's kernel stack found no reader in a fault, NFS or access_remote_vm path except the ps calls queued behind it).
  • docker restart → "tried to kill container, but did not receive an exit event"; the process then sits in exit_mmap (uninterruptible) with PID 1 of the container in zap_pid_ns_processes. The June entry in archival-memory records the same exit_mmap end state.
  • The rest of the VM is fine: DNS (AdGuard) answered, 17 other containers up.

⚠ Diagnosing it can hang your shell. ps, pgrep and docker top read /proc/<pid>/cmdline|environ, which takes the same lock, so they block in D state too. Read /proc/<pid>/task/*/stat and sudo cat .../stack instead (ssh infra-ops@10.0.50.45, NOPASSWD).

Only a VM reboot clears it, and this VM is ESH's DNS resolver, so the reboot is a short ESH-wide DNS outage — schedule it. Root cause not established; a kernel-side mmap_lock problem is the leading guess, not a finding. Moving Homepage to ana-docker (as was done for Uptime Kuma on 2026-09-21 for the same box's history) would take the dashboard out of this failure domain.
