3.9. 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 — Options to pass to the mkfs call for the new file system.

    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.

    File System

    Name — Create a name for the file system resource.

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

    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 — Options to pass to the mkfs call for the new file system.

    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.

    Checkboxes — Specify mount and unmount actions when a service is stopped (for example, when disabling or relocating a service):

    • Force unmount — If checked, forces the file system to unmount. The default setting is unchecked.

    • Reboot host node if unmount fails — If checked, reboots the node if unmounting this file system fails. The default setting is unchecked.

    • Check file system before mounting — If checked, causes fsck to be run on the file system before mounting it. The default setting is unchecked.

    IP Address

    IP Address — Type the IP address for the resource.

    Monitor Link checkbox — Check the box to enable or disable link status monitoring of the IP address resource

    NFS Mount

    Name — Create a symobolic name for the NFS mount.

    Mount Point — Choose the path to which the file system resource is mounted.

    Host — Specify the NFS server name.

    Export Path — NFS export on the server.

    NFS and NFS4 options — Specify NFS protocol:

    • NFS — Specifies using NFSv3 protocol. The default setting is NFS.

    • NFS4 — Specifies using NFSv4 protocol.

    Options — NFS-specific options to pass to the mkfs call for the new file system. For more information, refer to the nfs(5) man page.

    Force Unmount checkbox — If checked, forces the file system to unmount. The default setting is unchecked.

    NFS Client

    Name — Enter a name for the NFS client resource.

    Target — Enter a target for the NFS client resource. Supported targets are hostnames, IP addresses (with wild-card support), and netgroups.

    Read-Write and Read Only options — Specify the type of access rights for this NFS client resource:

    • Read-Write — Specifies that the NFS client has read-write access. The default setting is Read-Write.

    • Read Only — Specifies that the NFS client has read-only access.

    Options — Additional client access rights. For more information, refer to the exports(5) man page, General Options

    NFS Export

    Name — Enter a name for the NFS export resource.

    Script

    Name — Enter a name for the custom user script.

    File (with path) — Enter the path where this custom script is located (for example, /etc/init.d/userscript)

    Samba Service

    Name — Enter a name for the Samba server.

    Work Group — Enter the Windows workgroup name or Windows NT domain of the Samba service.

    NoteNote
     

    When creating or editing a cluster service, connect a Samba-service resource directly to the service, not to a resource within a service. That is, at the Service Management dialog box, use either Create a new resource for this service or Add a Shared Resource to this service; do not use Attach a new Private Resource to the Selection or Attach a Shared Resource to the selection.

  3. When finished, click OK.

  4. Choose File => Save to save the change to the /etc/cluster/cluster.conf configuration file.
