If internally mounted FlexVol volumes form a namespace and you have a mirror relationship, CIFS clients on a destination volume that attempt to view mirrored volumes not at the highest level of the namespace are denied access.
This occurs when you create a namespace using more than one volume, in which one volume is the source volume of a mirror relationship and the other volumes are members of the namespace. For example, assume that you have two volumes: vol x, which has a junction path /x, and vol y, which has a junction path /x/y. When a SnapMirror transfer occurs, a directory under vol x is created for vol y on the destination volume. From an NFS client, you can see that the directory is empty, but from a CIFS client, you get the following message:
access is denied.
