Symptoms

NetWorker VMware Protection (NVP) 集成已通过 vProxy 设备进行配置。虚拟机 （VM） 备份失败，NetWorker 工作流日志显示： 
MM/DD/YYYY HH:MM:SS [VM_NAME]: Unable to start backup on vProxy '[VPROXY_NAME]': Received an HTTP code: 500, libCURL message: "", vProxy message: "Error received from vProxy ="-500: Panic occurred: runtime error: invalid memory address or nil pointer dereference".

Cause

vProxy 一体机上的 /data01文件系统已满。存储由备份会话日志使用，这些日志位于“/opt/emc/vproxy/runtime/”（位于 /data01）目录中，默认保留期为一个月。vProxy 无法写入会话日志来启动备份。

Resolution

可以重新部署 vProxy 一体机以清除现有日志。vProxy 不包含执行已备份数据恢复所需的任何信息。 

Additional Information

可以通过从以下位置删除日志来回收 vProxy 的 /data01 装载点上的空间：/data01/runtime/logs/recycle/

下面是一个创建 cron 作业的示例过程，该作业将删除 14 天前的日志：

  • 以管理员身份通过 SSH 登录 vProxy，然后切换到 root： sudo su - root
  • 使用以下命令为 root 用户创建 crontab 作业： crontab -e
  • 在文本编辑器中，插入以下行以删除每天早上 6 点超过 14 天的会话日志：
* 6 * * * find /opt/emc/vproxy/runtime/logs/recycle/vbackupd -type f -mtime +14 -delete
  • 使用以下命令查看新 root 用户 cron 作业的内容： crontab -l
  • 可以修改保留日志的天数，以防止文件系统达到 100%。
提醒：这些更改不会在 vProxy 升级期间转移。
