监控集群的状态
您可以使用以下命令检查集群的状态：
prihana:~ # crm status Stack: corosync Current DC: prihana (version 1.1.18+20180430.b12c320f5-3.24.1-b12c320f5) - partition with quorum Last updated: Thu Nov 12 12:35:56 2020 Last change: Thu Nov 12 12:34:57 2020 by root via crm_attribute on prihana 2 nodes configured 6 resources configured Online: [ prihana sechana ] Full list of resources: res_AWS_STONITH (stonith:external/ec2): Started prihana res_AWS_IP (ocf::suse:aws-vpc-move-ip): Started prihana Clone Set: cln_SAPHanaTopology_HDB_HDB00 [rsc_SAPHanaTopology_HDB_HDB00] Started: [ prihana sechana ] Master/Slave Set: msl_SAPHana_HDB_HDB00 [rsc_SAPHana_HDB_HDB00] Masters: [ prihana ] Slaves: [ sechana ]
