## Deployment Details

### Configuration Changes Deployed

For all nodes:
- ✅ Removed 11 deprecated options
- ✅ Logging optimized (WARN for validators/RPC, INFO for sentries)
- ✅ CORS hardened (specific origins for core RPC)
- ✅ Empty comments cleaned
- ✅ All configs validated before deployment

### Backup Status

All existing configurations were backed up with timestamps:
- Backup format: `/etc/besu/config-*.toml.backup.YYYYMMDD_HHMMSS`
- All backups created successfully before deployment

---

## Post-Deployment Verification

### Service Status

All services restarted successfully:
- ✅ All validator services: Active
- ✅ All sentry services: Active
- ✅ RPC service (2101): Active

### Configuration Verification

- ✅ All configs deployed and validated
- ✅ No deprecated options detected
- ✅ Logging levels correct:
  - Validators: WARN
  - Sentries: INFO
  - RPC: WARN

### Error Checking

Run verification:
```bash
./scripts/verify-post-deployment.sh
```

---

## Monitoring Plan

### Immediate (0-1 hour)

- [ ] Verify all services are active
- [ ] Check for configuration errors in logs
- [ ] Verify logging levels are correct
- [ ] Test RPC endpoints (if applicable)

### Short-term (1-6 hours)

- [ ] Monitor service status
- [ ] Check for configuration-related errors
- [ ] Verify network connectivity
- [ ] Test consensus participation (validators)
- [ ] Test archive queries (sentries)

### Medium-term (6-48 hours)

- [ ] Monitor resource usage (memory, CPU, disk)
- [ ] Check peer connections
- [ ] Verify sync status
- [ ] Monitor for performance issues

---

## Verification Commands

### Check Service Status

```bash
# Validators
for vmid in 1000 1001 1002 1003 1004; do
    pct exec $vmid -- systemctl status besu-validator.service
done

# Sentries
for vmid in 1500 1501 1502 1503; do
    pct exec $vmid -- systemctl status besu-sentry.service
done

# RPC
pct exec 2101 -- systemctl status besu-rpc.service
```

### Check Logging Levels

```bash
# Validators (should be WARN)
pct exec 1000 -- grep "^logging" /etc/besu/config-validator.toml

# Sentries (should be INFO)
pct exec 1500 -- grep "^logging" /etc/besu/config-sentry.toml

# RPC (should be WARN)
pct exec 2101 -- grep "^logging" /etc/besu/config-rpc-core.toml
```

### Check for Errors

```bash
# Check recent logs for errors
pct exec 1000 -- journalctl -u besu-validator.service --since "1 hour ago" | grep -i "error\|unknown option"

pct exec 1500 -- journalctl -u besu-sentry.service --since "1 hour ago" | grep -i "error\|unknown option"

pct exec 2101 -- journalctl -u besu-rpc.service --since "1 hour ago" | grep -i "error\|unknown option"
```

---

## Skipped Nodes

The following RPC nodes were skipped (not running):
- VMID 2500-2508: Stopped containers (will deploy when started)

**Note**: These nodes will be deployed automatically when started and deployment script is run again.

---

## Rollback Procedure

If issues are detected, rollback using backups:

```bash
# For each node, restore from backup
# Example for validator 1000:
pct exec 1000 -- cp /etc/besu/config-validator.toml.backup.YYYYMMDD_HHMMSS /etc/besu/config-validator.toml
pct exec 1000 -- systemctl restart besu-validator.service
```

**Backup locations**: All backups are on each node at `/etc/besu/config-*.toml.backup.*`

---

## Deployment Logs

Deployment logs saved:
- Deployment log: `/tmp/besu-deployment.log`
- Verification log: `/tmp/post-deployment-verification.log`
