我有一个VM,最初运行在具有Hyper-Vangular色的Windows Server 2008 R2上。 访客是Server 2012,它只是作为域控制器(在另一台物理机上运行的SBS 2011服务器的备份)。
我通过closures虚拟机来移动虚拟机,将文件复制到新的Hyper-V Server 2016主机,并使用Hyper Vpipe理来导入虚拟机。 Altaro备份成功,但警告“备份快照不是应用程序一致的,备份将以崩溃一致模式进行。
在VM的事件日志中,我有这些消息:
ESENT: lsass (592) An attempt to open the file "\\?\Volume{b0cbe895-ed69-11e6-80b0-806e6f6e6963}\Windows\NTDS\ntds.dit" for read only access failed with system error 32 (0x00000020): "The process cannot access the file because it is being used by another process. ". The open file operation will fail with error -1032 (0xfffffbf8).
VSS: A VSS writer has rejected an event with error 0x800423f4, The writer experienced a non-transient error. If the backup process is retried, the error is likely to reoccur. . Changes that the writer made to the writer components while handling the event will not be available to the requester. Check the event log for related events from the application hosting the VSS writer.
vmicvss: The VSS writer NTDS failed with status 11 and writer specific failure code 0x800423F4.
我认为这是从2008 R2主机迁移到2016年的一个问题,因此我降级了域控制器,删除了AD和DNSangular色,然后干净地安装了Server 2012 R2,重新添加了这些angular色并提升了服务器回到DC,但问题依然存在。
有任何想法吗? 这似乎是在虚拟机上的东西造成快照失败,但我不知道如何解决与目录服务相关的文件访问问题。
显然,这是Hyper-V 2016和2012 R2域控制器作为虚拟机的已知问题。 微软应该正在为此做一个修复。
