You could try unmounting it with umount, and then restarting - not sure if the umount will work, but it is safe to try.
The other option would be to boot into tech support mode.
But something is really wrong here - you shouldn't be seeing these problems over and over if you have healthy disks. I don't know what is going on, but I am wondering if you should pursue a warranty replacement.
I believe you should be able to unmount the main volume as long as you have no apps that are running that reside on it.
One thing to verify if you just delete and re-create the volume is that the home and apps shares are created properly. I ran some experiments, and had them not be a couple times. Netgear could not duplicate the problem, so there is no fix. I happen to know how to create them myself, and so I did.
