集群管理

要手动将群集资源从一个节点迁移到另一个节点，请运行以下命令：

prihana:~ # crm resource move msl_SAPHana_HDB_HDB00 force
INFO: Move constraint created for msl_SAPHana_HDB_HDB00
INFO: Use `crm resource clear msl_SAPHana_HDB_HDB00` to remove this constraint

使用命令 “crm_mon –r” 检查迁移状态。

prihana:~ # crm_mon -r

资源迁移完成后，您可以检查群集的状态。清理失败的操作，如下一节所示。
