我迷失在这怎么做：
嗨…
系统：Windows 2008 R2 Hyper-V服务器场与故障转移群集一起运行，并将EVA 4400作为后端。
当我将一个新磁盘附加到一个虚拟机时，它会失败，当我尝试启动它。
如果我把虚拟机移动到另一个节点，比如说节点1，我可以添加这个磁盘，我可以让它们启动。
如果我将VM移回问题出现并且VM正在运行的节点2，则在实时迁移期间出现错误，并且VM将故障转移回运行的node1。
所以就像在节点2上的Hyper-V有问题，而不是在节点1上。同样，节点3也有同样的问题。
重新启动节点不是一个选项，因为我稍后会再次遇到这个问题，因为不是所有的虚拟机都可以在节点1上运行，这意味着我的客户端公司将会遇到节点1上没有运行的虚拟机的停机时间。
任何解决这个？ 也许我错过了更新？ 已经两年了

在hyper-v VMMS日志中，我有这样的：
“ServerName”未能执行该操作。 虚拟机未处于有效状态以执行操作。 （虚拟机ID 0A6CC4A9-39D6-4413-8CF0-B6DAA35B68D7）
你的存储是否通过了集群validationtesting？ 我唯一一次遇到实时迁移的问题是当我安装了一个dvd / iso或不在CSV或共享存储上的东西时。 关键是CSV或SHARED存储。
当你看到x：\ xxx.vhd时，会看到c：\ clusterstorage / volume1
我已经看到了几百次hyper-v r2 CSV安装的唯一失败是人为错误！
