适用场景

  • SnapCenter 3.0、3.0.1、4.0、4.1、4.1P1
  • 适用于VMware的SnapCenter 插件
  • vSphere 6.x
  • ESXi 6.x

问题描述

在备份后查看虚拟机时、仍存在一个或多个在备份前不存在的虚拟机快照、备份完成后会显示警告。

如果已达到31个快照的限制、则备份将完全失败。

在插件的AEGIS日志中、您可能会看到以下内容:

com.netapp.aegis.vsphere.VsphereService An error occurred while quiescing the virtual machine. See the virtual machine's event log f or details. com.netapp.aegis.backup.QuiesceManager VMware snapshot status :

Failure com.netapp.aegis.backup.QuiesceManager exceptionDuringQuiesce : true ErrorCode (-1), ErrorMessage (Exception occurred when quiescing virtual machines: cluster_node1, cluster_node2, standalone-vm.

Please check 'Create virtual machine snapshot' task on vSphere Web Client or SnapCenter Plug-in for VMware vSphere logs f or detailed error message.)

在备份期间、您可以看到已创建一些虚拟机快照(VMware快照)、然后在作业结束时、SC未尝试删除这些快照、因为备份期间存在连接问题描述。这意味着SC与vCenter的通信将中断、并且无法识别VMware快照创建是否已完成、无论是否存在错误。

有关信息、请参见aegis.log

在此处、您可以看到由于连接错误而在创建快照时出现异常

在VMware日志(vpxd.log)中、您可以看到"CreateSnapshot"已完成、但未显示任何错误
