3 Use Cases : 3.2 EDB Failover Manager (EFM) Functions

For using EFM, ensure that the enableHAMode property is set to Yes in the database section of the values yaml file.
Note: EFM is enabled by default on the EPAS containers.
Optionally, the pgPool pods can serve as witness nodes by setting the enableHAMode property in the queryrouter section of the values yaml file.
Note: EFM is disabled by default on pgPool containers.
For EFM to function properly, the replicas property in the database section has to be at least 3 i.e., 1 master and 2 standbys.
To customize EFM settings, create a file named efm.properties.in and include it in the configmap volume edb1-initconf-vol by placing it in the initconf directory prior to creating the configmap volume.
Note: The master node is edb1-as-0.
Note: Node 10.48.1.97 (edb1-as-1) has transitioned from standby to master, and the newly created node 10.48.2.97 (edb-as-0) is the new standby.
Note: The new master is 10.48.0.40 (edb1-as-2) and the previous master 10.48.1.97 (edba-as-1) is now a standby node.
