Symptoms

One simple definition of the "split-brain" condition is a condition whereby two or more instances of the same cluster are running. A split-brain condition would allow each cluster instance to access cluster resources without knowledge of the other cluster instance, resulting in corrupted cluster integrity.

In this specific scenario a split brain situation has arisen in a two-node cluster.  Node two shows a different list of components than node one.  This is shown by running opmnctl status on both nodes and comparing the results.
