12 Customizing Your Cluster : 12.1 Adding an Extension to a New Cluster

An administrative user can use the Optional Node Packages field on the Add Engine or Edit Engine dialog to modify a database engine definition, providing the names of optional rpm packages that will be installed (from the specified repository) during provisioning. All engines created with that definition will contain the new component; the component will be provisioned on each replica as well as on the master node. As each rpm is installed, yum will satisfy the dependencies for the new component.
Packages added via the Optional Node Packages field on the master node of the cluster will be provisioned on any standby nodes that are subsequently created. If the package requires manual configuration steps, you will be required to repeat those steps on each node of the cluster; package configurations will not be propagated to standby nodes. If you add a node through cluster operations (such as failover, scaling, or restoring a node from backup), any packages on the new node will also require manual configuration.
