CloudBees Replication Parent 2188

Previously, in a CloudBees CI on traditional platforms controller, the CloudBees Replication plugin (cloudbees-replication) would indicate it was ready immediately after installation. However, the plugin requires a controller restart for the High Availability (HA) functionalities and the user interface (UI) to function fully.

In a CloudBees CI on traditional platforms High Availability (HA) controller, replicas would generate warning logs related to file creation because the JENKINS_HOME directory was not yet created. This was due to the warhead code executing before the core created the JENKINS_HOME directory. Now, the warhead code creates the home directory if it is missing, resolving the issue.
