      Description

       

      Hi Team,

      we have 6 nodes replica set
      1. 3 nodes in one geographic location say Location 1 .
      2. 3 other non votable members different geographic location for the purpose of Disaster Recovery say Location 2.

      Problem:

      Whenever there was a network glitch or latency between these geographic locations , we see that the DR nodes on Location 2 are unable to reach the other 3 nodes on Location 1 and vice versa from the logs
      saying "unable to reach the host ip address / time out" .

       

      The problem is
      1. when we do rs.status () from the Node 1 , Primary from Location 1 , it shows the "up times" of all the DR nodes on Location 2 say 1600s.

      2. when we do rs.status () from the Node 4 , secondary from Location 2 , it shows the "up times" of all the Primary nodes on Location 1 say 1600s.

      Actually all the nodes are up and running more than a year with out any downtime. The Question is why the "UPTIMES" is shown different , when rs.status is evaluated from 2 different geo locations , when none of the nodes are down.

      Please suggest and request to help us to understand why we see this difference in UPTIMES..
