Scenario
I have set up a QNAP high-availability (HA) cluster and want to confirm it’s working correctly. What are the recommended ways to test its functionality?
Procedure
To confirm your HA cluster is working correctly, perform the following tests.
Tip
- Always perform a full data backup before initiating any HA-related tests to prevent data loss.
- If your HA cluster is operating in a production environment, avoid simulating power or network failures directly. Perform these tests in a non-production environment if possible.
- During testing, closely monitor event logs and status changes in High Availability Manager.
Test 1: Manual switchover
This test verifies that the switchover mechanism is working properly.
- Go to High Availability Manager > Cluster.
- Confirm the statuses of the current active and passive nodes.
- Click Manage, and then select Switch Over.
- After the switchover is complete, verify the following:
- The cluster status is "Good".
- Services continue without interruption.
Test 2: Automatic failover
This test verifies that the failover mechanism is working properly.
- Simulate active node failure by performing one of the following:
- Unplug the network cable from the active node.
- Force the active node to shut down by pressing the physical power button for 10 seconds.
- Log in to the passive node.
- Go to High Availability Manager > Cluster.
- Verify the following:
- The passive node has become the new active node.
- The original active node is offline.
Test 3: Automatic rejoin after reconnecting offline node
This test verifies that after an offline node is reconnected to the cluster, it will automatically rejoin the cluster, and the cluster will resume HA functionality.
- After performing test 2, do one of the following:
- Reconnect the network cable to the offline node.
- Power on the offline node.
- On the other node, go to High Availability Manager > Cluster.
- Verify the following:
- The previously offline node automatically rejoins the cluster as the passive node.
- After synchronization is complete, the cluster status is "Good".

情境
我已經設置了一個 QNAP 高可用性 (HA) 叢集，並希望確認其運作正常。有哪些建議的方法可以測試其功能？
程式
要確認您的 HA 叢集 運作正常，請執行以下測試。
提示
- 在進行任何 HA 相關測試之前，務必進行完整的資料備份以防止資料丟失。
- 如果您的 HA 叢集 在生產環境中運行，請避免直接模擬電源或網絡故障。如有可能，請在非生產環境中進行這些測試。
- 在測試期間，密切監控 High Availability Manager 中的事件日誌和狀態變化。
測試 1：手動切換
此測試驗證切換機制是否正常運作。
- 前往High Availability Manager > 叢集.
- 確認當前主動和被動節點的狀態。
- 按一下管理, 然後選擇切換.
- 切換完成後，驗證以下內容：
測試 2：自動 容錯移轉
此測試驗證 容錯移轉 機制是否正常運作。
- 透過執行以下操作之一來模擬主動節點故障：
- 拔掉主動節點的網路線。
- 按住實體電源按鈕 10 秒以強制關閉主動節點。
- 登入被動節點。
- 前往High Availability Manager > 叢集.
- 驗證以下內容：
測試 3：重新連線離線節點後的自動重新加入
此測試驗證當離線節點重新連接到 叢集 後，它將自動重新加入 叢集，並且 叢集 將恢復 HA 功能。
- 在執行測試 2 後，執行以下操作之一：
- 在另一個節點上，前往High Availability Manager > 叢集.
- 驗證以下內容：
- 先前離線的節點自動重新加入 叢集 作為被動節點。
- 同步完成後，叢集 狀態為「良好」。
