适用于

  • Data ONTAP 7-模式
  • 集群模式 Data ONTAP 8
  • ONTAP 9

说明

当 CIFS/NFSv4 客户机首次访问目录时,可能会触发 Unicode 转换。 如果存储环境中已包含具有大量子目录和文件的现有 NFSv3 目录、则自动首次访问转换可能会对存储系统的性能产生影响。

  • 此转换需要大量资源、可能导致系统暂时无响应、包括服务丢失。
  • 转换时可能遇到的症状:
    • 心跳丢失
    • 未同步的日志
    • SSH 访问权限
    • 数据访问
  • 表示转换导致性能下降的 EMS 消息:

Tue Jan 17 14:16:33 CST [netapp_fake: wafl_hipri: wafl.dir.convert:warning]: WAFL converting directoryconversion in progress.

  • CIFS/NFSv4 客户端预期使用大目录是避免处理延迟的关键所在,此问题可能会触发此延迟。
