Installation guide

b. Select the cluster node to be deleted. At the bottom of the right frame (labeled Properties),
click the Delete Node button.
c. Clicking the Delete Node button causes a warning dialog box to be displayed requesting
confirmation of the deletion (Figure 5.9, “Confirm Deleting a Member”).
Figure 5.9. Confirm Deleting a Member
d. At that dialog box, click Yes to confirm deletion.
5. Propagate the configuration file to the cluster nodes as follows:
a. Log in to the node where you created the configuration file (the same node used for running
system-config-cluster).
b. 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 under these
circumstances because the cluster software is not running, and therefore not
capable of propagating the configuration. 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 6.3,
“Modifying the Cluster Configuration”.
c. After you have propagated the cluster configuration to the cluster nodes you can either
reboot each node or start the cluster software on each cluster node by running the following
commands at each node in this order:
a. service ccsd start
b. service lock_gulm d start
c. service clvm d start, if CLVM has been used to create clustered volumes
d. service gfs start, if you are using Red Hat GFS
e. service rgm anager start, if the node is also functioning as a GULM client and
the cluster is running cluster services (rgm anager)
d. At system-config-cluster (running on a node that was not deleted), in the Cluster
Configurat ion T ool tab, verify that the configuration is correct. At the Cluster Status
Tool tab verify that the nodes and services are running as expected.
