Hi Gary, Have query regarding quorum selection when raft servers are external to the OpenSAF Cluster
In the document we are saying "The consensus service uses quorum to prevent state changes in network partitions that don't include more than half of the nodes in the cluster" => This is possible if the raft server is installed on the OpenSAF Cluster Nodes, as Raft decides which partition has more no of nodes. but in the case where raft servers run on external nodes outside of the OpenSAF Cluster, how the quorum is decided => If the Raft Servers are external to OpenSAF Cluster, do we need to make any configuration so that etcd client on the OpenSAF nodes communicates with Raft Leader Also it will be good if we give some details about how to install and configure raft(raft servers within and external to the opensaf cluster) Thanks, Ravi -----Original Message----- From: Gary Lee [mailto:gary....@dektech.com.au] Sent: Friday, January 26, 2018 11:28 AM To: Hans Nordebäck <hans.nordeb...@ericsson.com>; Anders Widell <anders.wid...@ericsson.com>; Ravi Sekhar Reddy Konda <ravisekhar.ko...@oracle.com> Cc: opensaf-devel@lists.sourceforge.net Subject: Review Request for doc: update overview PR for split brain prevention with consensus service [#64] Hi I have updated the OpenSAF Overview PR document for ticket #64.
