@ -854,6 +854,16 @@ private[cluster] final class ClusterCoreDaemon(environment: ClusterEnvironment)
* When at least one reply has been received it stops itself after
* an idle SeedNodeTimeout.
*
* The seed nodes can be started in any order, but they will not be "active",
* until they have been able to join another seed node (seed1).
* They will retry the join procedure.
* So one possible startup scenario is:
* 1. seed2 started, but doesn't get any ack from seed1 or seed3
* 2. seed3 started, doesn't get any ack from seed1 or seed3 (seed2 doesn't reply)
* 3. seed1 is started and joins itself
* 4. seed2 retries the join procedure and gets an ack from seed1, and then joins to seed1
* 5. seed3 retries the join procedure and gets acks from seed2 first, and then joins to seed2
