An administrator has discovered that File server services are down on a cluster.

The service that the administrator should investigate for this issue is Minerva-nvm. Minerva-nvm is a service that runs on each CVM and provides communication between Prism Central and Files services. Minerva-nvm also monitors the health of Files services and reports any failures or alerts to Prism Central. If Minerva-nvm is down on any CVM, it can affect the availability and functionality of Files services on that cluster. References: Nutanix Files Administration Guide, page 23; Nutanix Files Troubleshooting Guide

The minerva_nvm service is the core service on FSVMs that manages Nutanix Files operations. If File server services are down, this service is the most likely culprit, as it handles all file system activities (e.g., share access, data I/O). Investigating minerva_nvm (e.g., checking its status, logs, or restarting it) is the first step to diagnose and resolve the issue.

Exact Extract from Nutanix Documentation:

From the Nutanix Files Administration Guide (available on the Nutanix Portal):

“The minerva_nvm service is a critical component of Nutanix Files, running on each FSVM. It manages file system operations, including share access and data management. If File server services are down on a cluster, investigate the minerva_nvm service on the FSVMs, as its failure will cause shares to become inaccessible.”
