适用场景

ONTAP 9

问题解答

  • 为WAFL预留的"隐藏"10%磁盘空间无法调整、root用户也无法在隐藏空间中创建文件。
  • 如果为文件系统分配的存储数据和元数据的物理容量不超过90%、则文件系统的效率会更高。
    • 主要优势在于、每十个块中就有一个块始终可用、因此、文件管理器能够更高效地找到可用空间、并可以更灵活地放置数据以优化磁盘写入。

追加信息

  • 从ONTAP 9.12.1开始、 对于全闪存FAS (AFF)和FAS500f平台、容量大于30 TB的聚合、WAFL预留会减少到5%。
  • 从ONTAP 9.14.1开始、所有FAS平台上的精简适用场景聚合都相同、从而使聚合中的可用空间增加5%。
  • 确定卷或聚合中的空间使用量
  • ONTAP空间使用量
