Symptoms

Avamar Hyper-V 備份失敗或完成,但有例外狀況。特定 Hyper-V 節點的所有 VM 都已從備份中排除,並顯示錯誤:「Error :虛擬機器「」的檢查點建立已失敗,並會從備份中略過。

備份記錄中的相關部分:
avhypervvss Error : Checkpoint creation for Virtual machine '' has failed and will be skipped from backup. For details, please check 'winclustersvc.log'.

avhypervvss Info : --------------------Start [EMC Avamar Plug-in Service for Windows] log ----------

winclustersvc.log對應部分位於「EMC Avamar backup cluster client for 」的擁有者C:\Program Files\avs\var\資料夾中。您可以從容錯移轉叢集管理員判斷。

若要顯示這些訊息,必須在 winclustersvc的用戶端上啟用偵錯。本文的「其他資訊」區段說明如何啟用偵錯。
winclustersvc WARN:  WMI API returned error: 'Failed to create checkpoint on collection 'AvamarBackup_-app-' ().
The operation failed.
Guest cluster validation on VM group 'AvamarBackup_-app-' () failed for checkpoint creation.
Size of the VM group 'AvamarBackup_-app-' () is not same with the size of the guest cluster.'  
winclustersvc DEBUG: : Retry '1', WMI API 'CreateSnapshot' for VMGroup 'AvamarBackup_-app-' 
winclustersvc DEBUG: ===> ValidateOutput  
winclustersvc DEBUG: WMI API return value is: '4096' 
winclustersvc DEBUG: Waiting for Job to complete... 
winclustersvc DEBUG: WMI job completed with status '10'  
winclustersvc WARN:  WMI API returned error: 'Failed to create checkpoint on collection 'AvamarBackup_-app-' ().
The operation failed.
Guest cluster validation on VM group 'AvamarBackup_-app-' () failed for checkpoint creation.

Cause

當在備份資料集的特定 Hyper-V 節點選取數個 VM 時,Microsoft WMI API 會產生這些訊息。

Resolution

Hyper-V 節點應安裝所有最近的 Microsoft 更新。

沒有一個虛擬機器已設定磁片、共用磁片或客體中 CSV。它不支援 Hyper-V 映射備份。

解決 方案:
  • 使用較小的群組。 
  • 從備份資料集中的特定節點選取較少的 VM。
  • 向 Microsoft 開立案例,以解決 Hyper-V 節點上的 WMI API 問題。  

Additional Information

若要在winclustersvc中啟用偵錯:
  1. 使用 Notepad 在 Hyper-V 節點上的 C:\Program Files\avs\var\資料夾中建立winclustersvc.cmd - 「EMC Avamar backup cluster client for 」 的擁有者
  2. 新增 --debug 至它。
  3. 在 Hyper-V 節點上重新開機「EMC Avamar Plug-in Service for Windows」。 
  4. 重新執行備份以重現問題。
