据我所知，如果驱动失败，Nutanix将立即重建数据。我可以知道节点故障是否，如果在现有群集中具有足够的节点和容量，Nutanix会触发多长时间？谢谢

Hey,\u00a0@KC93<\/user-mention>\u00a0 so the rebuilding process starts as soon as the node goes down but time to rebuild depends upon the amount of data that was present on the failed node and other factors too. Prism will continue to show the resiliency status as critical unless entire data is rebuilt.<\/p>

So the rebuild is a fully distributed operation across all nodes and drives, it\u2019s both very fast and the\u00a0workload per node is minimised to avoid bottlenecks and to reduce the impact to running workload.<\/p>

Although,\u00a0the speed of rebuild operation will depend on lots of factors:
\u00a0<\/p>

1) Size of the cluster.\u00a0<\/p>

2) number\/type of drives (e.g.: NVMe, SATA-SSD, DAS-SATA)\u00a0<\/p>

3)Network speed and connectivity. etc<\/p>

Here is a very useful blog post which explains the above in detail:\u00a0http:\/\/www.joshodgers.com\/2018\/05\/30\/nutanix-resiliency-part-1-node-failure-rebuild-performance\/<\/a>\u00a0for RF2 clusters.<\/p>

As i know that if drive failure, Nutanix will rebuilt the data immediately. May i know if node failure, how long does the Nutanix will trigger to rebuilt if have sufficient node and capacity in existing cluster?

嘿， @kc93因此，重建过程在节点下降后立即开始，但是重建的时间取决于失败的节点和其他因素上存在的数据量。除非重建整个数据，否则PRISM将继续表现出至关重要的弹性状态。

因此，重建是所有节点和驱动器的完全分布的操作，它既快速，又可以最大程度地减少每个节点的工作量，以避免瓶颈并减少对跑步工作负载的影响。

虽然，重建操作的速度将取决于许多因素：

1）群集的大小。

2）驱动器的数量/类型（例如：NVME，SATA-SSD，DAS-SATA）

3）网络速度和连接性。ETC

这是一篇非常有用的博客文章，详细说明了上述内容：http://www.joshodgers.com/2018/05/05/30/nutanix-isility-part-part-1-node-failure-rebuild-performance/对于RF2簇。

这些肯定会有所帮助，并为您提供良好的见识。：微笑：

你好Anishwalia20，，，，

您非常有帮助，并感谢您的信息。

因此，节点重建过程将立即开始，并且与驱动器故障相同，对吗？当我显示一些文档时，说应该等待60秒，然后开始重建过程。我有点困惑。谢谢

嘿 @kc93，再次感谢您的客气话。

很高兴我能有所帮助。

它将立即开始。不，对于60秒的事情，这不是事实，那只是一些背景策展人服务任务，但它将立即开始。

您也可以分享文档吗？

Hey @KC93<\/user-mention>, thanks again for your kind words.<\/p>

Glad that I could be of some help.<\/p>

\u00a0<\/p>

It will start immediately. No that\u2019s not true about the 60 seconds things, that\u2019s just some of the background curator service task running, but it will start immediately.<\/p>

\u00a0<\/p>

Can you share the document too?<\/p>
