Replica configuration - MongoDB

Question

On mongo 3.2.17 I have the following output when running rs.initiate(). I need "ok" equal to 1. I don't know how to modified the configuration. Any suggestion?

{
    "info2" : "no configuration specified. Using a default configuration for 
the set",
    "me" : "vpsxxxxxx:27017",
    "info" : "try querying local.system.replset to see current 
configuration",
    "ok" : 0,
    "errmsg" : "already initialized",
    "code" : 23
}

Answer 1

You are getting this error because you have already initialized replication on your machine. This would work on a fresh instance. In your case try using reconfig instead of initiate

rs.reconfig(config, {force: true})

You can use force option when reconfiguring replica set. Make sure you have at least 3 nodes: 2 full nodes and 1 arbiter (minimum supported configuration) or 3 full nodes (minimum recommended configuration) so that primary node can be elected.
