适用场景

  • ONTAP 9
  • FlexCache
  • 远程访问层( RAL )

问题解答

  • 在 ONTAP 启用 FlexCache 后,命令statistics top file show可能会显示大量 deleted inode。 
  • RAL 是 NetApp WAFL® 系统中的一项功能,可使 FlexCache 在索引节点上由原始节点授予缓存可撤销的读 / 写缓存或只读缓存。此功能可启用 FlexCache 功能。
  • RAL 是 FlexCache 用于将内容从集群内部或外部的任何卷加载和操作到初始卷的功能。RAL 是一个流量数据协调程序,用于在 FlexCache 与源服务器之间同步请求,数据,委派,锁定请求以及任何其他信息。
  • 因此deleted inode ,不是触发的用户级别,而是 FlexCache 功能。

Cluster1::*> statistics top file show -interval 30 -iterations 1 -max 10 -node nodename
