你好,

关于这个问题https://next.nutanix.com/how-it-works-22/disk-fault-tollerance-8822RF2集群中的虚拟机，如果两个主机上的一个驱动器出现故障，会发生什么?是否会有数据丢失?vm重启吗?

谢谢!

There is a potential of data loss in this situation. There a risk that the both disks carry both copies of the same chunk of data making this data non-recoverable.<\/p>

In terms of how this affects VMs, it depends on what kind of data that was. VMs that rely on that data or own it may hang, crash, fail to boot.<\/p>","className":"post__content__best_answer"}">

你好安东,

为了清楚地理解您所问的问题，在所有节点都运行但不同节点上有2个磁盘故障的RF-2集群中会发生什么。那是正确的吗?

Hi Anton,<\/p>

To understand clearly what you are asking is what will happen in an RF-2 cluster with all nodes running but with 2 disks failures on different nodes. Is that correct?<\/p>","quoteUsername":"Alona","translations":{"Common":{"like":"Like","unlike":"Unlike"},"Forum":{"Quote":"Quote","Share":"Share"}}}">

你好,Alona。是的。我想知道数据和虚拟机将会是什么?

在这种情况下，有可能丢失数据。存在这样的风险，即两个磁盘携带同一数据块的两个副本，从而使该数据不可恢复。

就这对vm的影响而言，这取决于数据类型。依赖这些数据或拥有这些数据的虚拟机可能会挂起、崩溃、无法启动。
