Node failure questoin

Hey, @KC93  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.

So the rebuild is a fully distributed operation across all nodes and drives, it’s both very fast and the workload per node is minimised to avoid bottlenecks and to reduce the impact to running workload.

Although, the speed of rebuild operation will depend on lots of factors:
 

1) Size of the cluster. 

2) number/type of drives (e.g.: NVMe, SATA-SSD, DAS-SATA) 

3)Network speed and connectivity. etc

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

These will definitely help and give you a good insight.
