Global Cluster Options

Global Cluster Options

The Failure threshold for cluster members setting allows you to specify the number of dnsadmin commands that may fail before WHM disables an unresponsive DNS cluster member.

Notes:

• We recommend that you disable unresponsive DNS cluster members in order to improve the performance of your server.
• You must enable DNS clustering in order to view the Global Cluster Options section of this interface.

To configure the Failure threshold for cluster members setting, perform the following steps:

1. Select an option from the Global Cluster Options section:

   • Select 10 (Default) to use the default option, which allows cluster members to fail up to ten dnsadmin commands.

     Note:

     We recommend that you use this option.

      

   • Select the second option to enter a custom failure threshold.

     Note:

     If server down times or network interruptions are common in your hosting environment, we recommend that you increase the failure number count so that the system does not mark certain cluster members as offline. This may also increase server and network load because the system may repeatedly send some DNS requests.  

      

   • Select Keep all cluster members online at all times if you wish to keep all of the servers in your DNS cluster continuously online, regardless of the number of failed dnsadmin commands.

2. If you wish for WHM to notify you when it disables an unresponsive member in your DNS cluster, select Receive a notification when WHM disables an unresponsive cluster member.

   Important:

   You must manually reenable a disabled cluster member.

    

3. Click Change. A confirmation message will display.
4. Click Return to Cluster Status.

Important:

If a cluster member in the sync role is offline for an extended period of time, resynchronize the other server's zones. This ensures that the cluster member is up-to-date.
