I have a 6 node replica set (all of them data bearing) with 5 voting members. If I lose 3 voting members, I will not have a majority voting members and my replica set will become read-only. In this scenario, if the application has a read concern of "majority", will the reads fail? I have read that this majority read concern introduces a "cache pressure" but will the reads fail?? Or do I need to disable the RC by the below options for basic reads (with majority) to work?
--enableMajorityReadConcern command line option to false.
replication.enableMajorityReadConcern configuration file setting to false.
