Normally this is run from a different node in the cluster.
However, If you need to remove the current node's cluster configuration, you can run from the current node using <ip address or hostname of current node> with the "-F" option to force remove the current node.
# ha-cluster-remove -F <ip address or hostname>
In addition to remove the node clearly from cluster, the following files are deleted from the node:
csync2 configuration files.
corosync configuration file.
SBD fencing configuration.
This logic has also been added to the crm shell and can be run using the following commands.
# crm cluster init
# crm cluster join
# crm cluster remove
