I followed the instructions listed and here is what I found. I have node 1, 2 and 3 up.
I connected to the 3 nodes and verified that node1 is the primary.
I connect to node2, shut it down and restart the node with the new configuration file. All good here.
I connect to node3, shut it down and restart the node with the new configuration file. All good here.
Now I connect to node 1 (port 27011). I see that this node is no longer the primary. It is listed as a secondary. So I am unable to do the rs.stepDown(). But in the video at 5.04, when connecting to the primary node, it shows as PRIMARY but that is not the case for me.
What am I doing wrong?
