自動化中繼資料傳回失敗,並出現以下錯誤:
The active metadata device is not healthy
從用戶端記錄:

客戶對兩個叢集上的中繼磁碟區使用相同名稱:

Cause
UI 代碼使用磁碟區名稱篩選出事件。在這種情況下,cluster-2 中的元卷與cluster-1 metavolume的名稱相同,這使cluster-2混淆了。
由於使用中中繼資料磁碟區在兩個叢集上具有相同的名稱,而且自動備份在兩個叢集上會同時排定 (VPLEX 時間 23:30),因此 cluster-2 會誤以為其
由於使用中中繼資料磁碟區在兩個叢集上具有相同的名稱,而且自動備份在兩個叢集上會同時排定 (VPLEX 時間 23:30),因此 cluster-2 會誤以為其
amf meta restore 在收到 cluster-1 時完成 amf/203 event,而實際上它是 cluster-1 amf meta restore 就完成了。Resolution
因應措施:
若要避免此問題,請為每個群集上的每個元卷使用唯一名稱。(叢集 1 和叢集 2)
Additional Information
此問題也可能表現為備份元磁碟區消失和/或備份日期遺失。
