This chapter describes the steps to install and configure Oracle Solaris Cluster HA for Network File System (NFS) on your Oracle Solaris Cluster nodes.
Note - If you are using the Solaris 10 OS, install and configure this data service to run only in the global zone. At publication of this document, this data service is not supported in non-global zones. For updated information about supported configurations of this data service, contact your Oracle service representative.
This chapter contains the following sections.
You must configure Oracle Solaris Cluster HA for NFS as a failover data service. See Chapter 1, Planning for Oracle Solaris Cluster Data Services, in Oracle Solaris Cluster Data Services Planning and Administration Guide and the Oracle Solaris Cluster Concepts Guide document for general information about data services, resource groups, resources, and other related topics.
Note - You can use the Oracle Solaris Cluster Manager to install and configure this data service. See the Oracle Solaris Cluster Manager online help for details.
Use the worksheets in Configuration Worksheets in Oracle Solaris Cluster Data Services Planning and Administration Guide to plan your resources and resource groups before you install and configure Oracle Solaris Cluster HA for NFS.
The NFS mount points that are placed under the control of the data service must be the same on all of the nodes that can master the disk device group that contains those file systems.
Oracle Solaris Cluster HA for NFS requires that all NFS client mounts be “hard” mounts.
No Oracle Solaris Cluster node may be an NFS client of a file system that is exported by Oracle Solaris Cluster HA for NFS and is being mastered on a node in the same cluster. Such cross-mounting of Oracle Solaris Cluster HA for NFS is prohibited. Use the cluster file system to share files among cluster nodes.
If Solaris Resource Manager is used to manage system resources allocated to NFS on a cluster, all Oracle Solaris Cluster HA for NFS resources which can fail over to a common cluster node must have the same Solaris Resource Manager project ID. This project ID is set with the Resource_project_name resource property.
 | Caution - If you use Veritas Volume Manager (available for use in SPARC based clusters only), you can avoid “stale file handle” errors on the client during NFS failover. Ensure that the vxio driver has identical pseudo-device major numbers on all of the cluster nodes. You can find this number in the /etc/name_to_major file after you complete the installation. |
