## [2026-07-25] fix | Loki 500 Error + CNPG Leader Election + Stale Pods Cleanup
- **Loki HTTP 500**: `replication_factor: 3` in hash ring with only 1 SingleBinary instance → "too many unhealthy instances in the ring". Chart v6.42.0 ignores `loki.common.replication_factor` — correct path is `loki.commonConfig.replication_factor`. Fix: commit `cb70d36`
- **Memcached caches disabled**: `chunksCache.enabled: false`, `resultsCache.enabled: false` (SingleBinary doesn't need them). Commit `f8852e8`
- **Fluent Bit**: cascading failure from Loki 500s — fixed automatically once Loki accepted pushes
- **CNPG 28+129 restarts**: Leader election lease renewal failed during API server latency spikes (Ceph recovery I/O). Default 15s/10s too short. Fix: `--leader-lease-duration=60 --leader-renew-deadline=40` via `additionalArgs`. Commit `6ed4a53`
- **17 stale node-debugger pods** deleted from default namespace
- **OSDs 0+2 destroyed+purged** (proxmox2, SSDs with 92% wear + slow ops). CRUSH host proxmox2 removed. 13 OSDs remaining on 8 hosts.
- Wiki updated: ceph-cluster.md, loki-fluentbit.md

## [2026-07-25] fix | Memory Sync Broken — HTTP→HTTPS + Ceph Duplicate
- Git push failed: remote URL used `http://` but Gitea redirects to `https://` — git doesn't follow auth redirects
- Token itself was valid (same as ArgoCD `argocd-repo-credentials`), just wrong protocol
- Fixed: `git remote set-url` to `https://`
- Eliminated duplicate: `systems/ceph.md` (82 lines, no frontmatter) merged into `systems/ceph-cluster.md` (canonical, referenced in index.md)
- Fixed sync script: removed `--allow-empty` flag, improved change detection

## [2026-07-24] fix | Velero CSI Volume Snapshots Three-Layer Fix
- Velero backups PartiallyFailed for 121 days — all PVCs skipped
- Fix 1: Created VolumeSnapshotClass `ceph-rbd-snapclass` (rbd.csi.ceph.com)
- Fix 2: Migrated ArgoCD repoURLs from dead Gitea (10.0.30.105) to new (ssh://git@10.0.30.202:22)
  - Gitea SSH user is `git` not `gitea`; git.schoen.codes → Traefik (10.0.30.203), SSH on 10.0.30.202
  - New SSH deploy key generated, added to Gitea repo
- Fix 3: `features: EnableCSI` must be under `configuration:` in Velero Helm values (not top-level)
  - Must be string, not array — array form breaks Helm template
- Verified: test backup created VolumeSnapshot + VolumeSnapshotContent, uploaded to S3 ✅

## [2026-07-24] fix | VFIO Module Loading Race Condition RCA + Fix
- RCA: GPU passthrough failed on ms-a2-1 due to missing modprobe config (NOT kernel version)
- Root cause: Missing `softdep amdgpu pre: vfio-pci` + incomplete DRM blacklist → race condition (302s vs 2.4s bind time)
- Fix applied to ms-a2-1: Added `blacklist drm`, `blacklist drm_kms_helper`, `softdep amdgpu pre: vfio-pci`, rebuilt initramfs
- Verification pending (reboot required, 4 VMs + OSD 13 on ms-a2-1)
- Solution doc: docs/solutions/bug-fixes/2026-07-24-vfio-pci-module-loading-race-condition.md
- Also documented: K8s persistent storage architecture (all PVCs on Ceph RBD, 3x replication)
- Solution doc: docs/solutions/architecture/2026-07-24-k8s-persistent-storage-ceph-rbd.md

## [2026-07-24] fix | worker-05 GPU Passthrough — Move to ms-a2-2
- Problem: worker-05 (VM 102) on ms-a2-1 had kernel BUG with 1002:13c0 GPU — /dev/dri/renderD128 missing
- ms-a2-1 and ms-a2-2 have identical hardware (AMD Ryzen 9 9955HX, GPU 1002:13c0)
- Solution: Moved VM 102 from ms-a2-1 to ms-a2-2 (offline migration, Ceph RBD shared storage)
- Result: renderD128 ✅ visible in guest, amdgpu driver loaded, all pods running
- IaC: main.tf cleaned up — single unified rke2_worker block, worker-05 node=ms-a2-2, worker-06 removed
- PCI mapping: amd-gpu now includes n5pro + ms-a2-1 + ms-a2-2
- Commit: 21bd335
- Also: ms-a2-2 upgraded PVE 9.1.1→9.2.5, kernel 7.0.14-6-pve, VFIO persistent after reboot, HA integrated

## [2026-07-24] init | ms-a2-2 Node Initialization
- New Proxmox node ms-a2-2 (10.0.20.93, nodeid 1) joined cluster
- Hardware: AMD Ryzen 9 9955HX (32 threads), 91GB RAM, 1.8TB NVMe
- GPU: AMD Radeon 1002:13c0 (identical to ms-a2-1) — VFIO passthrough configured
- PCI mapping: amd-gpu-ms-a2-2 created, added to generic amd-gpu mapping
- Ceph OSD 14: created on nvme0n1 (1.8TB SSD), class ssd, weight 1.82
- Fluent-bit: installed + configured (hostname adapted to ms-a2-2)
- APT sources: fixed from enterprise to no-subscription (ceph + pve)
- LLM Wiki: ip-map.md, ceph.md updated; AGENTS.md updated (9 nodes)
- Note: PVE 9.1.1 on ms-a2-2 (rest of cluster is 9.2.3) — upgrade pending

## [2026-07-24] cleanup | proxmox1 Permanent Removal + Ceph PG Fixes
- Removed proxmox1 from Ceph CRUSH (empty host bucket, weight 0)
- Also removed stale empty buckets: proxmox, px-tmp20
- Updated corosync.conf: removed proxmox1 node entry, config_version 14→15, expected_votes 9→8
- Removed stale /etc/pve/nodes/{proxmox1,proxmox,pve,px-tmp20}
- Updated IaC: proxmox_api_url 10.0.20.10→10.0.20.91, template_node proxmox1→n5pro, target_nodes list updated
- Updated AGENTS.md topology (9→8 nodes), LLM Wiki ip-map.md + ceph.md
- Commit: 469d29d
- Additional: Manual pg-upmap for stuck PGs 5.13→[1,6,7], 6.6c→[11,8,7] — all clean+remapped eliminated

## [2026-07-24] fix | Ceph Remapped PGs — Weight Imbalance + pg_num Mismatch
- RCA: 11 active+clean+remapped PGs caused by CRUSH placement failure
- Root cause 1: Pool 6 (hdd_disk) pg_num=120 ≠ pgp_num=112 (autoscaler mid-merge)
- Root cause 2: Extreme HDD host weight imbalance (n5pro=10TB vs proxmox6=0.3TB)
- Fix: Equalized pg_num→112, set nopgchange=true, reweighted osd.7 0.80→1.0
- Result: 9/11 PGs recovering (backfilling at 36MiB/s), 2 cosmetic clean+remapped remain
- Created systems/ceph.md with full OSD/pool/CRUSH documentation

## [2026-07-24] update | Gitea Actions K8s Runner Bug + DinD Pitfalls

- Updated systems/gitea.md with known issue, DinD pitfalls, runner management via DB
- Solution doc: docs/solutions/bug-fixes/2026-07-24-gitea-actions-k8s-runner-task-assignment-bug.md
