5.2. 노드 충돌로 인한 장애 조치 ASCS
충돌하기 전에 ERS가 s4node2에서 실행되는 동안 ASCS는 s4node1에서 실행됩니다.

[root@s4node2 ~]# crm_mon -Arf
다음 명령을 실행하여 s4node1을 충돌합니다. 명령 후 s4node1에 대한 연결이 끊어집니다.
[root@s4node1 ~]# echo c > /proc/sysrq-trigger
s4node2에서 장애 조치 프로세스를 모니터링합니다. 장애 조치 후 s4node2에서 ASCS 및 ERS를 사용하여 클러스터가 해당 상태에 있어야 합니다.
