Remove nodes from the cluster

To remove nodes from a cluster, run the update_vertica script and specify:

• The option --remove-hosts, followed by the IP addresses of the nodes you are removing.

• The option --ssh-identity, followed by the location and name of your *pem file.

• The option --dba-user-password-disabled.

The following example removes one node from the cluster:

$ sudo /opt/vertica/sbin/update_vertica  --remove-hosts 10.0.11.165  --point-to-point  \
  --ssh-identity ~/name-of-pem.pem --dba-user-password-disabled
