状态信息

适用场景

ONTAP 9

问题描述

  • 精简配置卷中的LUN由于卷空间不足而脱机、尽管聚合有大量可用空间。
  • LUN在ONTAP 中显示利用率为100%、但客户端占用的空间较低、并且LUN因空间不足而脱机。
  • 精简配置卷中的LUN由于卷空间不足而脱机。

卷配置示例:

  • 预留百分比已禁用(0%)
  • LUN空间预留为 off
  • 卷保证为 none
  • 卷自动增长为 off
  • Snapshot自动删除为 off
  • 由于卷空间不足、厚配置卷中的精简配置LUN脱机。

卷配置示例

  • 预留百分比已启用(100%)
  • LUN空间预留为 off
  • 卷保证为 volume
  • 卷自动增长为 off
  • Snapshot自动删除为 off
  • 聚合上的空间不足
