How to Remove All DNS Cluster Servers in cPanel

Sometimes WHM (Clusters → DNS Cluster) shows old or unwanted cluster servers.
If you want to remove them all from the command line, follow these steps:

1. Backup Current Cluster Config (optional but recommended)

cp -r /var/cpanel/cluster/root/config /root/cluster_backup

This creates a backup at /root/cluster_backup.

2. Remove All Cluster Entries

rm -f /var/cpanel/cluster/root/config/*

This deletes all cached DNS cluster configuration files.

 

3. Restart cPanel/WHM

service cpanel restart

(or on systemd servers:)

systemctl restart cpanel

Verification

Log into WHM → Clusters → DNS Cluster.
It should now display:

There are currently no servers in your DNS cluster.
