Enabling DNS clustering on each server
A DNS cluster is a number of nameservers that share records. To optimally configure your DNS cluster, you will need 2 spare servers, both preferably running cPanel DNS ONLY. You will also need at least 1 web server with cPanel/WHM installed.
You can download the cPanel DNS ONLY software here.
http://layer1.cpanel.net/cpanel-dnsonly-install.sea
All machines in the cluster must be running cPanel or cPanel DNS ONLY version 11 or higher. Some features may not work with older versions of cPanel.
Enabling DNS clustering on each server
First, you will need to enable DNS clustering via each server’s WHM interface.
1. Navigate to WHM’s Configure Cluster screen.
2. Click Enable Dns Clustering.
3. Click Change.
4. Click Return to Cluster Status.
Next, you will need to specify which server(s) you wish to cluster, or share DNS information with.
You do not need to link dedicated DNS servers to each other, or link dedicated web servers to each other.
You will need to sync each web server to its DNS servers.
You should not set a DNS server to sync data back to a web server, as this will put extraneous data on the web server.
Enabling the additional Plesk add-on
There are many feature that can be added on to your Plesk install such as Help Desk, Dr. Web, etc… these features are not available in the default install, but you can easily activate then by buying them from parallels.com.
1. Log into Plesk
2. Click “Server” on the left hand side
3. Click the “License Management” icon
4. Click the “Order Control Panel Add-Ons” icon
Enabling DNS clustering on cpanel server

You do not need to link dedicated DNS servers to each other, or link dedicated web servers to each other.
You should not set a DNS server to sync data back to a web server, as this will put extraneous data on the web server.
Steps:
1. Navigate to WHM’s Configure Cluster screen.
2. Click Enable Dns Clustering.
3. Click Change.
4. Click Return to Cluster Status.
DNS clustering is now enabled. Next, you will need to specify which server(s) you wish to cluster, or share DNS information with.
Enabling User/Group Quota for virtual private server that already exists.
If the virtual private server already exists, run the following command to set the parameter:
vzctl set 101 –quotaugidlimit 150 –save
Where, 101 is the VPS ID number.
Restart the virtual private server.
Enabling User/Group Quota on a Virtual Private Server (VPS)
To enable user/group quota on a virtual private server:
Edit the configuration file to set the parameter QUOTAUGIDLIMIT that controls the second-level disk quota. The two instances when you can set the parameter is:
If you are setting the parameter before the creation of the virtual private server:
Go to the location of the virtual private server configuration file. /etc/sysconfig/vz-scripts
To enable disk quota set the value of QUOTAUGIDLIMIT to a positive value, in the configuration file. For example: QUOTAUGIDLIMIT=”150″
The default value of the parameter is zero. Setting the value of the parameter to zero disables user/group quotas.
Note: Ensure that you use this configuration file when creating the virtual private server.
