Today, we're going to find out how to test each hard drive in a QNAP TS-451, and
also learn how to schedule these tests on a regular basis in order to protect
your QNAP from drive failures. This tutorial applies to any QNAP unit that
runs on the QTS operating system. In a NAS, or a Network Attached Storage unit,
the integrity of each drive is of paramount importance, because after all,
the primary function of NAS is to store data. One level of protection is RAID, or
Redundant Array of Independent Disks. You can use RAID 1, 5, 6, or 10 by storing your
data on redundant drives, but regardless of what level of RAID you're using, you
need to know if you have a bad hard drive as soon as possible.
The sooner you're aware of a failing drive, the sooner you can replace it. Of
course you shouldn't rely on redundant drives only. RAID by itself is not enough
to safeguard your data; you should have a good backup plan in place. After all, more
than one drive could fail at one time. Even worse, the QNAP hardware itself
could fail. I'll cover the topic of backing up to an external drive in a future video.
QNAP provides diagnostic tools to perform SMART
tests, or Self Monitoring Analysis Reporting
Technology, that's embedded in all of your hard drives, but it doesn't do it
automatically. You need to run them manually, or schedule the test to run at
regular intervals. Here, I've logged into QTS. To schedule the tests, you'll need to
start the Storage and Snapshots application. Tab over to the Disks section,
where you'll see the health information for each of your installed drives. You'll
want to click on Disk Health, and navigate to the Test section.
QNAP provides a rapid test, which lasts about a minute, and a complete test, which
can run for hours.
The drop-down allows you to choose which disk you want to test, but these are one-time operations.
If you ever want to test your disks again, you'd need to come back to this
screen and manually re-perform the tests. However, if you want to automate these
tests, you'll need to tab to Settings,
and enable the rapid and/or the complete
tests. You can perform these daily, weekly, or monthly. Some people schedule the
rapid tests daily and the complete tests weekly, while others do the rapid tests
weekly and the complete tests monthly. I fall in the latter group, so I'll enable
the rapid tests weekly on a Monday at 9:00 am,
and I'll enable the complete test monthly
on the first of the month at noon. You'll probably want to schedule the tests at a
time when you aren't performing a backup, or when you won't be using the QNAP
too heavily, especially for the long complete test. If you hit the Apply
button, you're scheduling the test to the individual disk in the drop-down list.
The Apply to All buttons force all four disks to follow this schedule.
So when the time comes to trigger the tests, QNAP will tell you whether they've
been successful or not. If one of the SMART tests fails, you will be notified
in the Event Notifications. When that time comes, you'll want to replace that
disk as soon as possible.
I hope you enjoyed - Thanks for watching!
