7 After the initial configuration is done, you need to transfer the configuration to
the other nodes in the cluster. The easiest way to do so is to copy the
/etc/

to have a unique node ID, make sure to adjust the node ID accordingly after

If you want to use encrypted communication, also copy the
/etc/ais/
authkey
to the other nodes in the cluster.

rcopenais start
2 On one of the nodes, check the cluster status with the following command:
crm_mon
