I have a question regarding a split brain scenario with a SWIM based algorithm that SERF implements.
Let's assume the following situation:
The cluster contains of 8 member nodes.
Let's say one link goes down an the connection between 2 sites is split up - the cluster is divided into two halfs without connectivity to each other.
After some time the link that went down between the 2 halfs is back up again.
How can such a situation be resolved with SERF? Is it possible to reach convergence again (forming a single cluster again) by i.e. probing one of the other members from time to time?
Do you have any suggestions?
Thank you! and BR
