3.5.1 Matrix Server Administration Guide

Chapter 8: Configure MxFS-Linux 148

The Probe Severity setting works with the Virtual NFS Service policy

(either

AUTOFAILBACK or NOFAILBACK) to determine what happens

when a monitor probe fails.

The default policies (

AUTOFAILBACK for the Virtual NFS Service and

AUTORECOVER for the Export Group monitor) cause Matrix Server to fail

over the associated Virtual NFS Services to a backup network interface on

another node when the monitor probe fails. When the original node is

again available, Matrix Server fails back the Virtual NFS Services to the

network interfaces on the original node.

You can use the Probe Severity attribute to change this behavior. There

are three settings for Probe Severity:

NOFAILOVER, AUTORECOVER, and

NOAUTORECOVER.

NOFAILOVER. The Virtual NFS Services do not fail over when the

monitor probe is DOWN. Administrative intervention is required to fail

over the Virtual NFS Services.
