Adding a Database or Cluster Node

You can use options on the Actions drop-down menu (located in the upper-right corner of the Cloud console) to add a database to a node or a node to a cluster. The menu options are context-sensitive, applying to the object currently selected in the navigation panel. To access menu options, select the name of the cluster or database you'd like to modify in the navigation panel, and then open the Actions menu.

Adding a Node to a Cluster

To add a node to an existing cluster, select the cluster name in the navigation panel, open the Actions menu, and select Add Nodes.

When the Add Node dialog opens, provide details the new node(s):

• Use indicators on the map or select regions from the drop-down list in the Select regions field to choose the region(s) in which the new nodes will reside.
• Accept the Default configuration to use server-assigned network addresses or select Manual to assign specific addresses for your new node(s).
• Network addresses for the new node(s) are assigned for consistency with the rest of your cluster, and are not modifiable.
• The Instance Type field displays the value selected for the other nodes in your cluster; use the selector to choose an alternative configuration. If you are adding more than one node in a single update, the same configuration will be applied to both nodes.
• The Volume Size field displays the data volume size of the other nodes in your cluster; use the selector to choose an alternative size. If you are adding more than one node in a single update, the same size will be applied to both nodes.

After specifying your preferences, select the Add Nodes button to deploy your new nodes and add them to your cluster. The cluster will be placed in modification status until the addition is complete; when the update finished, you will be able to access the new node using the SSH configuration defined during the initial cluster creation.

Adding a Database to a Cluster Node

To add a database to a cluster node, select the database name in the navigation panel, open the Actions menu, and select Add to Nodes. Note that node must be an operational member of the cluster before you can add a database to the node. The node to which you are adding the database must be a member of the cluster on which the database was created.

When you add a database to a node, Cloud uses Spock's Zodan functionality to copy the existing data to the new node. Automatic DDL replication is enabled as the node joins the cluster.

The Add Database... to Cluster Nodes dialog opens as shown below:

On the map, nodes connected by a dotted line are currently replicating the selected database amongst themselves. Nodes that are not attached to other nodes by a dotted line are currently not hosting the selected database. To select a node(s) for updating, click in the Regions field to access a list of available nodes on which the database does not currently reside, or click a node(s) on the map.

After selecting the node(s), click the Add Nodes button to start the modification process.
