The output i shared is from PRIMARY and SECONDARY. As per your statement, im using arbiter in the RS so it should show for all the SECONDARY. But it shows only for one SEC member.
By point is if the warning is correct, then it should show for all 4 members of a RS. but it shown only for one SEC.
Thanks for your reply. Yes we undetstood mongo 3.6 is EOL by next month. I’m in the process of migrating to the latest one. But we are looking this discepency in the existing deployment with 3.6. So raised this question.
