A three-node cluster has a Nutanix Files instance with three FSVMs. What happens after a node failure?

Nutanix Files is a highly available service. The File Server VMs (FSVMs) that constitute a Nutanix Files cluster are protected by Nutanix High Availability (HA). In the event of a physical node failure, the AHV cluster's HA mechanism will automatically restart the FSVM that was running on the failed node on one of the surviving nodes in the cluster. This ensures that the file services remain operational with minimal disruption. The primary goal of the system is to maintain service availability.

A: Live migration is a proactive, non-disruptive process that requires the source host to be operational. It cannot be performed from a host that has failed unexpectedly. B: FSVMs are critical service VMs, not simple agent VMs. They are specifically designed to be restarted by HA to maintain the availability of the Nutanix Files service. C: While VM-to-VM anti-affinity rules are used to keep FSVMs on separate nodes during normal operation, HA restart logic takes precedence during a failure to ensure service recovery.

2. Nutanix Solutions Documentation. (2023). Nutanix Files 4.3 Design Guide. Section: "High Availability." The guide states: "If a CVM or Nutanix node fails, the FSVMs restart on other nodes in the cluster... AHV detects the node failure and restarts the FSVM on another node."
