I just purchased a ReadyNAS NV v2+ yesterday.
After the intial sync and updating to 5.35, I created a couple of users and rebooted the NAS. One of the users I created disappeared from the security menu. I can still connect to it with that user, but I can't administer it.
Looks like this guy is having the same problem: http://www.readynas.com/forum/viewtopic.php?f=23&t=63636
It's not a browser issue. I used Chrome, Firefox and Safari. No dice on any of them.
As such, I figured a reinstall of the OS (good start, not even a day in and I have to boot/nuke) would be the way to go. So I shutdown the NAS, and invoke the boot menu. Normal comes up. I can not change any options. Pressing backup doesn't change anything. I know the backup menu button works, as once the NAS booted up again, attaching a USB drive and pressing the Backup button popped a couple of notifications in my ReadyNAS dashboard.
Faulty unit? Or am I doing something wrong?
