저장 데이터 용 mongodb를 실행 중입니다. MongoDB 클러스터에는 3 개의 샤드가 있고 각 샤드에는 3 개의 서버 복제 세트, 2 개의 몽고 및 3 개의 구성 서버가 있습니다. 각 서버에는 1TB의 저장 공간이 있습니다. 이제 3 개의 파쇄물 중 2 개가 90 % 용량의 데이터를 보유합니다. 새로운 샤드를 추가 할 때, MongoDB는 오래된 샤드에서 새 샤드를 옮기지 않습니다. 몽고스 샤딩 상태를 확인합니다. 그것은 저에게 그것을 보여줍니다. MongoDB baclancer가 실행 중입니다.MongoDB가 샤딩 클러스터의 새 샤드로 이동하지 않습니다.
