PowerScale：在工作期間刪除目標配額會導致 SyncIQ 失敗

SyncIQ 在 STF_PHASE_CT_DIR_DELS 刪除目標配額後的階段。

在 SyncIQ 來源叢集上，SyncIQ 工作可能會失敗，並因配額而無法刪除錯誤：

Error at target cluster on node [target-1]:  Unable to delete /ifs/PSCALE-154122/quota1 (1:005d:13c1::131), Local error : Job failed because the job attempted to delete a directory that a quota has been applied to. You must delete all quotas applied on or under /ifs/t_154122/quota1 before this job can continue.

移除目標配額後，SyncIQ 工作便會失敗，並顯示一般 A work item has been restarted too many times. 錯誤：

SyncIQ policy failed. A work item has been restarted too many times.  This is usually caused by a network failure or a persistent worker crash.

在 SyncIQ 目標叢集上，下列項目 FAILED ASSERTION 已登入 isi_migrate.log 檔案：

isi_migr_sworker: *** FAILED ASSERTION tmp_st.st_ino != entryp->d_fileno @ /b/mnt/src/isilon/bin/isi_migrate/sworker/stf_transfer.c:1253: Tmpdir 1:005f:14ba not expected, and moving to itself

刪除 SyncIQ 目標叢集上的配額後，剩餘的 tmp-working-dir 保留在要刪除的目錄中。

請聯絡 Dell PowerScale 支援，以取得因應措施的協助。請提及此知識文章。

將 SyncIQ 原則修改為 delete -quotas=yes。

isi sync policies modify <policy_name> --delete-quotas=yes

如何在即時叢集上尋找錯誤：

在來源叢集上，檢查原則報告中的錯誤訊息：

 # isi sync reports view <Policy Name> <Report ID>

在目標集群上，在消息日誌中查找以下斷言：

isi_for_array -QX 'grep -h "isi_migr.*FAILED ASSERTION tmp_st.st_ino" /var/log/messages' | sort | tail
