Symptoms

在执行已禁用停顿功能的快照时，vCenter 6.5 或更高版本上的 VMware 映像备份失败，并显示以下致命错误消息。  
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

Cause

Avamar 代理未使用名为“SnapShot Manager”的服务。如果未使用此服务，日志将显示以下内容：    
avvcbimage Info <40643>: NOT using SnapShot Manager - using proxy method of calling vSphere API functions
SnapShot Manager 是在 Avamar 应用工具节点上运行的服务，可通过 TCP 8543 （https://avamar.example.com:8543/snapshotmanager/） 访问。当所有代理使用此服务时，所有快照操作（创建、删除、整合）任务将集中到 Avamar Server。如果未使用此服务，代理将通过标准 vSphere API 执行自己的快照操作。

vSphere API quiesce_fs=false 快照机制中引入了 Avamar 软件缺陷：    
  • 带热修复程序的 Avamar 18.2 代理309856（或更高版本）
  • Avamar 19.1 代理  
由于以下两个潜在原因，Avamar Snapshot Manager 可能不可用：   
  • 在其中的网络或防火墙中，日志中会显示以下内容：   
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
  • 用户已在代理上的 avvcbimageAll.cmd 文件中禁用或删除 Snapshot Manager 选项，在这种情况下，会看到以下内容：   
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

解决办法：    
确认正在使用 Avamar Snapshot Manager：   
  • 验证 Avamar 代理是否可以在 TCP 8543 上连接 Avamar 服务
或者 
  • 重新注册代理或将此行添加回 
    /usr/local/avamarclient/var/avvcbimageAll.cmd
     不带任何注释 #：   
--snapshotManager==<avamar-ip-address or hostname>
分辨率：
此问题已在 Avamar 19.1+ 代理累积热修复程序中得到解决。  请为您的版本安装最新的新更新以解决。
