    Description

      I have a mongo master and replica-set running in docker. I was doing a load test using JMeter using Golang as the server which writes to the database. 

      In the middle of the load test, I pulled the plug (I mean literally). 

      I turn the machine back on, login to the mongo console.

      I did a db.newCollection.count(), it resulted 2007.

      I did db.newCollection.remove({}), it said in the output " WriteResult({ "nRemoved" : 1767 }) "

      Then I did a db.newCollection.count(), it said 240.

      but, but, 

      when I did a db.newCollection.find() it shows nothing.

       

      I am attaching the screenshot below.

       

       

      I have also attached the mongo logs below if that helps!
