4.5.2. 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 complete solution. First, one must arrange for Heartbeat to forget about the node (pcmk-1 in the example below).
  1. On the host to be removed, stop the cluster:
    service heartbeat stop
  2. From one of the remaining active cluster nodes, tell Heartbeat the node should be removed:
    hb_delnode pcmk-1
  3. Tell Pacemaker to forget about the removed host:
    crm_node -R pcmk-1


This procedure only works for pacemaker versions after 1.1.8.
