Symptoms

  • 前往 Data Domain 的備份失敗,並出現下列錯誤:
202836:save: Unable to write to a file due to stale handle.
The error message is: [5057] [10456] [4084] Tue Apr 21 23:56:36 2026

209610:save: DD boost operation aborted on entry because Quit flag is set
  • 某些存儲集可能會成功完成,而其他存儲集則失敗並出現上述錯誤。

Cause

當 NetWorker 嘗試寫入已關閉的檔案控制代碼時,就會發生此問題。
在這些情況下,檔案控制碼會在 3 小時無活動 (預設逾時) 後被 Data Domain 標示為放棄。
針對忙碌的用戶端或大型備份,可能需要額外的時間來整合資料,導致備份超過預設放棄逾時,並導致檔案控制碼過時。

Resolution

若要解決此問題,請增加OST_ABANDON_TIMEOUT值,以留出額外的時間進行備份整合。

通過增加超時值,可以防止檔句柄過早關閉,從而避免檔系統同步期間出現過時的檔句柄錯誤。

建議的逾時:8 小時(28,800 秒)
在極少數情況下,可能會增加到 12 小時(43,200 秒)

警告:此變更需要 SE 模式存取和 Data Domain 檔案系統重新啟動,這需要排定的停機時間。若要存取 SE 模式,必須透過支援票證聯絡 Data Domain 支援。
