[Users] How to configure sharedFS ?

Hi, From vdsm code i can see support for storage domain of type SHARED_FS But when trying to configure a new storage domain, i don't see SHARED_FS as a available domtype filed in the dropdown. I want to use shared FS to connect to try and connect to gluster mount point on my node, but unable to as I don't see that option. From http://www.ovirt.org/wiki/Features/PosixFSConnection - I understand that its the same as sharedFS, so what is PosixFSConnection then, is it just a new interface that provides a wrapper for what is sharedFS now ? The status of this says Done, but I don't see the UI part of this, am I missing something. Also pls let me know if usign sharedFS to make the node use gluster mount is correct or not ? thanx, deepak
