MySQL NDB Cluster 7.3.5를 설치했고 클러스터가 정상적으로 작동하고있었습니다.MEMORY 엔진과 함께 저장된 테이블이 클러스터 장애로부터 복구 할 수 있습니까?
NodeA에 : 4 개 노드
가클러스터 SQLNode1, DataNode1
노드 B : SQLNode2, DataNode2는
NodeC에 : MGMT 노드 1
NodeD : MGMT 노드 2
은을 테스트하려면 서버 재부팅 시나리오 VMWare ESXi를 재부팅하고 모든 VM을 재시작했습니다.
그러나 데이터 노드는 계속해서 시작되지 않습니다.
각각 서버에 대한 로그를 추가 :
/home/mysql/mysqlcluster_data/1/ndb_1_out.log (데이터 노드 1)
error: [ code: 708 line: 38848236 node: 1 count: 1 status: 32687 key: 445914048 name: 'hhmefep/def/fgvmev0000000000-elog-1398414831' ]

노드가이 테이블을 복구하는 데 실패 것으로 보인다 : hhmefep.fgvmev0000000000-ELOG-1,398,414,831
/home/mysql/mysqlcluster_data/2/ndb_2_out.log (데이터 노드 2)

데이터 노드 2는 데이터 노드 1과 동기화하려고하지만 관리 노드에 의해 강제로 종료되었습니다 보인다.
(MGMT 노드)은 매우 실망 때문에
