In the services, i have SMART turned on with all the default settings: 30 mins, never, 0, 0, 0

The server has been running for months now, but when I read the results, I get no results?

# smartctl -l selftest /dev/ada0
smartctl 6.3 2014-07-26 r3976 [FreeBSD 9.3-RELEASE-p13 amd64] (local build)

SMART Self-test log structure revision number 1
No self-tests have been logged. [To run self-tests, use: smartctl -t]


The box is ticking like this:

tick... delay 1 sec.... tick-tick... delay 1 sec <repeat forever>

So wanted to know if its a disc about to fail or if its supposed to do that?

It only seems to tick when its not been doing anything for a while, e.g. not streaming plex or whatever.

It looks like you're not running smart tests.

For a short test (a couple of minutes), use: smartctl -t short /dev/ada0

For a long test use: smartctl -t long /dev/ada0

To look at the results, use: smartctl -a /dev/ada0

If you'd like us to look at the results from the last command, post the output here and use the code tags. It will preserve the formatting, which is necessary to read the information.

The SMART entry in Services sets up monitoring of the SMART status, but it doesn't run any SMART tests. For that, go to the SMART Tests section of the Tasks tab.

Duplicate - sorry

EDIT: As i have a post i cant delete, i may as well use it :p

The freenas is set up as 4x 3T Discs, in some configuration that gives me 5.5G usable disc space, i cant see how you can see what the raid method is and i cant remember what i set.

The discs are half full now (used 2.6T)

They are WD Red drives, 7 months old.

The easiest way to see how the disks are configured is to do it from the command line: zpool status

If you want us to intrepret it for you, please use the code tags. Thank you for doing it on the smartctl output.

Your SMART test results look fine.

Since you hadn't run any tests and just did the short test, I'd run a long test on all of them. The long tests will take a couple of hours to run.

Do you run scrubs? If you don't know, we'll be able to see the last time one was run, if you post the output from zpool status.

I don't run scrubs, i didn't know what they were until my USB boot stick had an issue (separate thread). I did click the scrub button a few times in the past but couldn't work out what it was doing- looked to do nothing.
I've requested a full smart scan, and it said come back in 401 minutes so I'll post the full scan results tomorrow.

Here is the zpool status result:

To answer your earlier question, you have 2 sets of mirrors that have been striped together to form a volume (vol1).

For many use cases, it's recommended. And, you have the ability to grow your volume easily, by adding additional sets of mirrors. You pay a lot for overhead, since you lose one drive per vdev. And, if both drives in a mirror were to fail, you'd lose your entire pool.

Many users use RAIDz2, which with 4 drives, which would offer the same amount of storage that you currently have. But, with RAIDz2, you could lose any 2 drives, without data loss. Since you're giving up the equivalent of 2 drives for parity, the sweet spot for RAIDz2 is 6 drives. Unfortunately, you can't switch from what you have to RAIDz2 without backing up your data, rebuilding your pool and restoring the data.

The freenas is set up as 4x 3T Discs, in some configuration that gives me 5.5G usable disc space, i cant see how you can see what the raid method is and i cant remember what i set.

See section 8.4 of the documentation (http://doc.freenas.org/9.3/freenas_storage.html#scrubs) to read up on scrubs. In addition to running SMART tests on a regular basis, you should also schedule scrubs to run.

Looking at the output of zpool status, we can see that there are some problems with your boot media. zpool status -v would display the files that have data errors.

I recommend that you reinstall FreeNAS on a new flash drive and restore your configuration to it. If you don't have a backup of the latter, create a backup now. You can do it via the GUI - System→General →Save Config. You'll be able to restore the settings using the GUI too.

If you are using encryption, you'll need additional information.

Darn, i thought i'd selected Raid-z2. I'll need to borrow a 3T drive from somewhere now to convert it :(

OK, so this issue didn't go away, i just forgot about it! I checked freeNAS yesterday and i had an alert that said "Device: /dev/ada0, 1 Currently unreadable (pending) sector", so I ran long smart tests on all drives overnight.
Here is the output of -a /dev/ada0 for all drives:

If Selective self-test is pending on power-up, resume after 0 minute delay.


Any ideas? I don't know what these figures are trying to tell me?

I see, this is an error. Is this a serious error? e.g. will i need to RMA the drive? It is a WD red and has a 5 yr warranty.

Raw_Read_Error_Rate is not zero like the other 3 drives too, is that a drive failure?

I world try to replace it, especially if it was under warranty.

Ok thanks. Will the NAS still work while the drive is out or should i shut it down until i get the new drive?

If WD warranties it just have them send you a new drive and keep using the nas. Just keep an eye on it.

If you can't get a warranty replacement for a single pending sector, consider purchasing a spare. Burn it in, then keep it on the shelf.

A single pending sector is no big deal, but if the count starts to rise, replace the drive.
