资源清理活动
使用以下命令清理失败的操作：
pcs resource cleanup <resource> --node <node-name>
[root@prihana ~]# pcs resource cleanup SAPHana_HDB_00 --node prihana Cleaned up SAPHana_HDB_00:0 on prihana Cleaned up SAPHana_HDB_00:1 on prihana Waiting for 1 replies from the CRMd. OK [root@prihana ~]#

手动将资源从一个节点迁移到另一个节点（如前一节所示）将在pcs配置”pcs
config show”。

在使用以下命令执行任何其他集群操作之前，需要清理这些位置约束：
pcs constraint remove constaint-id
