Cause
Dell Technologies 已發現雲端資料移動功能中的程式碼瑕疵,這會導致 DDFS 重新開機時發生上述 SEGFAULT 或核心錯誤。 Jira 參考資料是 DDOSCFD-9678
Resolution
為避免 DDFS 在雲端層資料移動期間重新開機,請考慮升級至 DDOS 7.7.1.10 或更新版本、7.7.2.0.10 或更新版本、7.8.0.20 或更新版本
步驟: 1.暫停雲端資料移動程序 # data-movement stop # data-movement status 2.檔案系統重新開機 # filesys restart 3.確定檔案系統已啟用 #filesys status 4.將系統升級到DDOS 7.7.1.10 或更新版本、7.7.2.0.10 或更新版本、7.8.0.20 或更新版本。 5.恢復雲端資料移動程序 # data-movement start
