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
