NetApp StorageGRID

问题描述

  • StorageGRID 存储节点的退役过程在特定阶段经历缓慢或没有进展
    • 登录到网格管理器。
    • 导航到维护 > 停用
    • 对于早于 11.4 的 StorageGRID 版本,停用阶段为"评估 ILM"。
    • 对于高于 11.4 的 StorageGRID 版本,停用阶段为"停用复制数据"。

  • 退役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 Stage 和 "% Complete" 值的 Storage Node Decommissioning 任务。

  • 停用节点正在等待截断相同的对象数据文件: 
    • 通过 SSH 会话登录退役节点
    • 切换到 root 用户:su -
    • 启用调试日志:(echo "moduledebuglevel DCOM 1";sleep 1) | telnet 0 1402
    • 监控退役日志: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:(echo "moduledebuglevel DCOM -1";sleep 1) | telnet 0 1402
    • 确认退役节点重复尝试截断同一对象文件后,等待至少两个扫描周期,然后重复上述步骤来检查退役调试日志。扫描周期可从网格管理器中的仪表板查看。
    • 如果在多个扫描周期之后,节点仍在等待截断相同的对象文件,则此 KB 适用。
