Postgres as a Service
Deploy a Managed Postgres Cluster in Minutes! Enterprise-ready and Oracle compatible.
You can add a node to a Failover Manager cluster at any time. To be a useful Standby for the current node, the node must be a standby in the PostgreSQL Streaming Replication scenario.
1. Assume the identity of efm or the OS superuser on any existing node (that is currently part of the running cluster), and invoke the efm add-node command, adding the IP address of the new node to the Failover Manager Allowed node host list.When invoking the command, specify the cluster name, the IP address of the new node, and if applicable, the failover priority of the new node:efm add-node cluster_name ip_address [priority]For more information about using the efm add-node command or controlling a Failover Manager service, see .
4. Assume superuser privileges on the new node, and use the service efm-2.0 start command to start the Failover Manager agent:When the new node joins the cluster, Failover Manager will send a notification to the administrator email provided in the user.email parameter in the cluster properties file.
