In one of the Sharded replica set, 2 members are listed as primary and not able to connect via mongos. Is this an expected behavior?

Hi @Rajavignesh_Paranira,

That is definitely not expected behaviour.

Please provide some more information:

  • version of MongoDB server

  • output of rs.status() and rs.conf() from each of the members that thinks it is primary with any identifying details (hostnames or IPs) replaced with anonymised equivalents

Thanks,
Stennie

Mongo Version: 4.4
Identified the member that did not sync and removed it from the replica set. Cleaned up the member and added it back.

“xxxw11.yyy.com:20019” & “xxxs10.yyy.com:27017” was showing as primary that caused this issue.
