Symptoms
Hyper-V 群集備份失敗,並出現以下錯誤:
從共用群集 var 目錄記錄:
-
avhypervvss Error <0000>: The plugin on remote client HYPERVNODE4 (192.168.1.1) terminated with code 10007: miscellaneous error avhypervvss Error <0000>: The remote client HYPERNODE4 failed to start its backup sub-workorder in predefined time. Please examine the log 'Hyper-V_5pm-Hyper-_V-123456789-3032-Hyper-V_VSS.log' on client HYPERVNODE4 for more information. avhypervvss Error <13810>: Unable to forward a ctl message to the remote client '192.168.1.1', result code: 3. avhypervvss Error <41106>: [AV-CLUSTER0] is unable to wakeup sub-workorder on [HYPERVNODE4]. avhypervvss Error <42468>: Failed to update snapshot details from remote clients avhypervvss Error <41659>: Backup did not complete successfully
從受影響節點上的備份記錄 (C:\Program Files\avs\var):
-
avhypervvss Error <17114>: Timed out while waiting for a VSS snapshot synchronization event from the primary plugin. avhypervvss Error <41632>: Failed to setup and notify primary. avhypervvss Error <41659>: Backup did not complete successfully
Cause
此故障是由 Hyper-V 群集中的主要節點和輔助節點之間的 CTL 消息交換中的通信延遲引起的。這些延遲會妨礙 VSS 快照的及時同步,從而導致備份失敗。
Resolution
若要解決此問題,請提高 avhypervvss.cmd 位於共用叢集中的檔案 var 目錄 (如在, C:\ClusterStorage\Volume1\Avamar\var):
新增下列標誌:
--request-ctl-timeout=600000
--subworkorder-timeout=20
--request-ctl-timeout=600000:增加節點之間的內部 CTL 逾時 (預設為 60 秒)。--subworkorder-timeout=20:設置後端用戶端啟動子工單的等待時間(以分鐘為單位)(預設為 5 分鐘)。
⚠️ 確定所有相關節點上的檔案已更新,然後重新啟動備份程序。
