Symptoms
觀察到備份故障指示燈。
當備份程序因 Data Domain Replicator (DDR) 權杖問題而失敗時,會記錄下列症狀。
- Avamar 記錄會報告無效權杖的使用方式和多個錯誤代碼。
- 備份失敗並遺失
ddr_files.xml檔案中所定義。 - 致命的伺服器連接問題會阻止初始化。
- 命令執行以退出代碼 10008 結束,表示無法與伺服器建立連接。

Cause
備份操作失敗,因為 ddrmaint-service Avamar Server 未執行。當此服務中斷時,Avamar 用戶端無法取得有效的 DDR 驗證權杖,導致一連串的錯誤導致備份失敗。
關鍵影響因素
- 可使用
dpnctl輸出指示ddrmaint-service已關閉。 - Data Domain 伺服器的驗證失敗,產生「無效權杖」錯誤。
- 所需的檔案
/ddr_files.xml未生成,導致備份不完整。 - 後續的 DDR 錯誤會使備份無法發佈或認可。

重新啟動 DDR 維護服務。
循序漸進程序
- 使用具有管理權限的帳戶登入 Avamar 伺服器。
- 檢查目前狀態
ddrmaint-service確認其已關閉。# Verify service status $ dpnctl status | grep ddrmaint-service ddrmaint-service status: down - 啟動服務。
# Start the DDR maintenance service $ dpnctl start ddrmaint-service - 驗證服務是否正在運行。
# Re‑check status to ensure it is up $ dpnctl status | grep ddrmaint-service ddrmaint-service status: up - 確認備份正在完成,沒有”
invalid token“錯誤。- 執行測試備份或等待下一個排定備份完成。
- 檢查 Avamar 記錄中是否沒有錯誤,例如:
41439小10542小10509小17964,或8941。# Example of a successful backup log snippet 2024-01-30 02:15:12 avtar Info <10642>: Backup completed successfully. 2024-01-30 02:15:12 avtar Info <12530>: Backup was committed to the DDR. - 確認檔案
/ddr_files.xml備份完成後就會顯示。
警示:重新啟動
ddrmaint-service 暫時中斷任何作用中的 DDR 通訊。在執行重新啟動之前,請確定沒有執行任何關鍵備份工作。
注意:如果服務無法啟動,請檢閱
/usr/local/avamar/var/log/dpnctl.log 檔以獲取錯誤詳細資訊,並在重試之前解決任何基本問題(如磁碟空間、許可權問題)。
