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...

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.
Ah that's helpful. I didn't know the downloaded logs had more. I'll let this disk test finish, then proceed from there. Thanks!
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.

Scrub also accesses every sector of the data volume, so it also will give an early warning of a disk problem.
I run all four of the maintenance functions on a schedule - running one every month. Balance and defrag generally run quickly; the disk test and scrub take much longer. So I use the sequence
- disk test
- balance
- scrub
- defrag
which runs the two long tasks every other month.
Note that if you've never run a balance, then the first one can take quite a while (days). But mine usually complete in about 10 minutes.
