When you specify a path to export to NFS clients or to share with CIFS clients, you should use the complete path name.
Assume a vFiler unit named vfiler1 uses the /vol/vol1 volume for storage. To export the home directory at the root of this volume to the clients of vfiler1, you should use /vol/vol1/home in the /etc/exports file or in the exportfs command.
Assume a vFiler unit named vfiler1 uses the hosting storage system’s /vol/vol1 volume as its primary storage. To share the entire volume, and all other storage owned by the vFiler unit, in a single tree, you should specify / as the share path. To offer the home directory at the root of this volume as the home share, specify /home as the path name for the home share. The vFiler unit mechanism that makes this possible is known as pseudo-root.
