7. Adding Cluster Resources
To specify a device for a cluster service, follow these steps:
1. On the Resources property of the Cluster Configuration Tool, click the Create a Resource
button. Clicking the Create a Resource button causes the Resource Configuration dialog
box to be displayed.
2. At the Resource Configuration dialog box, under Select a Resource Type, click the
drop-down box. At the drop-down box, select a resource to configure. The resource options
are described as follows:
GFS
Name — Create a name for the file system resource.
Mount Point — Choose the path to which the file system resource is mounted.
Device — Specify the device file associated with the file system resource.
Options — Mount options.
File System ID — When creating a new file system resource, you can leave this field blank.
Leaving the field blank causes a file system ID to be assigned automatically after you click
OK at the Resource Configuration dialog box. If you need to assign a file system ID
explicitly, specify it in this field.
Force Unmount checkbox — If checked, forces the file system to unmount. The default
setting is unchecked. Force Unmount kills all processes using the mount point to free up
the mount when it tries to unmount. With GFS resources, the mount point is not unmounted
at service tear-down unless this box is checked.

Name — Create a name for the file system resource.
File System Type — Choose the file system for the resource using the drop-down menu.
