适用场景

  • ONTAP 9.8及以上
  • 已启用FPolicy

问题描述

  • FPolicy似乎无法处理NFS中较长的文件路径。
  • ONTAP应答客户端NFS请求时 "NFS3ERR_JUKEBOX" 出错。
  • ONTAP事件日志可能会引发类似的消息 "Nblade.dBladeNoResponse.NFS: File operation timed outbecause there was no response from the data-serving node.Node UUID:XXXX, file operation protocol:NFS, client IP address: XX.XX.XX.XX, Opcode/Procedure: NFS3_RENAME(14)."
  • 对于路径名较长的卷、可能会观察到较慢/较高的延迟。
  • 无需 连接外部FPolicy服务器、即使在"已断开连接"状态下也会出现问题。
  • 单个路径不需要很长-例如,在NFS_RENAME的某个screen _Req数据包中,如果同一路径名出现多次,则可能导致屏幕_Req数据包较大 (即、在"从/到"路径长度约为3500字节的情况下、使用NFS_RENAME可能会触发此问题)。
