Hi, i follow your steps in video to do a replication in 2 nodes: one primary and one secondary: it's running but when i added a new node secondary, i do rs.status() in primary node, it 's displayed a message error: "stateStr" : "(not reachable/healthy)", for the second node. DO you have the solution please?

[@shreepowar867]

[@hemanthv6514]

Sir , I did not get stateStr as Secondary after adding it. rs.status() show as "stateStr" : "STARTUP", and am not able to replicate the stuff. could you please help me

[@hasnaelahkim6872]

same problem.

[@kevinchristopher1709]

Issue solved ?

[@alibhutta7583]

How to do this with Ubuntu servers ? and also inform about key file that how we can copy and generate on each server ? It'll be great if you make complete video on it. Thank you

[@r2schools]

It's done on Ubuntu servers only

[@alibhutta7583]

@@r2schools ​ r2schools it is detailed video but some information is still missing e.g IP are whether public or private ? there is no use of : in conf file so information about that and what about key file ? I'll appreciate if you make detail tutorial about it or Make tutorial on this articale : sysadmins.co.za/setup-a-3-node-mongodb-replica-set-on-ubuntu/
