适用于

ONTAP 9.14.1 及更高版本

问题解答

bootarg nblade.nfs.eventBasedExport_enabled 控制 ONTAP 如何处理 NFS 导出规则的更新，特别是刷新其导出策略的内部缓存的方法。

如果为 True（基于事件的倒带）：

  • 系统会立即对导出策略或 qtree 规则的更改做出反应。
  • 它专为频繁和动态更改的环境而设计，使更新在这些条件下更快、更高效。
  • 在 ONTAP 9.14.1 中引入并在 9.16.1 中扩展以支持 qtree。

如果为假（基于计时器的倒带）：

  • 系统会按时间间隔刷新导出规则
  • 这在导出规则不经常更改的环境中可以更加稳定。
  • 禁用它可以帮助避免 NFS 超时或延迟。
