3.1.2 MxFS-Linux Administration Guide

Configure Virtual NFS Services

A Virtual NFS Service exports the PSFS filesystems specified in its

associated Export Group. Clients access the filesystems via the

hostname/IP address of the Virtual NFS Service instead of using the

hostname/IP address of the physical node.

To create a Virtual NFS Service, you will need to specify the nodes on

which the Virtual NFS Service should be configured. Optionally, you can

also specify the Export Group that should be exported by the Virtual NFS

Service. (You can also associate a Virtual NFS Service with an Export

Group when you create the Export Group.)

Overview

Sample Configurations

Following are some examples of configurations using MxFS to provide

NFS services.

Active-Active Failover Configuration

In an active-active configuration, all nodes in the matrix may act as a

primary for one or more Virtual NFS Services and as a backup for other

Virtual NFS Services. If an Export Group monitor reports a failure on a

particular node, MxFS may fail over Virtual NFS Services from that node

to a backup node. Clients then continue to access the Virtual NFS Services

via the same IP address from the backup node without downtime or

disconnection. Because the files associated with the NFS Service are
