   You are right, I missed that we use node id as raft peer id in OM, and which is now already shown..
   
   Lets not go the route of peerID unification, as if we want to do we need to consider fresh/old installation.
   
   Where in fresh installations we can generate UUIDS, and old we should we should have as it is.
