우리는 RHEL 7에서 실행되는 Redhat Pacemaker를 사용하여 2노드 클러스터를 실행하고 있습니다. 지난 목요일(2022년 3월 2일) 커널을 최신 버전으로 업데이트했습니다. 첫 번째 노드는 금요일 오후 3시 49분에(알 수 없는 이유로) 재부팅된 후 다시 조인되었지만 이때 리소스는 Node2에서 실행 중이었습니다.
오늘 CPU 사용률이 높고 top 명령이 표시되는 것을 확인했습니다.
%Cpu(s): 2.9 us, 89.8 sy, 0.2 ni, 7.1 id, 0.0 wa, 0.0 hi, 0.0 si, 0.0 st
어떤 프로세스가 CPU의 89.8%를 차지하고 있는지 모르겠습니다.
