Using Virtual Volumes
System Administration Manual

Allow exports to
overlap
As overlapping exports can potentially expose security loopholes, the
condition can be tested for and, if found, the export creation can be
denied. To prevent this check and allow overlapping NFS exports to be
created, check the box labeled 'Allow exports to overlap'.
Path
A directory in the file system that will be the 'root' of the Virtual
Volume. Example: /company/sales. All sub-directories of this path will
be a part of this Virtual Volume. Once created, the path may not be
changed.
Virtual Volumes cannot be created at the root of the file system (“/”).
They must be applied to the directories in the file system.
Virtual Volumes can only be created and assigned to empty directories.
To create a Virtual Volume on a directory that contains data, first
move the data out of the directory Once empty, the Virtual Volume can
be created and assigned to that directory. Then, the data can be
moved back in.
