Configuring an NFS Cluster Service

This chapter provides the procedure for configuring an NFS service in a Red Hat Cluster Suite.
In order to configure an NFS service for a GFS file system in a cluster, you need to perform the
following steps:
• Add a service to the cluster and provide a name for the service, as described in
Service to the Cluster".
• Add an IP address resource to service, as described in
Resource to an NFS
• Add a GFS resource to the service, as described in
NFS Service".
• Add an NFS export resource to the service, as described in
Resource to an NFS
• Add the NFS client resources to the services, as described in
Resources to an NFS
Some Red Hat Cluster resources must be configured as parent or child resources in a service. A
resource that is configured as a parent resource is started before the children of that resource are
started. All resources that are configured as a child resources of a parent must stop cleanly before
a parent resource may be stopped. For a resource that is configured as a parent resource to be
considered in good health, all the resources configured as its child resources must be in good health.
When you configure the NFS export resource for an NFS service, you must configure it as a child of
the GFS resource. You must configure each NFS client resource for an NFS service as a child of the
NFS export resource.

5.1. Add a Service to the Cluster

To add a service to your cluster using Conga, perform the following procedure:
1. As an administrator of luci Select the cluster tab.
2. From the Choose a cluster to administer screen, select the cluster to which you will add
resources. In this example, that is the cluster with the name nfsclust.
3. At the menu for cluster nfsclust (below the clusters menu), click Services. This causes the
display of menu items for service configuration: Add a Service and Configure a Service.
4. Click Add a Service. Clicking Add a Service causes the Add a Service page to be displayed.
5. For Name, enter nfssvc.
6. Leave the checkbox labeled Automatically start this service checked, which is the default
setting. When the checkbox is checked, the service is started automatically when a cluster is
started and running. If the checkbox is not checked, the service must be started manually any time
the cluster comes up from the stopped state.
