适用场景

  • ONTAP 9
  • 外部聚合
    • RAID.sAm.tree.foreign
  • 陈旧的聚合
  • 孤立聚合

问题描述

如果将磁盘引入某个节点,而这些磁盘来自另一个系统,并且没有正确地 取消所有置零,则这些磁盘将报告为其所属节点所有,并且当前节点无法访问这些磁盘。

  • 当RAID树对象包含与本地系统不同的所有权标识符时、会发生这种情况。
    • 在这种情况下、聚合将 "foreign"被声明并标记为脱机。
    • 卷可能不会显示在集群级别、而是显示在节点级别。
如何验证
  1. 运行以下命令以确定聚合标记为外部的节点。
    相关聚合的标签为 foreign.
    ::> node run -node * sysconfig -r

Aggregate aggr0 (offline, raid_dp, foreign, degraded) (block checksums)
  Plex /aggr0/plex0 (online, normal, active, pool0)
    RAID group /aggr0/plex0/rg0 (double degraded, block checksums)
