hyper-v – Hyperv-V创建神秘的.avhdx文件并填满磁盘空间

我有 Windows Server 2016.我的服务器上也有Hyper-V角色.每天5:36我都有错误,磁盘已满,我的虚拟机正在停止.在Hyper-V日志中：

我试着在5点36分之前没有睡觉,看看是怎么回事,因为在我的磁盘上我有80G的可用空间. DBS82-Data.vhdx接近100G.所以,我试着不睡觉,我看到,在磁盘D上创建了DBS82-Data_E8D5659C-CBA3-4813-8543-F30F264A7A2F.avhdx文件,它填满了磁盘空间.此外,在Hyper-V管理器中,我看到所有虚拟机状态合并的状态.那是什么 ？我可以在哪里管理它？因为在Windows Server 2008中的hyper-v上,我没有看到这个问题(功能).

您已经启用了需要为 merged的 Hyper-V Checkpoints,或者有一个额外的快照管理软件(备份或复制),它将命令发送到Hyper-V以创建检查点/快照.

我将首先在上述时间调查系统/应用程序日志,以找出问题的根本原因.
