Removing a node from a cluster

This section describes how to remove a node from a cluster. As in previous
examples, the following removes the system system03 from a three-node
cluster. The procedure can be done from any node remaining in the cluster or
from a remote host.

To remove a node from a cluster

1

Log in as superuser on a node other than system03.

2

Stop all the cluster components:

# cfscluster stop -f system03

3

Open the VCS configuration for writing:

# haconf -makerw
