Chapter 8: Configure MxFS-Linux 160

Always active: If you check this box, upon server failure, the Virtual NFS

Service will move to an active server even if the associated Export Group

monitor is inactive or down. If the box is not checked, failover will not

occur when the associated monitor is inactive or down on all of the

backup servers and the Virtual NFS Service will not be made active

anywhere. (See “Virtual Host Activeness Policy” on page 215 for details.)

Policy: The policy determines the failback action that the Virtual NFS

Service will take following a failover to a backup node.

•

AUTOFAILBACK. This policy is intended to return the Virtual NFS

Service to its original configuration, or as close to it as possible, when

the primary node is returned to service. After the Virtual NFS Service

fails over to a backup node, Matrix Server watches the health of the

nodes that are higher in the list of servers configured for that Virtual

NFS Service. When the health of one of these nodes is equal to or greater

than the backup node where the Virtual NFS Service currently resides,

the Virtual NFS Service will automatically attempt to fail over to that

node.

•

NOFAILBACK. This policy is intended to minimize failovers. The

Virtual NFS Service remains active on the backup node, even after the

primary node is returned to service, until a “healthier” node becomes

available, at which point the Virtual NFS Service fails over to that

node. (On a “healthier” node, more of the services associated with the

Virtual NFS Service will be up than on the node currently hosting the

Virtual NFS Service.)

Network Interfaces Available/Configured: Move the interfaces on which

the Virtual NFS Service should be configured from the Available column

to the Configured column. The first interface that you select is the

primary interface. The other interfaces that you select are backups. You

can use the up and down arrows to reorder the interfaces on the

Configured column.

The Virtual NFS Service appears on the Servers, Virtual Hosts, and

Applications tabs on the Management Console. Following is the Virtual

Hosts view.
