Cloned from http://devel.opensaf.org/ticket/1766
Some text in the original ticket description is questionable. But, migrating
this ticket for reference. This ticket has also to be read in parallel with
https://sourceforge.net/p/opensaf/tickets/220/.
The current OpenSAF cluster management takes a fairly minimalistic approach in
that it only requires that a node have connectivity to the current active
controller and there is no active health monitoring performed of the current
member cluster nodes.
The purpose of this enhancement is to propose enhancing the OpenSAF cluster
management/membership approach to:
- Ensure a prospective node has network connectivity to all current cluster
members
- Perform minimal health monitoring of cluster node members to detect fault
conditions not currently detected with today's approach
- Better handle split-brain conditions

Full mesh connectivity determination and quorum based indication for enhanced
cluster 'management' should either come in as a new service/layer and/or
eventually as an enhanced NODE_UP/NODE_DOWN message into CLM, thus keeping
intact the current mechanism to feed CLM with connection evidences.
