    Description

      Target failover causes all clients get IR notify at the same time and all ask MGS for IR config update at the same time also. Right now NID table access is serialized on MGS by single mutex for both write/read access. With many clients that will cause significant delays in getting new failover peer address and reconnect time after all.
