If you have run into this issue please upgrade to 4.1.10: http://www.readynas.com/RAIDiator_4_1_10_Notes
You can then use the Advanced Options tab (go to Shares > Share Listing > Sharename then click on e.g. CIFS and you'll see the tab) to reset the ownership to what you want. You can use the Set ownership and permission for existing... option. Don't forget to click Apply to make your changes
My shares are set up so that they are read/write for owner, read-only for the 'users' group and no access for anyone else.
Since upgrading to the new 4.1.9 sparc firmware (http://www.readynas.com/?p=6480
) the owner/group on the top level share directories keep reverting to nobody/nogroup as soon I change any share settings in FrontView.
Changing the 'Share folder owner' and 'Share folder group' in the 'Advanced Options' tab has no effect, they go back to nobody/nogroup the next time you go in. Even just adding a new share is enough to change the owner/group on the other shares back to nobody/nogroup.
At the moment I have to keep SSH'ing in and chmod/chgrp the directories back to what they should be.
4.1.8 was fine so this looks a problem with 4.1.9?
