4.6.2. Removing a Heartbeat Node
Because the messaging and membership layers are the authoritative source for cluster nodes, deleting them from the CIB is not a reliable solution.
First one must arrange for Heartbeat to forget about the node (pcmk-1 in the example below).
On the host to be removed:
Stop the cluster: /etc/init.d/corosync stop
Next, from one of the remaining active cluster nodes:
Tell Heartbeat the node should be removed
# hb_delnode pcmk-1
Tell Pacemaker to forget about the removed host:
# crm_node -R pcmk-1
This proceedure only works for versions after 1.1.8
