ce7b8c2b2e add pvc-autoresizer for automatic PVC expansion before volumes fill up [ci skip]
Deploy topolvm/pvc-autoresizer controller that monitors kubelet_volume_stats
via Prometheus and auto-expands annotated PVCs. Annotated all 9 block-storage
PVCs (proxmox-lvm) with per-PVC thresholds and max limits. Updated PVFillingUp
alert to critical/10m (means auto-expansion failed) and added PVAutoExpanding
info alert at 80%.

d49acebd8e migrate ebooks-calibre to proxmox-lvm, update storage docs [ci skip]
- Migrate ebooks-calibre-config-iscsi (2Gi, 2380 files) to proxmox-lvm
- Update docs/architecture/storage.md: document Proxmox CSI as primary
  block storage, mark democratic-csi iSCSI as deprecated
- Add full migration plan to docs/plans/

dd59512153 migrate iSCSI block volumes from democratic-csi to Proxmox CSI [ci skip]
Replace TrueNAS iSCSI (democratic-csi) with Proxmox CSI plugin for all
block storage PVCs. Eliminates double-CoW (ZFS + LVM-thin) and removes
the iSCSI network hop for database I/O.

New stack: stacks/proxmox-csi/ — deploys proxmox-csi-plugin Helm chart
with StorageClass "proxmox-lvm" using existing local-lvm thin pool.

Migrated PVCs (12 total):
- Phase 1 standalone: plotting-book, novelapp, vaultwarden, nextcloud, prometheus
- Phase 2 StatefulSets: CNPG PostgreSQL (2), MySQL InnoDB (3), Redis (2)

All services verified healthy post-migration.

337da2184d add upstream fallback to containerd registry mirrors
When the pull-through proxy (10.0.20.10) is down, containerd now falls
back to the official upstream registries (registry-1.docker.io, ghcr.io)
instead of failing. Also cleans up stale disabled registry mirror dirs
and removes unnecessary containerd restart from the rollout script.

dd461beb33 add registry blob integrity checker to self-heal corrupted cache
The cleanup-tags.sh + garbage-collect cycle can delete blob data while
leaving _layers/ link files intact. The registry then returns HTTP 200
with 0 bytes for those layers, causing "unexpected EOF" on image pulls.

fix-broken-blobs.sh walks all repositories, checks each layer link
against actual blob data, and removes orphaned links so the registry
re-fetches from upstream on next pull.

Schedule: daily at 2:30am (after tag cleanup) and Sunday 3:30am
(after garbage collection). First run found 2335/2556 (91%) of
layer links were orphaned.

a2b1b0e817 remove caretta network mapper to free 3Gi cluster memory
Caretta eBPF DaemonSet was using 600Mi x 5 nodes = 3Gi total for
non-critical network topology visualization. Removing it to free

cbea959966 feat(ebooks): mount calibre-library PVC in book-search for permission fixing

46444e0306 openclaw: remove install-dotfiles init container to reduce NFS writes
The init container was cloning the dotfiles repo via git on every pod
start, causing 200+ small NFS writes that amplified through ZFS.
Dotfiles already exist on NFS from a previous clone — no need to
re-clone on every restart. To update dotfiles, run git pull manually.

Also cleaned up stale Uptime Kuma files (1.6GB old SQLite DB + 289MB
error log left over from migration to MariaDB).

06490b0634 reduce Prometheus cardinality round 3: drop 44k more series
- cadvisor: drop unused network error/dropped counters, unused cpu
  metrics (load_avg, system, user), unused memory metrics (cache,
  failcnt, kernel, mapped_file, max_usage, rss, swap, active/inactive)
- kubelet: drop all unused histogram buckets (storage_operation, csi,
  volume_operation, image_pull, http_requests, rest_client, pod_worker,
  volume_metric, cgroup_manager) + kubernetes_feature_enabled
- apiserver: drop flowcontrol/rest_client histograms, longrunning_requests
- traefik: drop all router-level metrics (keep service + entrypoint)
- service-endpoints: drop coredns histograms, node_filesystem_*

Post-relabel: 332k → 99k (-70%), ingestion: 5,480 → 1,659 samples/sec (-70%)

a9ca65bc31 reduce Prometheus cardinality round 2: drop 137k more series
- fix traefik double-scrape: kubernetes-pods job was scraping traefik
  pods again (43k duplicate series). Added namespace drop rule.
- drop unused cadvisor metrics: container_fs_*, container_blkio_*,
  container_pressure_*, container_spec_*, and misc (30k series)
- drop more apiserver histogram buckets: watch_list, watch_cache,
  response_sizes, watch_events, admission_controller, workqueue (11k)
- drop unused kube-state-metrics: replicaset_*, pod_tolerations,
  pod_labels, endpoint_*, service_*, configmap_*, etc (53k series)

Post-relabel samples: 332k → 142k (-57%)
Ingestion rate: 5,480 → 3,239 samples/sec (-41%)

4b3851829b feat: organize Grafana dashboards into folders
Enable sidecar folderAnnotation + foldersFromFilesStructure to group
26 dashboards into 5 managed folders:

- Cluster (6): k8s health, API server, nodes, pods, kube-state-metrics
- Networking (6): CoreDNS, Technitium, Headscale, ingress, network traffic
- Hardware (5): node-exporter, proxmox, iDRAC, UPS, NVIDIA GPU
- Operations (4): backup health, registry, audit logs, Loki
- Applications (2): realestate-crawler, qBittorrent

Dashboard-to-folder mapping defined in grafana.tf locals block.
External stacks (headscale, technitium) annotated individually.

725fefe565 fix: add Headscale monitoring, alerts, and pin UI image
- Add 4 Prometheus alerts: HeadscaleDown (critical), NoOnlineNodes,
  HighHTTPLatency, HighErrorRate
- Add Grafana dashboard with node count, map responses, HTTP latency,
  nodestore operations, and memory panels
- Pin headscale-ui to digest sha256:015f5ba0... (was :latest)
- Set disable_check_updates: true to skip GitHub check on startup
- Uptime Kuma monitor already existed (id=19, 300s interval)

f4ff654a69 perf: optimize Headscale for connectivity and latency
- Remove viktorbarzin.me from split DNS (same IPs as public DNS,
  was adding unnecessary tunnel overhead for every DNS query)
- Narrow reverse DNS split scope from 10.0.0.0/8 → 10.0.20.0/24
  and 10.0.10.0/24 only; 192.168.0.0/16 → 192.168.1.0/24 only
- Add extra_records for key internal services (technitium, k8s-master)
  for instant MagicDNS resolution without tunnel roundtrip
- Replace full Tailscale DERP map (29 regions) with curated set:
  home + 8 European + 5 global fallback DERPs (14 total)
- Add custom derp.yaml to ConfigMap, sourced from Vault

Port 80 DERP dropped — Traefik's global HTTP→HTTPS redirect
prevents non-TLS DERP upgrades on the web entrypoint.

8a5a53a832 fix alerts and reduce Prometheus disk write rate
- linkwarden: add Reloader match annotation to DB secret so pods
  auto-restart on Vault credential rotation (was causing 100% 5xx)
- authentik: increase memory limits (server 1Gi→1.5Gi, worker 896Mi→1Gi)
  to prevent OOM kills
- prometheus: drop 113k high-cardinality series to reduce HDD write rate
  from ~8.8 to ~6.0 MB/s (31% reduction):
  - drop all traefik/apiserver/etcd histogram bucket metrics
  - drop goflow2_flow_process_nf_templates_total (9.3k series)
  - drop container_tasks_state and container_memory_failures_total
  - rewrite HighServiceLatency alert to use avg latency (_sum/_count)
  - update cluster_health dashboard to match
- raise KubeletRuntimeOperationsLatency threshold from 30s to 60s

7e0b0d9362 fix: headscale VPN setup hardening
- Add SQLite backup CronJob (every 6h to NFS for cloud sync pickup)
- Move headscale-ui secrets (COOKIE_SECRET, ROOT_API_KEY) from hardcoded
  values to Vault-managed secrets
- Add DERP IPv6 address (2001:470:6e:43d::2) for IPv6-capable clients
- Clean up stale test nodes, duplicate users, rename "localhost" nodes

Also updated headscale_config in Vault to include DERP ipv6 field
and headscale_ui_cookie_secret/headscale_ui_api_key secrets.

(10.0.20.200:53).

PVs with >1TiB capacity (always NFS mounts; iSCSI PVCs are 10-50Gi).
