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).

On the host to be removed, stop the cluster:
```
service heartbeat stop
```
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
```

Note

This procedure only works for pacemaker versions after 1.1.8.
