Hi Thorsten,

the " System Administration File Access Management Guide" says:

How Data ONTAP matches mount requests with exported resources

When Data ONTAP receives a mount request from a client, it compares the path name in the mount request to the path names of the exported resources. If Data ONTAP finds a match, the NFS client can mount the resource.

Data ONTAP uses the longest matching prefix in the path name in determining access restrictions.

Example

Suppose you export both the /vol/vol0/home resource and the /vol/vol0 resource. When a host tries to mount the /vol/vol0/home/user1 directory, Data ONTAP applies the access restrictions specified for the /vol/vol0/home resource to determine whether the host should be granted access. Similarly, when a host tries to mount the /vol/vol0 directory, Data ONTAP applies the access restrictions specified for the /vol/vol0 resource.

If I have an entry like this in my exports file:

/vol/vol1/dir -access=host1:host2

should it be possible to mount the directory /vol/vol1/dir/subdir directly? And if so, what happens if I add the following entry to the exports:

/vol/vol1/dir/subdir -access=host3

Can host1 and host2 now only mount /vol/vol1/dir or can they still mount /vol/vol1/dir/subdir? (ONTAP 6.4.1)

Thanks, Thorsten Lemke
