Description

The enforcement of qtree export rules is different between Data ONTAP running 7-Mode and clustered Data ONTAP when an NFS client has access to the qtree, while its parent volume does not allow access to the same NFS client. A quick overview of the NFS access behavior in Data ONTAP 7-Mode and clustered Data ONTAP is given below:
 
Data ONTAP 7-Mode behavior:

  • 7-Mode supports export paths such as:
    /vol/vol_name/qtree_name/directory_below_qtree_level
  • 7-Mode supports export paths such as:
    /vol/vol_name/directory_at_qtree_level
  • 7-Mode enforces export rules at the qtree level seperately from export rules at the volume level.
  • If a host mounts the volume path, then the export rules on the volume are enforced on the client.
  • If a host mounts the qtree path, then the export rules on the qtree are enforced on the client.

Clustered Data ONTAP behavior (8.2.1+):
In clustered Data ONTAP, NFS clients that have access to the qtree also require at least read-only access at the parent volume level.
