Symptoms
增量備份工作失敗,返回代碼 -1,而完整備份成功。記錄檔會顯示類似以下錯誤:
-
MODIFIED_ASOF_TIME:timeval=1735918213;RENAMED_DIRECTORIES:index_lookup=on;BACKUPTIME:lookup_range=1735918230:1735918230;REQUESTED_LEVEL:level=incr; -l incr -q -W 78 -N /data_ecm1 /data_ecm1' for client exited with return code -1 01/05/2025 01:05:39 AM Job 594500 host: savepoint: /data_ecm1 had ERROR indication(s) at completion 01/05/2025 01:05:39 AM PECMAPP1:/data_ecm1 failed. 01/05/2025 01:05:44 AM Action backup traditional 'backup' with job id 594425 is exiting with status 'failed', exit code 1
原則記錄包括:
-
ddp_fsync() failed, Err: 5029 - A previous operation on this file has failed with error code: 5029 and no further APIs can be processed until the file is closed fsys_fsync(): Sync'ing a file failed [5029] _ddp_fsync() Aborting API processing because ddp_fd[...] has previous error[5029] set
Cause
- 錯誤 5029 表示 ddp_fsync() 及相關的 DDBoost API 呼叫失敗。
- 這是隨附於 NetWorker 19.10 的 DDBoost 二進位版本 7.13.0 的已知問題。
- 當以前對檔的操作失敗時,會出現此問題,從而阻止進一步的 API 調用,直到檔關閉。
參考資料:
ddboost_api ERROR: ddp_fstat() failed, Err: 5029 - A previous operation on this file has failed with error code: 5029 and no further APIs can be processed until the file is closedResolution
- 會在 Jira ID 下追蹤此問題:DDOSCFD-20020
- 此修正程式可在 DDBoost 版本 7.13.1、8.0 和 8.1+ 中取得
- NetWorker 無法獨立升級 DDBoost;將 NetWorker 升級至:
- 19.11 (包括 DDBoost 8.0)
- 19.12 (包括 DDBoost 8.1)
Additional Information
- 完整備份不受影響;只有增量備份會間歇性失敗。
- 除了升級到具有已修復 DDBoost 程式庫的版本外,沒有其他因應措施。
- 監控 Dell 版本資訊,以瞭解其他修補程式或修補程式。
