The following warning occurred to customer Nutanix.

WARN: Cluster cannot tolerate 1 node failure.

As a result of the search, we found the following:
impact Cluster can not tolerate single node (RF2) or two node (RF3) failure and guarantee available storage to provide data redundancy.

The usage warning is 26.93 TiB of the 26.41 TiB recommended usage.

The question here is, if one out of four nodes fails,
Is it still possible to operate with RF1?
Or will the cluster hang up?

On the prism element main dashboard click on “Data Resiliency Status” and you can see what is causing this.

Thank you for answer. The current cause is confirmed to be caused by high storage usage. What I am curious about is what happens if 1 out of 4 nodes fails in this state. I wonder if the cluster stops or if duplicate replication is not possible, but it is possible to use the cluster.
