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
Note
Shared storage for use in Red Hat Cluster Suite requires that you be running the
cluster logical volume manager daemon (
Volume Management agents (HA-LVM). If you are not able to use either the
daemon or HA-LVM for operational reasons or because you do not have
clvmd
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.
