    * In order to safely upgrade an existing Kubernetes cluster without interruption of volume attach/detach logic:
        * First upgrade the master to Kubernetes v1.3.
            * This will start the new attach/detach controller.

- Add lease break handling in `SmbTransport`

### Phase 2: Persistent Handles
**Priority: HIGH** | **Estimated Effort: 4-5 weeks**

Persistent handles allow connections to survive network interruptions and server failovers.

#### 2.1 Core Persistent Handle Infrastructure
```
Package: jcifs.internal.smb2.persistent
├── PersistentHandleContext.java     - Persistent handle create context

            crawlingInfoHelper.putToInfoMap(key, dateFormat.format(new Date()));
        }
    }

    /**
     * Waits for a crawler thread to complete execution.
     * This method handles interruptions gracefully and logs when a crawler process is interrupted.
     *
     * @param crawlerThread the thread to wait for; null threads are ignored
     */
    private void joinCrawlerThread(final Thread crawlerThread) {

 *  Fix: Recover gracefully when worker threads are interrupted. When we introduced fast fallback in
    OkHttp 5.0, we started using background threads while connecting. Sadly that code didn't handle
    interruptions well. This is now fixed.

 *  Upgrade: [Kotlin 2.2.20][kotlin_2_2_20].
 *  Upgrade: [Okio 3.16.0][okio_3_16_0].
