适用场景

NetApp StorageGRID

问题描述

  • 在特定阶段、StorageGRID存储节点的停用过程速度较慢或无进展
    • 登录到网格管理器。
    • 导航至 Maintenance (维护) > Decommmission(取消)。
    • 对于11.4之前的StorageGRID版本、停用阶段是"评估ILM"。
    • 对于11.4以上的StorageGRID版本、停用阶段为"停用复制的数据"。

  • 停用任务的完成百分比进展缓慢或根本没有进展
    • 在网格管理器上,导航 到 “支持   ”>  “网格拓扑”>“主管理节点”>“CMN”>“网格任务”。
    • 检查 存储节点停用 任务的阶段和"完成百分比"值。

  • 停用节点 正在等待相同对象数据文件的终止: 
    • 通过SSH 会话登录到停用节点
    • 切换到root用户:su -
    • 启用调试日志记录:(echo "moduledebuglevel DCOM 1";sleep 1) | telnet 0 1402
    • 监控取消命令日志:tail -f /var/local/log/bycast.log | grep DCOM
    • 验证日志是否重复显示类似于以下内容的消息:
    • Feb 24 14:48:59 <nodename> ADE: |12983731 0734583769 DCOM CSRT 2023-02-24T14:48:59.113673| INFO     0405 e3e6699e31d46b7e DCOM: Waiting for data file /var/local/rangedb/0/p/02/1F/00qLyqjT>z-sgPRdr4$h to be truncated
    • 禁用调试日志记录:(echo "moduledebuglevel DCOM -1";sleep 1) | telnet 0 1402
    • 确认停用节点 重复尝试缩减同一对象文件后、请等待至少两个扫描期间、然后重复上述步骤以检查停用调试日志。可以从  网格 管理器中的Dashboar查看扫描周期。
    • 如果经过多个扫描时间段后、节点 仍在等待截断同一对象文件、则此知识库文章适用。
