你好，

关于这个问题https://next.nutanix.com/how-it-works-22/disk-fault-tollerance-8822，当2个不同主机上1个驱动器失败时，在带有RF2的群集中，VM会发生什么？会有任何数据丢失吗？VMS会重新启动吗？

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"}">

嗨，安东，

清楚地了解您要问的是，在所有节点运行的RF-2群集中会发生什么，但在不同的节点上有2个磁盘失败。那是对的吗？

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"}}}">

您好，Alona。是的。我想知道数据和VM会有什么？

在这种情况下，数据丢失有潜力。这两个磁盘都有风险，两个磁盘都包含相同数据的两个副本，从而使该数据不可恢复。

就这对VM的影响如何，这取决于哪种数据。依靠该数据或拥有的VM可能会悬挂，崩溃，无法启动。
