Overview + +PinnacleMM is a stateful, singleton market-making system deployed as a Kubernetes StatefulSet with exactly one replica. Its disaster recovery (DR) capabilities are built around three pillars: + +- **Write-ahead journal** -- every state mutation is appended to a durable journal before being applied. On restart the journal is replayed to reconstruct the last known state. +- **Periodic snapshots** -- the `PersistenceManager` writes full-state snapshots at a configurable interval (default 15 min) and retains the last N snapshots (default 5). Snapshots allow fast recovery without replaying the entire journal. +- **Atomic risk-state files** -- the `DisasterRecovery` module writes risk and strategy state to disk via atomic rename, so a crash can never leave a half-written state file. + +All persistent data lives on a 10 Gi PVC mounted at `/data/pinnaclemm`. Logs are written to `/var/log/pinnaclemm`. + +--- + +## 2. Crash Recovery (Automatic) + +PinnacleMM recovers automatically when the pod restarts after a crash. No operator action is needed unless recovery fails. + +**What happens on startup:** + +1. `PersistenceManager::recoverState()` is called. +2. It loads the most recent valid snapshot from `/data/pinnaclemm//snapshots/`. +3. It replays all journal entries written after the snapshot's sequence number from `/data/pinnaclemm//journal/`. +4. Recovered order books are made available via `getRecoveredOrderBooks()`. +5. `DisasterRecovery` restores risk state and strategy state from their atomic files. +6. The strategy resumes quoting. + +**Recovery status codes returned by `recoverState()`:** + +| Status | Meaning | +|---|---| +| `Success` | State fully recovered from snapshot + journal | +| `CleanStart` | No prior data found; system starts fresh | +| `Failed` | Recovery could not complete; see logs | + +**If recovery fails:** + +1. Check pod logs: `kubectl logs -n pinnaclemm pinnaclemm-0`. +2. Look for `PersistenceManager` or `DisasterRecovery` error messages. +3. If the journal is corrupt, follow Section 4 (Corrupt Journal Recovery). +4. If the PVC is missing or inaccessible, verify the StorageClass and PVC status: `kubectl get pvc -n pinnaclemm`. + +--- + +## 3. Exchange Disconnect Recovery + +When the exchange WebSocket or FIX connection drops, PinnacleMM performs automatic reconnection. + +**Automatic behavior:** + +1. The exchange connector detects the disconnect. +2. Open orders are assumed stale and are cancelled on reconnection. +3. The connector retries with exponential backoff. +4. On reconnection, a full position reconciliation is triggered: the system queries the exchange for current positions and open orders. +5. Any discrepancies between local state and exchange state are logged and corrected. + +**Manual intervention (if auto-reconnect fails after extended outage):** + +1. Verify network connectivity from the pod: + ```bash + kubectl exec -n pinnaclemm pinnaclemm-0 -- curl -s https://api.exchange.com/status + ``` +2. Check exchange status pages for planned maintenance. +3. If the exchange is up but the connector cannot reconnect, restart the pod: + ```bash + kubectl delete pod -n pinnaclemm pinnaclemm-0 + ``` + The StatefulSet will recreate the pod and crash recovery will restore state. + +--- + +## 4. Corrupt Journal Recovery + +If the journal file is truncated or corrupted (e.g., due to storage failure), PinnacleMM falls back to the most recent valid snapshot. + +**Symptoms:** +- Logs contain `Journal replay failed` or `CRC mismatch` errors. +- `recoverState()` returns `Failed`. + +**Procedure:** + +1. Stop the pod to prevent further writes: + ```bash + kubectl scale statefulset -n pinnaclemm pinnaclemm --replicas=0 + ``` +2. Attach to the PVC from a debug pod: + ```bash + kubectl run -n pinnaclemm debug --rm -it --image=busybox \ + --overrides='{"spec":{"containers":[{"name":"debug","volumeMounts":[{"name":"pinnaclemm-data","mountPath":"/data/pinnaclemm"}]}],"volumes":[{"name":"pinnaclemm-data","persistentVolumeClaim":{"claimName":"pinnaclemm-data-pinnaclemm-0"}}]}}' + ``` +3. Back up the corrupt journal: + ```bash + cp -r /data/pinnaclemm//journal /data/pinnaclemm//journal.corrupt.bak + ``` +4. Delete the corrupt journal files: + ```bash + rm /data/pinnaclemm//journal/*.journal + ``` +5. Verify that snapshots are intact: + ```bash + ls -la /data/pinnaclemm//snapshots/ + ``` +6. Exit the debug pod and scale back up: + ```bash + kubectl scale statefulset -n pinnaclemm pinnaclemm --replicas=1 + ``` +7. On startup, `recoverState()` will load from the latest snapshot with no journal to replay. The system resumes from the snapshot point. Any state changes between the last snapshot and the crash are lost. + +--- + +## 5. Manual Position Adjustment + +If the system's internal position tracking drifts from the exchange's actual positions (e.g., after a partial recovery or manual exchange-side trade), you may need to reconcile manually. + +**Procedure:** + +1. Query current positions from the exchange via the REST API: + ```bash + kubectl exec -n pinnaclemm pinnaclemm-0 -- curl -s http://localhost:8081/api/positions + ``` +2. Compare with exchange-reported positions (check the exchange dashboard or API directly). +3. If there is a discrepancy, trigger a forced reconciliation: + ```bash + kubectl exec -n pinnaclemm pinnaclemm-0 -- curl -X POST http://localhost:8081/api/reconcile + ``` +4. Verify the updated positions: + ```bash + kubectl exec -n pinnaclemm pinnaclemm-0 -- curl -s http://localhost:8081/api/positions + ``` +5. Check logs for reconciliation results: + ```bash + kubectl logs -n pinnaclemm pinnaclemm-0 --tail=50 + ``` + +--- + +## 6. Backup and Restore Procedures + +### 6.1 Create a Backup + +Create an on-demand backup of the entire data directory: + +```bash +# Create a timestamped backup tarball from the running pod +kubectl exec -n pinnaclemm pinnaclemm-0 -- \ + tar czf /tmp/pinnaclemm-backup-$(date +%Y%m%d-%H%M%S).tar.gz \ + -C /data/pinnaclemm . + +# Copy the backup to your local machine +kubectl cp pinnaclemm/pinnaclemm-0:/tmp/pinnaclemm-backup-*.tar.gz ./backups/ +``` + +### 6.2 List Available Backups + +List snapshots available on the PVC: + +```bash +kubectl exec -n pinnaclemm pinnaclemm-0 -- \ + find /data/pinnaclemm -name '*.snapshot' -type f | sort +``` + +List local backup tarballs: + +```bash +ls -lht ./backups/pinnaclemm-backup-*.tar.gz +``` + +### 6.3 Restore from Backup + +1.

Exit the debug pod and scale back up: + ```bash + kubectl scale statefulset -n pinnaclemm pinnaclemm --replicas=1 + ``` +6. Verify recovery in logs: + ```bash + kubectl logs -n pinnaclemm pinnaclemm-0 -f + ``` + +--- + +## 7. Split-Brain Prevention + +PinnacleMM is deployed as a StatefulSet with exactly **one replica**. This is a deliberate design choice: + +- A market-making system must not have two instances simultaneously placing orders on the same exchange account. Duplicate quoting would cause self-trading, doubled position risk, and order-ID collisions. +- The `PodDisruptionBudget` (minAvailable: 1) prevents Kubernetes from evicting the sole replica during voluntary disruptions (node drains, cluster upgrades). +- The StatefulSet guarantees at-most-one semantics: Kubernetes will not start a replacement pod until the old pod's volume is fully released. + +**Never scale the StatefulSet above 1 replica** unless the application has been explicitly modified to support leader election. + +--- + +## 8. Risk State Recovery + +Risk state is automatically restored on startup by the `DisasterRecovery` module. + +**What is recovered:** + +- Current P&L, drawdown tracking, and daily loss counters. +- Position limits and exposure tracking. +- VaR model state (return history and current VaR estimate). +- Circuit breaker state (trip counts, cooldown timers). +- Alert history. +- Strategy-specific state (inventory, last quote prices, ML model parameters). + +**How it works:** + +1. `DisasterRecovery::saveRiskState()` writes risk and strategy state to atomic files on every state change (write to temp file, then `rename()`). +2. On startup, `DisasterRecovery` reads these files and restores the full risk context. +3. If the risk state files are missing or corrupt, the system starts with default risk limits from the configuration and logs a warning. + +**Manual verification after recovery:** + +```bash +kubectl exec -n pinnaclemm pinnaclemm-0 -- \ + curl -s http://localhost:8081/api/risk/status | python3 -m json.tool +``` + +--- + +## 9. Circuit Breaker Recovery + +The circuit breaker protects the system from runaway losses during extreme market conditions. + +**Circuit breaker triggers (from configuration):** + +| Trigger | Threshold | +|---|---| +| 1-minute price move | 2.0% | +| 5-minute price move | 5.0% | +| Spread widening | 3x normal | +| Volume spike | 5x normal | +| Execution latency | > 10 ms | + +**Recovery behavior:** + +1. When the circuit breaker trips, all quoting stops immediately and open orders are cancelled. +2. After the cooldown period (default 30 seconds), the circuit breaker enters a **half-open** state. +3. During the half-open test window (default 10 seconds), the system places limited test quotes. +4. If the test period completes without re-triggering, the circuit breaker fully resets and normal quoting resumes. +5. If a trigger fires again during the half-open window, the circuit breaker re-trips and the cooldown restarts. + +**Manual override (use with caution):** + +```bash +# Force-reset the circuit breaker +kubectl exec -n pinnaclemm pinnaclemm-0 -- \ + curl -X POST http://localhost:8081/api/risk/circuit-breaker/reset +``` + +After a pod restart, the circuit breaker state is restored from the risk state file. If the system was mid-cooldown at the time of the crash, the cooldown timer restarts from the beginning. + +--- + +## 10.
