Nutanix File and NFS Mount Examples

The objective of this post is to provide inputs on requirement of using NFS exports. Nutanix Files implemented NFSv4 Support from Files 3.0.0.1 and since then Nutanix Files has come as a long way. Along with the release of Files 3.5, it now supports NFSv3 as well. They are enabled by default and depends on the NFS Client. [quote]In order to configure and utilize NFSv4 exports minimum required files version is 3.0.x In order to configure and utilize NFSv3 exports minimum required files version is 3.5.x [/quote] From 3.5 onward, V4 and V3 both are enabled by default. However, if you want to disable a specific version support based on requirement. It is achievable from UI. Self Service Restore is supported on NFS based exports from Files 3.5 onward for legacy and new exports. [b]Protocol Management → “Directory Services” → “Use NFS Protocol” → “Show NFS Advanced Options”[/b] [img]https://lh3.googleusercontent.com/7yg_BcwLhX13xo-Ov00VdEnawasj637u521nCti6lzWGxyZQJNyfMJHxKXxjs

Command line access to Nutanix File Server VM (FSVM) via SSH - Nutanix Files

An administrator may wish to log in to FSVM, for example, to perform network troubleshooting tasks.This can be achieved by establishing command line access to one of the CVMs on the cluster first and then logging in to FSVM. Please see step-by-step example below.Log in to CVM. Optionally, verify IP address configured on FSVM:$ ssh nutanix@10.123.124.125Nutanix Controller VMnutanix@10.123.124.125's password: Last login: Mon Oct 14 23:20:52 2019 from 10.245.246.237nutanix@NTNX-14SM71070032-A-CVM:10.123.124.125:~$ ncli fs ls Uuid : db890ac6-abcd-12ef-34ab-c6240654b029 Name : EXAMPLE-FS Version : 3.5.2 Container ID : 0005922b-abcd-12ef-34ab-002590c84bb8::81306 Container Uuid : 714c4d88-abcd-12ef-34ab-508b29c4a6d8 Virtual IP address : 10.124.245.125 [...]From CVM log in to FSVM:nutanix@NTNX-14SM71070032-A-CVM:10.123.124.125:~$ ssh nutanix@10.124.245.125FIPS mode initializedNutanix

Nutanix Files SMB Share Default Permission

Files currently supports SMB 2.0 and SMB 2.1, SMB 3.0 protocol. For SMB 3.0, it is important to note that Files has started supporting some of SMB 3.0 Features like SMB3 Signing ( 3.2.0 onward) and SMB3 Encryption support is coming with coming releases. We do not have any plans to support the SMB 1.0 protocol, given that this is no longer even supported by Microsoft for security reasons Nutanix Files assigns default permissions for newly created SMB shares. There are three default (BUILTIN) groups for Nutanix Files: Administrators, Users, Backup Operators. The [b]BUILTIN\Administrators[/b] group includes [b]\Domain Admins[/b], as well as any [b]file server admins[/b] you specify from Prism or the CLI. The [b]BUILTIN\Users[/b] group contains [b]\Domain[/b] Users. The [b]BUILTIN\Backup[/b] Operators group is empty by default but can include any backup admins you specify from Prism or the CLI. [b]The default permissions assigned to the Administrators and Users groups depend on

Antivirus for Nutanix Files : ICAP servers

In order to protect Nutanix files users from malware and viruses, you need to address both the client and the file server. Nutanix currently supports third party vendors that use Internet Content Adaptation Protocol ( ICAP ) servers.   ICAP, which is supported by a wide range of security vendors and products, is a standard protocol that allows file and web servers to be integrated with security products. Nutanix chose this method to give customers wide latitude in selecting the antivirus solution that works best for their specific environment.   Following is the workflow for an ICAP-supported antivirus solution:   An SMB client submits a request to open or close a file.   The file server determines if the file needs to be scanned, based on the metadata and virus scan policies. If a scan is needed, the file server sends the file to the ICAP server and issues a scan request.   The ICAP server scans the file and reports the scan results back to the file server.   Th

How to delete Nutanix Files snapshots for space reclamation?

In certain cases you might choose to reclaim space on the cluster by removing old snapshots. Nutanix files takes two types of snapshots.  External snapshots: The external snapshots are taken by the files protection domain (PD) which takes the snapshots of the whole Nutanix File server.   Internal snapshots: Internal snapshots are the snapshots taken at the share level which leverage ZFS directly. It can be the Self Service Restore snapshots or the third party backup snapshots using CFT API.  If need be, the external file server PD snapshots can be removed directly from the prism UI -> Protection Domain -> local snapshot page.The internal snapshots can be removed using the afs command line utility. If you choose to remove the internal snapshots the following KB article walks through the step by step process along with the afs commands needed. https://portal.nutanix.com/kb/000005851

Moving Win DFS Namespace to Nutanix Files

I’m standing-up a Nutanix File cluster and want to move an existing WIndows DFS Namespace to the cluster. The namespace needs to remain the same as it is used by web apps. I thought I could simply add the AFS cluster as a Namespace server, replicate the files, and then remove the old namespace servers. However, when I go to add the new namespace server, it wants a local folder location which isn’t available. I was sure I saw that Nutanix Files is compatible with Windows DFS but I don’t know what I’m missing. Suggestions?

Nutanix Files :- Exports and Shares Basics

There are two types of SMB shares and NFS exports.SMB shares:Distributed (previously called home). Standard (previously called general).NFS exports:Distributed (previously called sharded). Standard (previously called nonsharded).A standard share is an SMB share or NFS export hosted by a single FSVM. A distributed share spreads the workload by distributing the hosting of top-level directories across FSVMs, which also simplifies administration.Distributed shares and exports don’t allow files in the root. Unlike distributed shares and exports, standard shares and exports can store files in the root of the directory. Source :- https://portal.nutanix.com/#/page/solutions/details?targetId=TN-2041-Nutanix-Files:top_exports_and_shares.html

Quick and handy command reference for checking Nutanix Files

Nutanix Files, formerly known as AFS, is the company’s File Server and File Sharing solution on a Nutanix cluster.  By provisioning Nutanix Files within the Nutanix cluster, we have essentially eliminated the need to deploy a dedicated Network Attached Storage (NAS) solution for Windows/SMB file services.  Nutanix Files operates as a clustered, distributed File server driven by a set of File server VMs commonly referred to as FSVMs.   A customer or user new to Nutanix Files and its orchestration could feel intimidated by the plethora of possibilities and intricacies in managing the Nutanix Files infrastructure.  Let me try to help you make a start by providing you some commands to get a jumpstart in handling this product.  I will use the following conventions to differentiate between running a command at the CVM layer as against running the command inside a FSVM:nutanix@CVM:$ nutanix@FSVM:$ Here we go:  List the FSVMs and their IP addresses --- a few alternatives as well:nutanix@CVM:$

Backup and Disaster recovery in Nutanix Files

Nutanix provides a number of options for you to backup your Nutanix Files data. Following modern data protection methodologies, Nutanix provides administrators and users quick restore access using a combination of some of the following methods:   Self Service Restore:  Administrators can enable SSR at any time for SMB or NFS shares. You can view and restore removed or overwritten files, which allows you to choose a share snapshot from the same file at different times during the file’s history. Administrators can configure a snapshot schedule at the file server level that applies to all shares in the file server.     Protection Domains and Consistency Groups:  Nutanix provides integrated, automated disaster recovery between Nutanix clusters. A Nutanix Files cluster can be protected with Prism and uses the same asynchronous replication with protection domains and consistency groups as any other Nutanix cluster. When you create a file server, Prism Automatically sets up a correspon

Nutanix Files - FSVM Max Connections Notification

Nutanix Files offers SMB shares and NFS exports for file serving use-cases in enterprise environments. Not all environments are equal and every solution has some recommendations to cater for high traffic environments, where hundreds or thousands of users might be accessing a single storage endpoint or a file share concurrently. Nutanix AOS and Files offers the flexibility to scale as your requirements grow without down-time or disruption to existing operations. Connection count to existing file shares can increase, where a Nutanix Files environment is being used by more users or applications than initially anticipated at the time of deployment.  An increase in users or usage of the Nutanix Files cluster can trigger a high connection count alert as follows: FileServerVmMaxConnectionsNotification (A160039) The "Maximum Connection limit" alert is generated when the Files cluster has one or more FSVM nodes under extensive load. This alert recommends running *’Performance optimisation'. Thi

Nutanix Files: SMB Migration Guide

This guide provides an overview of best practices and considerations when migrating from third-party platforms to Nutanix Files when using the SMB protocol. We also walk through an example of how to perform a migration.   Directory Structure and Storage Requirements When migrating to Nutanix Files, first take an inventory of the share and directory structure of the source. Nutanix Files distributes ownership of file shares across the cluster in different ways depending on the share type (distributed versus standard). Note the largest single directories or largest file shares. Performance Requirements Know how many user connections a given share or a given Files namespace requires. If possible, also document any storage IOPS or throughput requirements. Most sizing exercises assume that the system uses all nodes in the Nutanix Files cluster. It is ideal, from both a user connectivity and storage performance perspective, to distribute the workload evenly across the Nutanix Files clus

Nutanix Files 3.x - Expanding File Server Storage

A Nutanix Files cluster is a single namespace that includes a collection of file systems used to support the SMB and NFS shares. These file systems use Nutanix volume groups as storage. Volume groups enable both high availability and scale-out for the file systems. A volume group is a collection of logically related vDisks (or volumes) attached to the guest via iSCSI. When an FSVM is down for maintenance or if a fault occurs, one of the surviving FSVMs takes over volume group ownership and continues servicing requests.   With the 3.x release of Nutanix Files, volume groups contain 16 virtual disks. From the 3.2 release of Files onward, all disks in the volume group are available for use by the assigned shares, representing a maximum standard share size of 140 TB.   Nutanix Files Storage The initial file system pool created on the volume group uses six of the drives as previously noted and supports 40 TB of data Once this file system pool reaches 80 percent space utilisation, Nutanix

Nutanix Files - Changing IP Addresses for Existing FSVMs

Nutanix Files Cluster comprises of multiple virtual machines or FSVMs, which require both internal (Storage) and external (Client) IP Addresses. Files Cluster with 3 x FSVMs require at least 7 IP Addresses (3 x Internal + 3 x External + One Internal IP). Storage Network ( Internal Network ) needs to reach the CVMs and the Data Services IP (for best performance they should all be in the same subnet) Client Storage (External Network ) needs to reach the Domain Controllers and Client. As of AOS 5.6 and Nutanix Files 3.x, File Server Re-IP is now a supported workflow as shown below.  The whole Re-IP workflow involves 4 steps From Prism, navigate to the File Server tab. Highlight the File Server and select "Update" --> "Network Configuration". Please remove the existing "File Server DNS entries" before changing the client network.
