NetApp 存储网格

问题解答

停用可能需要数天、数周甚至数月才能完成。如果需要,您可以在特定阶段暂停停用操作步骤。

要查看停用任务的进度、请转至: 

  • 网格拓扑 > 主管理节点 > CMN > 网格任务,然后查看 " 取消配置 " 完成情况。停用即将完成时、进度可能会在+/- 95%左右达到一定水平。这是正常行为。
  • 网格拓扑 > 存储节点 > 报告 > 已用存储容量 并验证已用存储容量是否正在减少。

  • StorageGRID Grid Manager -> SUPPORT -> Metrics ->-> Node (Internal Use) ->->->->的图表Time Spent on IO per Device中可以看出、名为sdrsdaj 的两个磁盘设备始终保持100%的磁盘利用率。
    这是因为此图表基于 iostatStorageGRID基础操作系统的Linux命令、而这两个磁盘设备用于元数据存储(StorageGRID-obj-00)、在停用期间迁移数据时、元数据查找会一直处于繁忙状态。Screenshot 2023-02-13 121738.png
