你好，

关于这个问题https://next.nutanix.com/how-it-works-22/disk-fault-tollerance-8822，当1个驱动器失败时，在2个不同的主机上失败时，群体中将发生什么VM？将是任何数据丢失还是没有？VM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，

要清楚地了解您的要求，它是一个RF-2集群中的所有节点都会发生的情况，但不同节点上的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"}}}">

你好，艾洛纳。是的。我想知道数据和VM会有什么吗？

在这种情况下存在数据丢失。这两个磁盘都有风险，这两个副本都携带了相同块的数据，使得这种数据不可恢复。

就如何影响VM而言，这取决于什么样的数据。VM依赖于数据或拥有它可能挂起，崩溃，无法启动。
