Installation guide

Note

To verify the existence of the IP service resource used in a cluster service, you

must use the /sbin/ip addr list command on a cluster node. The following

output shows the /sbin/ip addr list command executed on a node running a

cluster service:

1: lo: <LOOPBACK,UP> mtu 16436 qdisc noqueue

link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00

inet 127.0.0.1/8 scope host lo

inet6 ::1/128 scope host

9. Propagating The Configuration File: New Cluster

For newly defined clusters, you must propagate the configuration file to the cluster nodes as

follows:

1. Log in to the node where you created the configuration file.

2. Using the scp command, copy the /etc/cluster/cluster.conf file to all nodes in the

cluster.

Note

Propagating the cluster configuration file this way is necessary for the first time a

cluster is created. Once a cluster is installed and running, the cluster

configuration file is propagated using the Red Hat cluster management GUI

Send to Cluster button. For more information about propagating the cluster

configuration using the GUI Send to Cluster button, refer to Section 3,

“Modifying the Cluster Configuration”.

10. Starting the Cluster Software

After you have propagated the cluster configuration to the cluster nodes you can either reboot
