Replica Set primary ready connect secondary failed

I have done a reconfigure on the primary host, so now it’s fine and working.

The PRIMARY seems to be initiated

  • rs01:PRIMARY> rs.status()
    {
    “set” : “rs01”,
    “date” : ISODate(“2021-09-16T09:54:05.971Z”),
    “myState” : 1,

    “syncSourceId” : -1,
    “heartbeatIntervalMillis” : NumberLong(2000),

    },

    “name” : “rocketchat1:27017”,
    “health” : 1,
    “state” : 1,
    “stateStr” : “PRIMARY”,
    “uptime” : 5494,
    “optime” : {
    “ts” : Timestamp(1631786038, 1),
    “t” : NumberLong(127)
    },
    “optimeDate” : ISODate(“2021-09-16T09:53:58Z”),
    “syncingTo” : “”,
    “syncSourceHost” : “”,
    “syncSourceId” : -1,
    “infoMessage” : “”,
    “electionTime” : Timestamp(1631780558, 1),
    “electionDate” : ISODate(“2021-09-16T08:22:38Z”),
    “configVersion” : 2,
    “self” : true,
    “lastHeartbeatMessage” : “”
    }
    ],
    “ok” : 1,
    “operationTime” : Timestamp(1631786038, 1),
    “$clusterTime” : {
    “clusterTime” : Timestamp(1631786038, 1),
    “signature” : {
    “hash” : BinData(0,“AAAAAAAAAAAAAAAAAAAAAAAAAAA=”),
    “keyId” : NumberLong(0)
    }
    }
    }

On the rocketchat2 now I want to inititate the secondary replicaset.

rs.initiate( {
… _id : “rs01”,
… members: [
… { _id: 0, host: “rocketchat1:27017” },
… { _id: 1, host: “rocketchat2:27017” }
… ]
… })
{
“ok” : 0,
“errmsg” : “Our config version of 1 is no larger than the version on rocketchat1:27017, which is 2”,
“code” : 103,
“codeName” : “NewReplicaSetConfigurationIncompatible”
}

<something ent wrong and I am not sure what gets wrong.

You either initiate it all at once or incrementally add members.
