An update for the list about the use of mount points provided by NTFS v5.

The above system has been implemented and has been live for about a month and there have been no issues with the use of mount points at all. Indeed, it has been amusing watching SA's trying to locate where all of the drives have been "put"!

The easiest method for locating all of the volumes is to select the 'All Drive Paths' option on the View menu in Disk Administrator. The dialog is also useful for removing drive paths should a filesystem be offline for whatever reason - this allows the mounting of the fixed (or a new) filesystem to mounted at the same place in the directory path.

The use of mount points is also useful in attempting to following the OFA guidelines, e.g. the mounting of a separate filesystem at


to allow greater space to be allocated for the storing of archived redo logs.

Many thanks for all of those who replied to my original request.
