Removing a node from the replica set

In this recipe, we will be looking at how to remove a member from a replica set. If you have done the previous two recipes in this chapter, this should be a breeze.

Getting ready

For this recipe, we will need a three node replica set. If you don’t have one ready, I suggest referring to the first two recipes of this chapter.

How to do it...

      "uptime" : 57933,
      "optime" : {
          "ts" : Timestamp(1503722389, 1),
          "t" : NumberLong(5)
      },
      "optimeDate" : ISODate("2017-08-26T04:39:49Z"),
      "electionTime" : Timestamp(1503721808, 1),
      "electionDate" : ISODate("2017-08-26T04:30:08Z"),
      "configVersion" : 3,
      "self" : true
   },
   {
      "_id" : 1,
      "name...
