What a qtree is

A qtree is a logically defined file system that can exist as a special subdirectory of the root directory within a FlexVol volume. You can create up to 4995 qtrees per volume. There is no maximum limit for the storage system as a whole. You can create qtrees for managing and partitioning your data within the volume. Qtrees are available only for FlexVol volumes, not for Infinite Volumes.

In general, qtrees are similar to volumes. However, they have the following key differences:

There are no restrictions on how much disk space can be used by the qtree or how many files can exist in the qtree.
