MongoDB University M103: Basic Cluster Administration
#1

While adding shard node to the mongos below error thrown

image

#2

The lab asks

Add shard1 as the first shard in the cluster.

and specifies

shard1 is running on shard1/localhost:27001,localhost:27002,localhost:27003

but you do

sh.addShard( "m103-repl/192.168.56.101:27012" )

So it means, you specified

  1. the wrong replica set name m103-repl
  2. the wrong IP address 192.168.56.101
  3. and the wrong port number 27012

Actually my replicaset is at IP 192.168.56.101:27011,27012,27013, I have changed the configuration as mentioned in the lecture. video URL - https://university.mongodb.com/mercury/M103/2020_March_31/chapter/Chapter_3_Sharding/lesson/5aa31ec196f30f818591a5a0/lecture

Can you please guide me to resolve my issue

You will not be able to verify that lab with this configuration.

But for your current configuration you still have:

because yours is called m103-example.

You really should stick to the lab and use the IDE.

#5

Actually I have completed this chapter in IDE but I am trying this to do it locally in PC for learning purpose and not able to do that

Here is the mongos log file data captured while running the command sh.addShard(“m103-repl/192.168.56.101:27012”)

Kindly guide me to add shard

#6

I think you are using wrong replicaset name while adding addShard
m103-repl vs m103-example
That is what steevej-1495 mentioned in his reply
