Adding Conductor redundancy to an existing cluster
You might have originally deployed the cluster with only one AWS Elemental Conductor Live node. You might now want to add a secondary Conductor Live node, to implement node redundancy on the Conductor nodes.
Perform the following steps in the specified order:
-
As your first step, you should identify your redundancy requirements. See Designing the cluster.
-
Verify the firewall setup is the primary Conductor Live:
-
Make sure that the firewall is enabled on both Conductor Live nodes.
-
Accept port 5432 TCP.
-
-
Configure the secondary Conductor Live, perform the following tasks. Perform these tasks in any order:
-
Configure Ethernet interfaces and bonds (optional).
-
Enable HTTPS on the node..
-
Configure NTP servers.
You don't need to configure as many fields on the secondary Conductor Live because the secondary Conductor Live will synchronize with the primary Conductor Live.
-
Recruit (add) the secondary Conductor Live into the existing cluster.
-
Create a redundancy group for the two Conductor Live nodes, and add the nodes to that group. See Creating a Conductor Live redundancy group.
-
Enable HA (high availability) on the primary Conductor Live. When you enable HA, the secondary Conductor Live synchronizes itself with the primary Conductor Live.
