Symptoms
NetWorker 備份設定為移至 CloudBoost 裝置。執行寫入作業的 NetWorker 儲存節點發生CONNECTION_DISCONNECTED錯誤:
錯誤出現在 save 在儲存節點上的進程,但是儲存節點 nsrmmd 精靈會報告以下內容:
MM/DD/YYYY HH:mm:SS nsrmmd SYSTEM critical Unable to write to a file: CONNECTION_DISCONNECTED MM/DD/YYYY HH:mm:SS nsrmmd SYSTEM error Cannot write to base/NW_DEVICE_NAME/##/##/LONG_SSID - errno No error. MM/DD/YYYY HH:mm:SS nsrmmd SYSTEM critical Unable to write buffer to disk for ssid=SSID: Failed opening file / directory base/NW_DEVICE_NAME/##/##/LONG_SSID: Magfs SDK returned: CONNECTION_DISCONNECTED.

在 NetWorker 伺服器和儲存節點中也發現類似的錯誤 daemon.raw:
- Linux:
/nsr/logs/daemon.raw - Windows (預設):
C:\Program Files\EMC NetWorker\nsr\logs\daemon.raw - NetWorker:如何使用nsr_render_log呈現.raw紀錄檔
Cause
- 可使用
nsrmmd儲存節點上的守護程式達到寫入操作的內部逾時。 - 此錯誤是因為 CloudBoost 裝置在觀察到問題時具有大量要求,此增加的負載會導致
nsrmmd連線逾時。
Resolution
- 在用於 CloudBoost 裝置的 NetWorker 儲存節點上,建立名為
nsrcbconfig(無擴展名)以下路徑:
- Linux:
/nsr/debug - Windows (預設):
C:\Program Files\EMC NetWorker\nsr\debug
- 將以下內容新增到檔案中:
curlConnectTimeout=40000 nwTimeoutSecs=600 echoInterval=15000
- 儲存檔案。
- 在 NetWorker 儲存節點上重新啟動 NetWorker 服務:
- Linux:
systemctl restart networker - Windows (PowerShell):
net stop nsrexecd /y ; net start nsrexecd- 如果 Windows NetWorker 儲存節點也是 NetWorker 伺服器,請執行:
net start nsrd - 如果 Windows NetWorker 儲存節點也是 NetWorker Management Console (NMC) 伺服器,請執行:
net start gstd
- 如果 Windows NetWorker 儲存節點也是 NetWorker 伺服器,請執行:
