SunPlex Manager installs Sun Cluster HA for Network File System (NFS) by setting up a basic configuration that uses one exported directory. You must configure Sun Cluster HA for NFS as a failover service.
After the Sun Cluster HA for NFS installation is complete, you can customize the configuration by modifying, adding, and removing the exported directories.
Note: Multiple instances of Sun Cluster HA for NFS can
run on the cluster if the following conditions are met:
For more information about how to customize your Sun Cluster HA for NFS installation, follow the procedures in the Sun Cluster documentation set.
Before you install Sun Cluster HA for NFS, perform the following tasks:
Note: The Sun Cluster HA for NFS takes approximately 10 minutes to install.
If you exit SunPlex Manager or click the Back button in your web browser after you begin the installation, you are disconnected from the installation. This disconnection can result in an incomplete installation because of insufficient information or an unresolved error message.
To clean up an incomplete installation, you must remove the
application files and the resources and resource groups that were
created.
The following table describes the information you provide during installation:
Field | Description |
---|---|
Export Directory | The global directory that is exported. |
Path Prefix | The directory that holds the configuration files. |
Resource Name | The name of the Sun Cluster HA for NFS resource that is created. This name must be unique within the cluster. |
Network Resource | The logical host name that is used to access NFS over the network. |
You can modify the Sun Cluster HA for NFS by:
Note: The share_nfs(1M) man page provides additional information about how to modify the Sun Cluster HA for NFS configuration.
Field | Description |
---|---|
Exported Directory | The path for the exported directory. |
Access Options | The type of access that is permitted (rw = read and write, ro = read only). |
Description | The description of the exported directory. |
Action | Whether or not the directory is exported. |
Note: Do not remove all directories from the export list, because a Sun Cluster HA for NFS resource must export at least one directory. If you want to stop exporting all directories, take the resource offline, delete the resource, or do both.
