Symptoms

在 vCenter 6.5 或更新版本上執行快照並停用靜止功能時，VMware 映射備份失敗，並顯示以下嚴重錯誤訊息。  
avvcbimage Info <43655>: Creating snapshot 'Avamar-<epoch><cid>', quiesceFS=FALSE
avvcbimage Info <42643>: Using vSphere CreateSnapshotTaskEX: snapshot name (Avamar-<epoch><cid>)
avvcbimage Info <14631>: Snapshot 'Avamar-<epoch><cid>' creation for VM '[Avamar] winvm/winvm.vmx' task still in progress, sleep for 3 sec
avvcbimage Warning <16277>: vSphere Task failed (application quiesce): An error occurred while quiescing the virtual machine. See the virtual machine's event log for details.
avvcbimage Warning <43652>: Snapshot 'Avamar-<epoch><cid>' creation for VM '[Avamar] winvm/winvm.vmx' task creation encountered a quiesce problem

avvcbimage FATAL <0000>: [IMG0003] The VMX '[Avamar] winvm/winvm.vmx' could not be snapshot

Cause

Avamar Proxy 並未使用名為「SnapShot Manager」的服務。當未使用此服務時，記錄會顯示下列內容：    
avvcbimage Info <40643>: NOT using SnapShot Manager - using proxy method of calling vSphere API functions
SnapShot Manager 是在 Avamar 公用程式節點上執行的服務，可透過 TCP 8543 （HTTPs://avamar.example.com:8543/snapshotmanager/） 存取。當所有 Proxy 使用此服務時，所有快照作業 （建立、刪除、整合） 工作都會集中到 Avamar 伺服器。若未使用此服務，Proxy 會透過標準 vSphere API 採取自己的快照作業。

vSphere API quiesce_fs=false snapshot 機制中導入的 Avamar 軟體缺陷：    
  • 含修正程式的 Avamar 18.2 proxy 309856 （或更新版本）
  • Avamar 19.1 Proxy  
Avamar Snapshot Manager 可能因為兩個可能原因而無法使用：   
  • 在這種情況下，網路或防火牆會在記錄中看到下列內容：   
avvcbimage Info <44028>: GET: curl_easy_perform -failed. Path: /snapshotmanager/about/, Curl Error: 7
或 
avvcbimage Info <44028>: GET: curl_easy_perform -failed. Path: /snapshotmanager/about/, Curl Error: 28
  • 使用者已停用或移除 Proxy 上 avvcbimageAll.cmd檔案中的 Snapshot Manager 選項，在此情況下，會看到下列專案：   
admin@182proxy:~> grep snapshotManager /usr/local/avamarclient/var/avvcbimageAll.cmd
##--snapshotManager=10.2X0.1X6.1X1

或

admin@182proxy:~> grep snapshotManager /usr/local/avamarclient/var/avvcbimageAll.cmd
admin@182proxy:~>

Resolution

因應措施：    
確認正在使用 Avamar Snapshot Manager：   
  • 確認 Avamar Proxy 可在 TCP 8543 上連接 Avamar 服務
或 
  • 重新註冊 Proxy 或將此行新增至 
    /usr/local/avamarclient/var/avvcbimageAll.cmd
     未提出任何意見 #：   
--snapshotManager==<avamar-ip-address or hostname>
解析度：
此問題已在 Avamar 19.1+ Proxy 累積修正程式中解決。  請為您的版本安裝最新的新更新以解決。
