Symptoms
Hyper-V 群集备份失败,并显示以下错误:
从共享群集 var 目录日志:
-
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
从受影响节点上的备份日志 (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
故障是由 Hyper-V 群集中的主节点和辅助节点之间的 CTL 消息交换中的通信延迟引起的。这些延迟会阻止 VSS 快照的及时同步,从而导致备份失败。
Resolution
要解决此问题,请增加 avhypervvss.cmd 位于共享群集中的文件 var 目录(如 C:\ClusterStorage\Volume1\Avamar\var):
添加以下标志:
--request-ctl-timeout=600000
--subworkorder-timeout=20
--request-ctl-timeout=600000:增加节点之间的内部 CTL 超时(默认值为 60 秒)。--subworkorder-timeout=20:设置后端客户端启动子工单的等待时间(以分钟为单位)(默认值为 5 分钟)。
⚠️ 确保在所有相关节点上更新文件,然后重新启动备份过程。
