Symptoms

NetWorker 备份配置为转到 CloudBoost 设备。执行写入作的 NetWorker 存储节点观察到CONNECTION_DISCONNECTED错误:
该错误出现在 save 在存储节点处进行进程,但为存储节点 nsrmmd 守护程序报告以下内容:

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.
MM/DD/YYYY HH:mm:SS nsrmmd NSR warning Unable to close or sync file for ssid=SSID: Failed to get fd for ssid=SSID to sync/close file
MM/DD/YYYY HH:mm:SS nsrmmd SYSTEM critical Unable to remove SSID file 'base/NW_DEVICE_NAME/##/##/LONG_SSID' on device 'rd=storagenode:base/NW_DEVICE_NAME': Unable to stat save set file 'base/NW_DEVICE_NAME/##/##/LONG_SSID': Unable to retrieve the file statistics: CONNECTION_DISCONNECTED
MM/DD/YYYY HH:mm:SS nsrmmd NSR error MM/DD/YY HH:mm:SS nsrmmd #5: save set \\NAS_FILER\CIFS_SHARE$\~snapshot\backup.0 for client nw_client_NAS was aborted and removed from volume VOLUME_NAME
MM/DD/YYYY HH:mm:SS nsrsnmd SYSTEM notice nw_cbcl_disconnect: Mount handle is NULL.

在 NetWorker 服务器和存储节点的 daemon.raw管理此进程:

Cause

  • nsrmmd 存储节点上的守护程序达到写入作的内部超时。
  • 此错误是因为 CloudBoost 设备在发现问题时有大量请求,此增加的负载导致 nsrmmd 到超时的连接。

Resolution

  1. 在用于 CloudBoost 设备的 NetWorker 存储节点上,创建名为 nsrcbconfig (无扩展名)在以下路径中:
  • Linux: /nsr/debug
  • Windows(默认): C:\Program Files\EMC NetWorker\nsr\debug
  1. 将以下内容添加到该文件中:
    curlConnectTimeout=40000
    nwTimeoutSecs=600
    echoInterval=15000
  2. 保存文件。
  3. 在 NetWorker 存储节点上重新启动 NetWorker 服务:
  • Linux: systemctl restart networker
  • Windows (PowerShell): net stop nsrexecd /y ; net start nsrexecd
    • 如果 Windows NetWorker 存储节点也是 NetWorker 服务器,请运行: net start nsrd
    • 如果 Windows NetWorker 存储节点也是 NetWorker Management Console (NMC) 服务器,请运行: net start gstd
