ReadyNAS 2312 locking up
(I do wonder why my modle, the ReadyNAS 2312, is not listed in the Model listing when making a new post? That in itself is a little disconcerting!)
I have a ReadyNAS 2312 and for the most part it's great. However two days in a row I've found it locked up in the morning. And it's actually happening sometime the night before; I have backups that run at 10pm and two days in a row get error alerts that the volume could not be found, and sure enough, in the morning I could not access it via its web browser interface. The frotn of the unit is blinking away like normal, but I can't access it. A soft reboot (press power, wait, press power again) does nothing, further making me believe it's locked up. A hard reboot (long press on the power button) shuts it down, then I can start it up again and access it fine.
The logs show no errors at all. After this morning's reboot, the last entries in the logs other than today's reboot was yesterday's reboot — background services starting up, and the snapshots running.
Without anything useful in the logs, I'm at a loss how to troubleshoot this. I really dont't think I shoudl have to schedule a reboot every day (I actually scheduled one for every Sunday yesterday, since prior to this, I've only had two do this may be once every few months), so today's sercond lockup in 24 hours has me concerned.
Any ideas, hints, thoughts, or suggestions before I pay for a tech supprot call where they say "have you tried rebooting it, sir?"

I'd start by running a disk test from the volume settings wheel (volume tab in the web ui). That will take a while (depending on how many disks you have). Not finding a volume seems likely to be disk-related.
Ah, the hidden commands you don't know are there ;-)
I've started it, and will report back when it's dond!
There is also a lot more information available in the downloaded log .zip file than in the log in the GUI. So much so, it can be daunting to try and find a clue as to what is going on.
When I was having an apparent lock-up problem, I left an SSH session open on a PC with it running top, and I found that the readynasd process was getting to 100% of CPU use and basically locking out most everything else (but, fortunately, not the SSH session and top). The root cause for that probably isn't germane to your situation, but the same process may help find what yours is.
Update… I ran the disk test, and it did in fact report a drive was failing!
Volume: Disk test failed on disk in channel 10, model ST12000VN0008-2JH101, serial nnnnnnn.
Not a whole lot of info, but I am getting the drive replaced. In the meantime, the crashes are more and more frequent. Yikes. Yes, I should have spare drives on hand, but I don't.
Is there a way to have the ReadyNAS schedule a disk test? The menu option is quite hidden; I don't know what would have happened if I hadn't posted here. I suppose it would have just eventually totally failed, and that point it'd notify me?
I'll update again once I swap the drive in and the NAS rebuilds.

You can download the logs and look at smart_history.log. That will tell you if there were any warning signs from SMART stats that the disk had problems and when.
You can schedule volume maintenance. Go to System > Volumes, click on the Settings wheel next to the volume and go to Volume Schedule and add the Maintenance Schedule. Disk Test is one of the options.
