### Phase 6: Witness Protocol
**Priority: LOW** | **Estimated Effort: 4-5 weeks**

Witness protocol enables rapid failover notification for clustered file servers.

#### 6.1 Core Witness Infrastructure
```
Package: jcifs.internal.witness
├── WitnessClient.java           - Witness client implementation

    .setSize(10)
    .execute()
    .getResponse();
```

## Troubleshooting

### Common Issues

**Index Creation Fails**
- Verify OpenSearch cluster is accessible
- Check index permissions and mappings
- Ensure sufficient cluster resources

**Suggestions Not Appearing**
- Confirm documents are indexed: `suggester.refresh()`
- Check query formatting and filters
- Verify analyzer configurations

declaratively. It handles versioning, multiple simultaneous rollouts,
aggregating status across all pods, maintaining application availability, and
rollback.
  * <strong>Automated cluster management: </strong>
     * Kubernetes clusters can now span zones within a cloud provider. Pods from a
service will be automatically spread across zones, enabling applications to
tolerate zone failure.

## 1. Overview

The SMB Witness Protocol enables rapid notification of resource changes in a clustered file server environment. It provides fast failover capabilities by allowing clients to register for notifications about server node availability, share movement, and other critical cluster events.
