ISSUE RESOLVED:
- Root cause: Loki's 15GB iSCSI PVC was completely full
- Symptom: 'no space left on device' errors during TSDB operations
- Impact: Loki service completely down, logging unavailable
- Side effects: Contributed to node2 containerd corruption incident
SOLUTION APPLIED:
- Expanded PVC storage: 15Gi → 50Gi via direct kubectl patch
- Triggered pod restart to complete filesystem resize
- Verified successful expansion and service recovery
CURRENT STATUS:
✅ PVC: 50Gi capacity (iscsi-truenas storage class)
✅ Loki StatefulSet: 1/1 ready
✅ Loki Pod: 2/2 containers running
✅ Service: Successfully processing log streams
✅ No storage errors in recent logs
TERRAFORM ALIGNED:
- Updated loki.yaml persistence.size to match actual PVC
- Infrastructure code now reflects deployed state
[ci skip] - Emergency fix applied locally first due to service outage
- MaxRequestWorkers 25→50: too few workers caused ALL workers to block
on SQLite locks, making liveness probes fail even faster (131 restarts
vs 50 before). 50 is a compromise — enough workers for probes.
- Excluded nextcloud from HighServiceErrorRate alert (chronic SQLite issue)
- MySQL migration attempted but hit: GR error 3100 (fixed with GIPK),
emoji in calendar/filecache (stripped), SQLite corruption (pre-existing
from crash-looping). Migration rolled back, Nextcloud restored to SQLite.
- JobFailed: only alert on jobs started within the last hour, so stale
failed CronJob runs don't keep firing after subsequent runs succeed
- Mail server alert: renamed to MailServerDown, now targets the specific
mailserver deployment instead of all deployments in the namespace
(was falsely triggering on roundcubemail going down)
- Updated inhibition rule to use new MailServerDown alert name
Add Kubernetes ingress annotations for Homepage auto-discovery across
~88 services organized into 11 groups. Enable serviceAccount for RBAC,
configure group layouts, and add Grafana/Frigate/Speedtest widgets.
Phase 5 — CI pipelines:
- default.yml: add SOPS decrypt in prepare step, change git add . to
specific paths (stacks/ state/ .woodpecker/), cleanup on success+failure
- renew-tls.yml: change git add . to git add secrets/ state/
Phase 6 — sensitive=true:
- Add sensitive = true to 256 variable declarations across 149 stack files
- Prevents secret values from appearing in terraform plan output
- Does NOT modify shared modules (ingress_factory, nfs_volume) to avoid
breaking module interface contracts
Note: CI pipeline SOPS decryption requires sops_age_key Woodpecker secret
to be created before the pipeline will work with SOPS. Until then, the old
terraform.tfvars path continues to function.
Critical fix: StorageClass mountOptions only apply during dynamic
provisioning. Our static PVs (created by Terraform) were missing
mount_options, so all NFS mounts defaulted to hard,timeo=600 —
the exact stale mount behavior we were trying to eliminate.
Adds mount_options directly to the nfs_volume module PV spec and
to the monitoring PVs (prometheus, loki, alertmanager).
Requires re-applying all stacks to propagate to existing PVs.
- cache_from/cache_to must be plain strings, not YAML lists — the
plugin-docker-buildx treats them as single string values and the
Woodpecker settings layer was splitting comma-separated list items
into separate --cache-from flags (type=registry and ref=... separately)
- caretta.tf: replace deprecated set{} blocks with values=[yamlencode()]
to fix Terraform plan error with newer Helm provider
- Add missing nvidia.com/gpu toleration to ollama and yt-highlights deployments
- Add node_selector gpu=true to ollama deployment
- Pass nfs_server variable through to actualbudget factory modules
- Fix AuthentikDown alert to match actual deployment name (goauthentik-server)
Add "Per-Path Latency Breakdown" table with p50/p95/p99 and request rate
per endpoint. Fix bar gauge position to sit next to timeseries. Add sort
transformation to "Top Offenders (Avg Duration)" panel.
Move API Performance and Per-Endpoint Latency to the top.
Move Scraping Overview, Scraping Activity, and Throttling & Errors
to the bottom. Keeps the most operationally relevant panels visible
first.
- Add gpu=true label to Terraform (nvidia null_resource alongside taint)
- Improve API server OIDC config to detect value changes, not just flag presence
- Add policy_hash trigger to audit-policy so rule changes auto-reapply
- Enable prometheus-node-exporter sub-chart, delete unused Ansible playbook
- Document full node rebuild procedure in CLAUDE.md
- Save Talos Linux migration evaluation for future reference
Move all 88 service modules (66 individual + 22 platform) from
modules/kubernetes/<service>/ into their corresponding stack directories:
- Service stacks: stacks/<service>/module/
- Platform stack: stacks/platform/modules/<service>/
This collocates module source code with its Terragrunt definition.
Only shared utility modules remain in modules/kubernetes/:
ingress_factory, setup_tls_secret, dockerhub_secret, oauth-proxy.
All cross-references to shared modules updated to use correct
relative paths. Verified with terragrunt run --all -- plan:
0 adds, 0 destroys across all 68 stacks.
