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.

在 NetWorker 服务器和存储节点的 daemon.raw管理此进程:
- Linux:
/nsr/logs/daemon.raw - Windows(默认值):
C:\Program Files\EMC NetWorker\nsr\logs\daemon.raw - NetWorker:如何使用nsr_render_log呈现.raw日志文件
Cause
- 而
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
- 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
- 将以下内容添加到该文件中:
curlConnectTimeout=40000 nwTimeoutSecs=600 echoInterval=15000
- 保存文件。
- 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
- 如果 Windows NetWorker 存储节点也是 NetWorker 服务器,请运行:
