在辅助节点上,我们可能会在日志中看到这些错误(通常位于 C:\Program Files\avs\var 目录中):

Cause

Hyper-V 弹性更改跟踪 (RCT) 扩展区位于发送到 Data Domain 的令牌请求中。如果 RCT 扩展区过多,则 DDR 令牌请求会失败。
avagent 软件修复禁止在令牌请求中包含 RCT 扩展区,因为它们不是必需的。

Resolution

要解决此问题,请执行以下操作:
  • 将 Avamar Server 升级到版本 19.4.100-124 或更高版本
  • 该修复包含在 Avamar 版本 19.4 及更高版本的软件版本中

Additional Information

即使在所有群集节点上应用了 avagent 软件修复,Hyper-V 备份仍可能失败。如果是这种情况,则其他问题可能会导致该问题。这些问题(例如 Avamar Utility Node 上停止响应的 Java 进程或 DDRmaintlog 轮换失败)需要 Avamar 支持部门进行调查。
