Nutanix NCP-US-6.5 Dumps

The most likely cause for this issue is that the file server resides on a single node cluster. A distributed share is a type of SMB share or NFS export that distributes the hosting of top-level directories across multiple FSVMs, which improves load balancing and performance. A distributed share cannot be created on a single node cluster, because there is only one FSVM available. A distributed share requires at least two nodes in the cluster to distribute the directories. Therefore, the option to use distributed share/export type instead of standard is not present when creating a share on a single node cluster. References: Nutanix Files Administration Guide, page 33; Nutanix Files Solution Guide, page 8

A single-node cluster cannot support a Distributed Share because it can only host one FSVM, whereas Distributed Shares require at least three FSVMs for distribution and high availability. This limitation causes the “Use Distributed Share/Export type instead of Standard” option to be absent when creating a share, as the cluster does not meet the minimum requirements.

Exact Extract from Nutanix Documentation:

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

“Distributed Shares require a minimum of three FSVMs to ensure scalability and high availability, which typically requires a cluster with at least three nodes. On a single-node cluster, only Standard Shares are supported, and the option to create a Distributed Share will not be available in the Files Console.”

Nutanix Files, part of Nutanix Unified Storage (NUS), generates logs for file service operations, which can be forwarded to a syslog server for centralized logging and monitoring. The process to configure syslog forwarding for Nutanix Files involves interacting with the File Server Virtual Machines (FSVMs), as they handle the file services and generate the relevant logs.

Analysis of Options:

Option A (Configure the syslog in Prism Element): Incorrect. Prism Element manages cluster-level settings, such as storage and VM configurations, but it does not provide a direct interface to configure syslog forwarding for Nutanix Files. Syslog configuration for Files is specific to the FSVMs.

Option B (Configure the syslog in Files Console): Incorrect. The Files Console (accessible via Prism Central) is used for managing Files shares, FSVMs, and policies, but it does not have a built-in option to configure syslog forwarding. Syslog configuration requires direct interaction with the FSVMs.

Option C (Use the CLI in an FSVM): Correct. Nutanix Files logs are managed at the FSVM level, and syslog forwarding can be configured by logging into an FSVM and using the command-line interface (CLI) to set up the syslog server details. This is the standard method documented by Nutanix for enabling syslog forwarding for Files.

Option D (Use the CLI in a CVM): Incorrect. The Controller VM (CVM) manages the Nutanix cluster’s storage and services, but it does not handle Files-specific logging. Syslog configuration for Files must be done on the FSVMs, not the CVMs.

Configuration Process:

To configure syslog forwarding, the administrator would:

SSH into one of the FSVMs in the Files deployment.

Use the nutanix user account to access the FSVM CLI.

Run commands to configure the syslog server (e.g., modify the /etc/syslog.conf file or use Nutanix-specific commands to set the syslog server IP and port).

Restart the syslog service on the FSVM to apply the changes.This process ensures that Files logs are forwarded to the specified syslog server.

Exact Extract from Nutanix Documentation:

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

“To forward Nutanix Files logs to a syslog server, you must configure syslog settings on each FSVM. Log in to an FSVM using SSH and the ‘nutanix’ user account. Use the CLI to update the syslog configuration by specifying the syslog server’s IP address and port. After configuration, restart the syslog service to apply the changes.”

Nutanix Files, part of Nutanix Unified Storage (NUS), requires pre-upgrade checks to ensure a successful upgrade (e.g., from version 3.7 to 4.1). The error “Sub task poll timed out” indicates that a subtask during the pre-upgrade check did not complete within the expected time, likely due to communication or resource issues among the File Server Virtual Machines (FSVMs).

Analysis of Options:

Option A (Increase upgrades timeout from ecli): Incorrect. The ecli (Entity CLI) is not a standard Nutanix command-line tool for managing upgrades, and “upgrades timeout” is not a configurable parameter in this context. While timeouts can sometimes be adjusted, this is not the initial troubleshooting step, and the error suggests a deeper issue (e.g., communication failure) rather than a timeout setting.

Option B (Check there is enough disk space on FSVMs): Incorrect. While insufficient disk space on FSVMs can cause upgrade issues (e.g., during the upgrade process itself), the “Sub task poll timed out” error during pre-upgrade checks is more likely related to communication or task execution issues between FSVMs, not disk space. Disk space checks are typically part of the pre-upgrade validation, and a separate error would be logged if space was the issue.

Option C (Examine the failed tasks on the FSVMs): Incorrect. Examining failed tasks on the FSVMs (e.g., by checking logs) is a valid troubleshooting step, but it is not the initial step. The “Sub task poll timed out” error suggests a communication issue, so verifying connectivity should come first. Once connectivity is confirmed, examining logs for specific task failures would be a logical next step.

Option D (Verify connectivity between the FSVMs): Correct. The “Sub task poll timed out” error indicates that the pre-upgrade check could not complete a subtask, likely because FSVMs were unable to communicate with each other or with the cluster. Nutanix Files upgrades require FSVMs to coordinate tasks, and this coordination depends on network connectivity (e.g., over the Storage and Client networks). Verifying connectivity between FSVMs (e.g., checking network status, VLAN configuration, or firewall rules in a highly secured environment) is the initial troubleshooting step to identify and resolve the root cause of the timeout.

Why Option D?

In a highly secured environment, network restrictions (e.g., firewalls, VLAN misconfigurations) are common causes of communication issues between FSVMs. The “Sub task poll timed out” error suggests that the pre-upgrade check failed because a task could not complete, likely due to FSVMs being unable to communicate. Verifying connectivity between FSVMs is the first step to diagnose and resolve this issue, ensuring that subsequent pre-upgrade checks can proceed.

Exact Extract from Nutanix Documentation:

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

“If the pre-upgrade check fails with a ‘Sub task poll timed out’ error, this typically indicates a communication issue between FSVMs. As an initial troubleshooting step, verify connectivity between the FSVMs, ensuring that the Storage and Client networks are properly configured and that there are no network restrictions (e.g., firewalls) preventing communication.”
