Symptoms

例如,請參閱以下情況:

-------------   --------------   ------   -----------   ---------------   ----------- 

# ddboost storage-unit delete My-Storage-Unit

The 'ddboost storage-unit delete' command will delete all files in the storage-unit.
        Are you sure? (yes|no) [no]: y

ok, proceeding.

**** MTree "My-Storage-Unit" has retention-lock configuration, can be deleted only if it is empty.

Cause

儘管儲存單元報告為0.0 GB,但它確實包含檔或目錄。內容的總和大小小於十分之一 GB。

若要檢查,請在任何自動支援報告中搜尋目錄管理員統計資料「DM STATS」,並檢閱有問題的 MTree 項目:

DM STATS for Active context -- uptime=8611998s, mtree_count=76, inode_count=398777, snapshot_count=93, DM_size=779878400

儲存單元的回報為 10,而對於空的 MTree #Inode,則應改為 4。因此,仍有一些文件必須首先從存儲單元中刪除。

Resolution

請使用任何可用的通訊協定 (例如 BOOST 或 NFS) 存取儲存裝置,然後手動刪除檔案。

儲存單元中沒有檔案保留後,啟用 RL 治理的儲存裝置刪除應會如預期進行。已啟用 RL 法規遵循 在 7.3 之前的 DDOS 版本中為空白,也無法刪除 MTree。檢查 Data Domain:保留鎖定常見問題 以取得詳細資訊。
