Those screenshots you posted are not from the Greyhole UI. The last one is, but the first two were not so I did not know if you were using the app.I obviously have the Greyhole UI since I just posted screenshots from it. How do I do what you're telling me to do?
As for assisting, I will be happy to help. When you have a more complicated set up as you do, it's a must to know a little Linux command line. You will need it to often do more advanced things.
The basic setup of an HDA is simple. When you start adding disk drives, Greyhole, and other pieces it becomes more complicated and requires some degree of understanding of how to do things via command line.This seems to be really unstable and I can't understand why this has been all over websites as something a newbie can use.
I will take another look at your settings and get back with you on what to do next. You should understand that setting up and maintaining any server will not be simple. There is always complications when you do advanced things such as add drives or use Greyhole.
