I am running sh.status() command on my mongos instance of sharded Mongo cluster and I am getting below exception.

I am running Mongo 3.2 on ubuntu 16.04 platform. It is working fine on MongoDB version 3.0 on ubuntu 14.04 platform. I have reinstalled everything and tried this on new machines too, everything is working fine except sh.status() command.

Thanks.

It was becuase notablescan property enabled in my mongo config servers. After disable notablescan, command is working fine. you can check status of notablescan by running this command.

db.adminCommand( getParameter: 1, notablescan: 1 )

Output would be like below if notablescan is enabled.

 "notablescan": true,
 "ok": 1
