Symptoms

NetWorker VMware Protection (NVP) 整合是透過 vProxy 裝置進行設定。虛擬機器 （VM） 備份失敗，而 NetWorker 工作流程記錄顯示：

Cause

vProxy 裝置上的 /data01 檔案系統已滿。備份工作階段記錄會佔用儲存空間，這些記錄位於「/opt/emc/vproxy/runtime/」（位於 /data01） 目錄中，預設保留一個月。vProxy 無法寫入工作階段記錄來啟動備份。

Resolution

可重新部署 vProxy 裝置，以清除現有的記錄。vProxy 不包含執行已備份資料復原所需的任何資訊。 

Additional Information

若要從以下位置刪除記錄，即可回收 vProxy 的 /data01 掛接點上的空間：/data01/runtime/logs/recycle/

以下為建立 cron 工作以刪除已滿 14 天之紀錄的範例程序：

  • 以系統管理員身分透過 SSH 登入 vProxy，然後切換至 root： sudo su - root
  • 使用下列命令為根使用者建立 crontab 工作： crontab -e
  • 在文字編輯器中，插入以下行以刪除每天上午 6 點超過 14 天的工作階段紀錄：
* 6 * * * find /opt/emc/vproxy/runtime/logs/recycle/vbackupd -type f -mtime +14 -delete
  • 使用下列方式檢視新根使用者 cron 工作的內容： crontab -l
  • 您可以修改保留記錄的天數，以防止檔案系統達到 100%。
注意：這些變更不會在 vProxy 升級期間移轉。
