取代叢集中的節點 - AWS Snowball 邊緣 開發人員指南

本文為英文版的機器翻譯版本，如內容有任何歧義或不一致之處，概以英文版為準。

取代叢集中的節點

若要取代節點，您必須先訂購替換。您可以從 主控台、 AWS CLI或其中一個 AWS SDKs 訂購替換節點。如果您是從主控台訂購替換節點，則可以針對任何尚未取消或完成的任務訂購替換節點。然後，您將運作狀態不佳的節點與叢集取消關聯、將替換節點連接至您的網路，並解鎖叢集，包括替換節點、將替換節點與叢集建立關聯，以及在 Snowball Edge 服務上重新啟動 Amazon S3 相容儲存。

從主控台訂購替換節點

  1. 登入 AWS Snow 系列管理主控台。

  2. 針對屬於您已從任務儀表板建立之叢集的節點，尋找並選擇一個任務。

  3. 針對 Actions (動作)，選擇 Replace node (取代節點)。

    這樣做會開啟任務建立精靈的最後一個步驟，而所有設定與原先建立叢集的方式相同。

  4. 選擇建立作業。

您的替代 Snowball Edge 現在已準備就緒。使用下列程序從叢集中移除運作狀態不佳的節點。

從叢集移除節點

  1. 關閉要移除的節點。如需詳細資訊，請參閱關閉 Snowball Edge。

  2. 使用 describe-cluster命令來確保無法連線運作狀態不佳的節點。這由 NetworkReachability 物件UNREACHABLEState名稱的 值表示。

  4. 使用 disassociate-device命令從叢集取消關聯和移除運作狀態不佳的節點。

    
snowballEdge disassociate-device --device-id device-id --manifest-file path/to/manifest/file.bin --unlock-code unlock-code --endpoint https://ip-address-of-unhealthy-device
    範例 disassociate-device 命令的輸出
    
Disassociating your Snowball Edge device from the cluster. Your Snowball Edge device will be disassociated from the cluster when it is in the "DISASSOCIATED" state. You can use the describe-cluster command to determine the state of your cluster.

  5. 再次使用 describe-cluster命令，以確保運作狀態不佳的節點與叢集取消關聯。

            }
        }
    ]
}

  6. 關閉並傳回運作狀態不佳的裝置 AWS。如需詳細資訊，請參閱關閉 Snowball Edge 和傳回 Snowball Edge 裝置。

當替代裝置送達時，請使用下列程序將其新增至叢集。

新增替代裝置

  1. 放置叢集的替換裝置，以便您可以存取所有裝置的正面、背面和頂部。

  2. 開啟節點電源，並確保節點連接到與叢集其他部分相同的內部網路。如需詳細資訊，請參閱連線至本機網路。

  3. 使用 unlock-cluster命令並包含新節點的 IP 地址。

    
snowballEdge unlock-cluster --manifest-file path/to/manifest/file.bin --unlock-code unlock-code --endpoint https://ip-address-of-cluster-device --device-ip-addresses node-1-ip-address node-2-ip-address new-node-ip-address

    新節點的狀態會是 ，DEGRADED直到您在下一個步驟中將其與叢集建立關聯為止。

  4. 使用 associate-device命令將取代節點與叢集建立關聯。

    
snowballEdge associate-device --device-ip-address new-node-ip-address
    範例 associate-device 命令輸出的
    
Associating your Snowball Edge device with the cluster. Your Snowball Edge device will be associated with the cluster when it is in the ASSOCIATED state. You can use the describe-device command to determine the state of your devices.

  5. 使用 describe-cluster命令來確保新節點與叢集相關聯。
