how to migate a Akka cluster without stopping service

I started a ODL(opendaylight) cluster with the following akka config: enter image description here

So, the nodes(11.128.83.43, 11.128.83.33, 11.128.83.32) make up a cluster， 11.128.83.43 is member-1, 11.128.83.33 is member-2 and 11.128.83.32 is member-3. these days I want to expand two nodes(11.128.83.41, 11.128.83.48) into the cluster, so i'm wandering if the akka will allow me to update and reload the config without shutdown the cluster service?

I searched some akka docs, there is no related anwser

Solution

  • The existing nodes do not need to be shutdown: it should be sufficient to configure the new nodes to use at least one of the existing nodes as a seed node.
