执行聚合修复后报告SyncMirror丛失败
适用场景
- ONTAP 9
- MetroCluster FC
- 采用NetApp E系列后端的FlexArray
问题描述
- 在强制进行逐项切换后、将在接受站点上运行聚合修复、此时将显示成功：
mcc.drsom.fsmStateTrans:debug]: params: {'from_state': 'heal_aggrs_in_progress', 'event': 'success'}mcc.drsom.fsmStateEntry:debug]: params: {'state': 'heal_aggrs_complete'}- 接下来会出现SyncMirror丛故障：
