Postgres PVC hit 100% → crash-looped → GitLab webservice couldn't verify SSH keys → all git operations failed. Root cause: 10Gi PVC outgrown by GitLab database. Fixes applied: - Expand postgres PVC 10Gi → 20Gi - Expand minio PVC 100Gi → 150Gi (was 81.8% full) - Expand prometheus PVC 2Gi → 10Gi, retentionSize 1500MB → 8GB - Scale gitlab-webservice to 2 replicas for HA - Add PVC autoscaler CronJob (every 15min, auto-expand at 85%) - Add daily postgres backup CronJob (pg_dump → MinIO, 7d + 4w retention) - Add PrometheusRule storage alerts (75% warning, 90% critical) - Add network policies for maintenance job egress Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
