+ Removing nodes with crm cluster remove

+ You can remove nodes from the cluster with the crm cluster remove
+ bootstrap script.

+
+ If you run crm cluster remove with no additional parameters, you are

+ specify the node when you run the command:
+
+&prompt.root;crm cluster remove NODE
+
+ On the specified node, this stops all cluster services and removes the local cluster
+ configuration files. On the rest of the cluster nodes, the specified node is removed
+ from the cluster configuration.
+
+
+ In most cases, you must run crm cluster remove from a different node,
+ not from the node you want to remove. However, to remove the last node
+ and delete the cluster, you can use (or ):
+
+&prompt.root;crm cluster remove --force LASTNODE
+
+ For more information, run crm cluster help remove.
