Configuring the Cluster

Distributing the Binary Configuration File

After specifying all cluster parameters, you apply the configuration. This

action distributes the binary configuration file to all the nodes in the

cluster. We recommend doing this separately before you configure

packages (described in the next chapter). In this way, you can verify the

cluster lock, heartbeat networks, and other cluster-level operations by

using the cmviewcl command on the running cluster. Before distributing

the configuration, ensure that your security files permit copying among

the cluster nodes. See “Preparing Your Systems” at the beginning of this

chapter.

Distributing the Binary File on the Command Line

Use the following steps to generate the binary configuration file and

distribute the configuration to all nodes in the cluster:

• Activate the cluster lock volume group so that the lock disk can be

initialized:

# vgchange -a y /dev/vglock

• Generate the binary configuration file and distribute it:

# cmapplyconf -k -v -C /etc/cmcluster/clust1.config

# cmapplyconf -k -v -C /etc/cmcluster/clust1.ascii

NOTE Using the -k option means that cmapplyconf only checks disk

connectivity to the LVM disks that are identified in the ASCII file.

Omitting the -k option (the default behavior) means that

cmapplyconf tests the connectivity of all LVM disks on all nodes.

Using -k can result in significantly faster operation of the command.

• Deactivate the cluster lock volume group.

# vgchange -a n /dev/vglock
