适用于

  • NetApp StorageGRID
  • NetApp StorageGRID 设备
  • NetApp StorageGRID 基于 VMware 的节点
  • NetApp StorageGRID 基于裸机的节点

说明

本文有助于确定 StorageGRID 节点关闭的原因。多种原因可能导致 StorageGRID 节点处于断开连接状态,例如:

  • 维护操作
  • 网络连接问题(GRID 网络)
    • GRID 网络用于节点间通信。
    • 这是节点到主管理节点之间的连接。 
  • 硬件问题
  • 文件系统损坏
  • 资源问题(如 CPU、内存或磁盘)。资源问题的一个常见症状是系统 shell/cli/ssh 内的响应迟缓/缓慢。
  • 停用

StorageGRID 可能会报告以下错误:

  • StorageGRID 节点出现在网格管理器中的蓝色图标 StorageGRID node(s) (断开连接 – 未知)旁边
  • StorageGRID 报告 Unable to communicate with Node 警报
  • Unexpected node reboot 如果节点自行重新联机
  • StorageGRID 报告 NDDOWN 旧警报
  • 如果启用了 AutoSupport,它将打开一个 NDDOWN AutoSupport 事件:
    • CSTARS:StorageGRID Notification from <serial number> (NODE_DOWN-CRITICAL) ERROR
