5.9. 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

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 cman start
2. 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.
3. service gfs start, if you are using Red Hat GFS
