Installation guide

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 6.3, “Modifying the Cluster Configuration”.

5.10. Starting the Cluster Software

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:

1. service ccsd start

2. service cman start (or service lock_gulm d start for GULM clusters)

3. service fenced start (DLM clusters only)

4. service clvmd start, if CLVM has been used to create clustered volumes

Note

Shared storage for use in Red Hat Cluster Suite requires that you be running the cluster

logical volume manager daemon (clvmd) or the High Availability Logical Volume

Management agents (HA-LVM). If you are not able to use either the clvmd daemon or HA-

LVM for operational reasons or because you do not have the correct entitlements, you must

not use single-instance LVM on the shared disk as this may result in data corruption. If you

have any concerns please contact your Red Hat service representative.

5. service gfs start, if you are using Red Hat GFS

6. service rgm anager start, if the cluster is running high-availability services (rgm anager)

7. Start the Red Hat Cluster Suite management GUI. At 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.
