Deleted the 6 NFS PVs orphaned by the Phase 2 rolling and removed
their /srv/nfs/<dir> subtrees on the PVE host (~1.5 GB; vault-2 audit
log was 1.4 GB on its own). Cluster-wide Released-PV sweep on the
proxmox-lvm/encrypted side stays out of scope.
All 3 vault voters now on proxmox-lvm-encrypted (vault-0 16:18, vault-1
+ vault-2 today). The NFS fsync incompatibility identified in the
2026-04-22 raft-leader-deadlock post-mortem is no longer reachable —
raft consensus log + audit log live on LUKS2 block storage with real
fsync semantics.
Cluster-wide consumers of the inline kubernetes_storage_class.nfs_proxmox
dropped to zero after the rolling, so the resource is removed from
infra/stacks/vault/main.tf. Released NFS PVs (6) remain in the cluster
and will be reclaimed in Phase 3 cleanup.
Lesson learned (recorded in plan): pvc-protection finalizer races the
StatefulSet controller — pod recreates on the OLD PVCs unless the
finalizer is patched out before pod delete. Force-finalize technique
applied to vault-1 + vault-2 successfully.
Closes: code-gy7h
Phase 2 of the NFS-hostile migration: data + audit storageClass on
the vault helm release switches from nfs-proxmox to
proxmox-lvm-encrypted, then per-pod rolling swap (24h soak between).
vault-0 swap done. vault-1 + vault-2 still on NFS — the rolling part
is what makes this safe (raft quorum maintained by 2 healthy pods
while one is replaced).
Also restores chart-default pod securityContext fields. The previous
`statefulSet.securityContext.pod = {fsGroupChangePolicy = "..."}`
block REPLACED (not merged) the chart's defaults — fsGroup,
runAsGroup, runAsUser, runAsNonRoot were all silently dropped. NFS
exports were permissive enough to mask the missing fsGroup; ext4 LV
volume root is root:root and the vault user (UID 100) couldn't open
vault.db, CrashLoopBackOff. Fix: provide all five fields explicitly,
survives future chart bumps. vault-1 and vault-2 retained their
correct securityContext from when their pod specs were written to
etcd, before the partial customization landed — the bug only surfaces
when a pod is recreated.
Pre-flight raft snapshot saved at /tmp/vault-pre-migration-*.snap
(recovery anchor).

Live PG data moves to a 10Gi LUKS-encrypted RWO PVC. WAL fsync per
commit on NFS contributed to the 2026-04-22 NFS writeback storm
(2h43m recovery, 3 of 4 nodes hard-reset). Backups remain on NFS
(append-only, NFS-tolerant).
The init container that writes postgresql.override.conf is now gated
on PG_VERSION presence — on a fresh PVC the file would otherwise make
initdb refuse the non-empty PGDATA. First boot skips the override and
initdb's cleanly; second boot (after a forced restart) writes the
override so vchord/vectors/pg_prewarm load before the dump restore.
Idempotent on initialised PVCs.
Migration executed: pg_dumpall (1.9GB) → restore on encrypted PVC →
REINDEX clip_index/face_index → 111,843 assets verified, external
HTTP 200, all 10 extensions present (vector minor 0.8.0→0.8.1 only).
LV created on PVE host, picked up by lvm-pvc-snapshot.
See docs/plans/2026-04-25-nfs-hostile-migration-{design,plan}.md.
Phase 2 (Vault Raft) follows under code-gy7h.
Closes: code-ahr7

Inbound:
- Direct MX to mail.viktorbarzin.me (ForwardEmail relay attempted and abandoned)
- Dedicated MetalLB IP 10.0.20.202 with ETP: Local for CrowdSec real-IP detection
- Removed Cloudflare Email Routing (can't store-and-forward)
- Fixed dual SPF violation, hardened to -all
- Added MTA-STS, TLSRPT, imported Rspamd DKIM into Terraform
- Removed dead BIND zones from config.tfvars (199 lines)
Outbound:
- Migrated from Mailgun (100/day) to Brevo (300/day free)
- Added Brevo DKIM CNAMEs and verification TXT
Monitoring:
- Probe frequency: 30m → 20m, alert thresholds adjusted to 60m
- Enabled Dovecot exporter scraping (port 9166)
- Added external SMTP monitor on public IP
Documentation:
- New docs/architecture/mailserver.md with full architecture
- New docs/architecture/mailserver-visual.html visualization
- Updated monitoring.md, CLAUDE.md, historical plan docs
- 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/
Major milestone - shared PostgreSQL moved from NFS to CloudNativePG:
- CNPG cluster (pg-cluster) running in dbaas namespace on local-path storage
- PostGIS image (ghcr.io/cloudnative-pg/postgis:16) for dawarich compatibility
- All 20 databases and 19 roles restored from pg_dumpall backup
- postgresql.dbaas Service patched to point at CNPG primary
- Old PG deployment scaled to 0 (NFS data intact for rollback)
- All 12+ dependent services verified running:
authentik, n8n, dawarich, tandoor, linkwarden, netbox, woodpecker,
rybbit, affine, health, resume, trading-bot, atuin
- Authentik PgBouncer working through the switched endpoint
TODO: codify CNPG cluster in Terraform, add 2nd replica, update backup CronJob
Key changes from v1:
- Drop 3-instance replication → 2-instance CNPG, single Redis/MySQL
- Remove Headscale from PG migration (project discourages it)
- Remove MeshCentral from PG migration (NeDB, not SQLite)
- Replace Redis Sentinel with single redis:7 on local disk (modules unused)
- Add RAM overcommit warning and mitigation
- Add explicit single-host limitation acknowledgment
- Add per-component rollback plans
- Fix backup strategy (CNPG can't archive WAL to NFS natively)
- Reorder migration: low-risk services first, authentik last
- Add research gate before each service migration
- 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
Delete 20 orphaned module directories and 3 stray files from
modules/kubernetes/ that are no longer referenced by any stack.
Remove 7 root-level legacy files including the empty tfstate,
27MB terraform zip, commented-out main.tf, and migration notes.
Clean up commented-out dockerhub_secret and oauth-proxy references
in blog, travel_blog, and city-guesser stacks. Remove stale
frigate config.yaml entry from .gitignore. Remove ephemeral
docs/plans/ directory.
