A qtree is a logically defined file system that can exist as a special subdirectory of the root directory within a FlexVol volume and are used to manage and partition data within the volume.
You can specify the following options when creating a qtree:
By default, oplocks are enabled for the qtree. If you disable oplocks for the entire storage system, oplocks are not set even if you enable oplocks on a per-qtree basis
The security style can be UNIX, NTFS, or Mixed (UNIX and NTFS). By default, the security style of the qtree is the same as that of the selected volume.
Create a new export policy or select an existing policy. By default, the export policy of the qtree is same as that of the selected volume.
