Stupid Question Time: Disk Tests
So...
How do you run SMART tests? Or see the results?
Link below describes what the following do:
- Scub
- Defrag
- Balance
But NOT what Disk Test does.
Neither does:
So I schedule Disk Test last night.
And got the following in the volume log:
| Thu Apr 6 2017 14:59:01 | Volume: Disk test completed for volume data. | |
| Thu Apr 6 2017 4:10:02 | Volume: Disk test started for volume data. |
Which is not what I expected.
So how do you run SMART tests on all the disks?
I found "Thank you StephenB, that was helpful. I checked all SMART stats and found nothing abnormal." via https://community.netgear.com/t5/Using-your-ReadyNAS/ReadyNAS-516-Disk-Test-Results/td-p/974907
But I cannot seem to find how to initiate SMART Disks tests.
Disk log is empty.
Sorry for stoopid question :catlol:

I believe you actually did run the extended SMART test on the drives when you ran the disk test. But the documentation doesn't spell that out (and probably should). The smart history is updated when the stats change, so it doesn't have entries when tests run and pass.
There is also a short SMART check done periodically - that should also be in the manual, and isn't.
Of course, SMART stats are continuously maintained in the drive, so errors that show up in scrub, balance, etc also show up in the smart stats.
You can see the most useful smart stats and the maintenance history if you download the log zip and look in volume.log

Thanks.
I am very surprised that critical information such as SMART test results are not presented in the web portal. After all you bought a NAS and have some RAID configuration, and the critical information is not easily accessible.
Who cares about what interface or RPM your disks have? It never changes and can't be changed. And is potentially already presented in GUI. So why have it in the tool tip?
But SMART results, reallocation of sector, power-on hours are important and nowhere to be seen.
All style over substance in this typical new modern UI that every vendor seems to be developing. Meanwhile you disks are about to fail and they typical user will be none the wiser.
Anyway... Thanks again!

It is there. If you go to the performance tab, and then hover over the disk status icon (e.g., green ball), you can see the parameters under "health data". You do have to scroll down to see it all.
I find that a bit cumbersome to explain (also to use), so I generally go with the "download the logs" method here. If you have ssh enabled, you can of course just use smartctl.
