If I recall there is an option to restore back to factory settings but it does not remove any shares, just users rights on existing shares. So this will not do any good.

Since you did a clone you also got the original drive size. You will need to remove the share(s) completely from the system. In the SnapOS we had to do a format of the storage space to gain all of the space. So I suspect it may be the same if wiping out all of the storage space does not gain it. What should work would be to boot into the recovery console, then use the option for a clean install. This is what we do with multiple drive systems. To do a clean install you will need your copy of the GSU (GOS). Once in recovery console select clean install select the GSU file, set back and watch it work.
