Configuration Synchronization Wizard Menu
=========================================
(1) Set up a cfengine master server
(2) Add a client
(3) Remove a client
(4) Manage keys for cfengine clients
(5) Display current configuration
(9) Exit
Enter choice: 1
After you choose 1 and press Enter, the wizard displays the following text:
This system is a member of a Serviceguard cluster. The cfengine
configuration will be defined as a package for high availability
unless you answer no to the question below. If you answer no, for the
purposes of cfengine control, this machine will be treated as a single
machine without failover capability for cfengine.
If you accept the default answer of ‘HA’ to the question below,
cfengine will be configured as a highly available Serviceguard package.
This ensures that your cfengine master server is available as long
as one of the cluster members that can run the package is also available.
You will need a free IP address for this package and you must
configure storage for the package before proceeding. For details
on creating highly available file systems, please refer to the
Managing Serviceguard manual.
Will this master server be Highly Available (HA) [Y]:
The wizard names the package name “csync” for configuration synchronization. This specific
package name is required. The LVM storage configuration and network configuration for the
package must be set up before continuing or before running the wizard. All the cluster members
should also be up and available. For details, refer to the Managing Serviceguard manual, under
“Building an HA Cluster Configuration”, “Creating a Storage Infrastructure with LVM.”
NOTE: The wizard only supports creating packages based on LVM volume groups. When
using CFS or VxVM, manual configuration is required. See the section on “Manually Configuring
a Serviceguard Cluster Synchronization Server” (page 32) for details on manually configuring
the csync package.
The wizard prompts for the following, all of which should have already been configured:
• LVM volume group name (for example, /dev/vgcsync)
• Logical volume in the volume group; must be the full path name of the logical volume (for
example, /dev/vgcsync/lvol1)
• The filesystem mount point (for example, /csync)
• The filesystem mount options (for example, -o rw). The mount options are used verbatim
in the Service package control script’s FS_MOUNT_OPT[0] field. Note that the mount options
must agree with the filesystem you created on the logical volume.
• The filesystem type (for example, ext3)
• The package IP address. This should also be a registered DNS name so the configuration
synchronization is easy to configure on client systems.
• The package subnet. (Use netstat -i to determine the correct subnet.)
