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.
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.

Meaning that each of these runs once every four months? Seems like a long interval, no? Which is of course a lot more than I have been running it, though ;-)

aha! So this is interesting…
that one with errors is in fact the problem drive. You'd think the system would notify me; it sends me emails every time it farts, but not when it has a failing drive? Grrr

Super, thank you.

It can be subjective when to replace a disk, though a sudden increase from 0 to 48 reallocated sectors is something worth paying attention to and any current pending sectors suggests a disk is failing.
I agree that it would be nice if there was the option to configure alerts for any change in key SMART stats.
