适用于

  • ONTAP 9
  • -atime-update(访问时间更新)
  • -is-atime-scrub-enabled

问题解答

  • -atime-update (访问时间更新)是一个卷级字段,用于管理使用 READ、READLINK 和 READDIR 读取的文件和目录的访问时间更新。
  • 由于可能的性能影响,建议在以下情况下禁用 -atime-update:
    • 在早于 9.11.1 的 ONTAP 版本中使用 FlexCache 时
    • 使用 SQL 工作负载时
    • 使用 VMware Virtualization for ONTAP 时

注意:使用 FabricPool 时,不需要启用 -atime-update,因为 FabricPool 在块级别工作。
