3.5.1 Matrix Server Administration Guide

Configure MxFS-Linux

Matrix Server and MxFS-Linux provide scalability and high availability

for the Network File System (NFS), which is commonly used on

UNIX and

Linux systems to share files remotely.

Overview

MxFS-Linux Concepts and Definitions

MxFS-Linux uses and manages the following objects to provide scalable

and highly available file service across the cluster: Export Groups, export

records, and Virtual NFS Services.

Export Groups

An Export Group is equivalent in form and function to the /etc/exports file

of a traditional NFS server. However, unlike a traditional NFS server,

MxFS-Linux supports multiple Export Groups (the equivalent of multiple

independent /etc/exports files) on a single node.

An Export Group is composed of a name (which must be unique among

all other Export Groups in the cluster), a list of cluster nodes that will

participate in the NFS service for the exports defined by this Export

Group, and a list of Export Records describing the filesystems shared via

NFS by the nodes listed in the Export Group. An Export Group created

on one node of the cluster is immediately available to all cluster nodes

defined in the Export Group.

High-availability monitors are provided to watch the health of the NFS

service and vital MxFS-Linux processes and to check whether the
