Got this email (twice at exactly the same time) last night:

This message was generated by the smartd daemon running on:

host name: freenas
DNS domain: local

The following warning/error was logged by the smartd daemon:

Device: /dev/ada1, Self-Test Log error count increased from 0 to 1

Device info:
WDC WD10EFRX-68PJCN0, S/N:WD-WCC4J3542112, WWN:5-0014ee-25f5645f2, FW:01.01A01, 1.00 TB

For details see host's SYSLOG.

You can also use the smartctl utility for further investigation.
No additional messages about this problem will be sent.

Since then, I've run a short test, and a long test is currently running on ada1. Here is the bottom bit of the output of smartctl -a /dev/ada1 ( I don't know how to scroll up within the shell window...)

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


Where do I go from here?

If you ssh to the machine rather than using the Shell button from the web GUI, you'll usually be able to scroll back and capture everything. Or you could "page" the output, so you could read it all, by doing "smartctl -a /dev/ada1 | more". Or you could send the output to a file on your pool by doing "smartctl -a /dev/ada1 > smartinfo.txt".

But all of those aside, your drive appears to be failing. If the long SMART test you're currently running also shows an error, I'd RMA the drive if under warranty, or buy a new one if not, and replace it.

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


So that's the full smartctl -a /dev/ada1 | more output. The second extended SMART test passed, so where does that leave me? Is the drive failing or did it just have a funny few minutes? Setting up SSH is something I have been meaning to do.. this may convince me to get round to setting it up and making sure it's secure

The drive has (at least) one crappy sector. Just bad enough to trigger a read error but not bad enough to be reallocated. See the description text of the ID #197 on this table ;)

At your place I would keep an eye on this drive.

Okay so to bring this thread back - Since this error, I've had no issues with the drive. Until yesterday morning; I got this email

"This message was generated by the smartd daemon running on:

host name: freenas
DNS domain: local

The following warning/error was logged by the smartd daemon:

Device: /dev/ada1, Self-Test Log error count increased from 0 to 1

Device info:
WDC WD10EFRX-68PJCN0, S/N:WD-WCC4J3542112, WWN:5-0014ee-25f5645f2, FW:01.01A01, 1.00 TB

For details see host's SYSLOG.

You can also use the smartctl utility for further investigation.
No additional messages about this problem will be sent."

So to start with I thought it was a different drive, until I pulled up this old thread again. Realised it was the same one, The results of "smartctl -a /dev/ada1 | more" this time round are as below:

Is this drive getting worse? I am not comfortable reading/interpreting the SMART results. So far this time round, I haven't run anything. By default I do weekly long tests, and daily short tests. As well as monthly scrubs.

Well, the SMART test failed, so it should qualify for an RMA.

We need a bit more clarity here. Could an expert please apply their minds?
(1) Agreed it has passed SMART. It says so.
(2) It has (a) read failure(s). A "read railure"
What does this sum to, though, in terms of say Freenas (and ZFS) in relation to say other systems?
Is it a disk that is really about to fail or is it just now performing well enough for ZFS?

Unless you enjoy philosophical discussions about the existence of data once it was stored by cannot be read... A bad disk.

Yes - "to be or not to be data" isn't going to help much ;)
The point is how to make sense of:
"SMART overall-health self-assesment test result: PASSED"
but
then a "read failure"

SMART overall-health is just about the SMART attributes, it will only fail if one or more attributes are failing NOW, it doesn't even consider for example a few pending secters, not a good way to access a disk health, SMART extended test is a much better way of determining if a disk is good or not, sometimes together with analyzing some SMART attributes.

Johnnie Black - thanks.
I'm wrestling with the the fact the 3 and potentially 4 disks in my system have gone bad. I'm posting here the results of all SMARTs and Zpool status. I'll also give the hardware profile at the bottom. The system (this particular pool) has been running without obvious glitches for over 6 months before dying in a fairly epic fashion.
I'd really appreciate your view on the disks and whether this really is a horrible batch of disks or whether something in my system could be underlying this mess.

I've attached the smart long test results for the four disks.

This last disk was in the array but it faulted so I burned in a new disk, replaced it and started what I hoped was going to a smooth resilvering process (before the 2nd and then 3rd disk started to give problems). I put this disk in another linux machine to re-run smart (to make sure something weird isn't happening in my FN system.


The result of zpool status shows:

They are all failing, some attributes to keep an eye on WD drives are, besides the more common pending and reallocated sectors:

Code:
  1 Raw_Read_Error_Rate     0x002f   200   200   051    Pre-fail  Always    
200 Multi_Zone_Error_Rate   0x0008   200   200   000    Old_age   Offline


Ideally these should be 0, doesn't mean that a disk with a non zero values on either or both is failing, as long as the extended SMART test completes without error the disk is good, but it's never a good sign, and if they keep increasing disk will likely fail sooner rather than later, when the extended SMART test fails the disk is failing, i.e., there are bad sectors.

P.S. it would be nice the see smartctl -x output for all, there's some more info, including logged errors and max lifetime operating temps.

Thanks for the confirmation and taking time to look.
I am trying to get understand this problem. They are not dead as per smart -- yet - but are on the way to the grave. Yet Freenas has marked two of them as faulted. That renders them essential unusable, I guess?
I see the faults seem to cluster around a short period of time (45x hours). I presume if these were all at same time then it would some physical knock to the system. Otherwise does this just look like a bad batch?

Extra infomation is attached.

Click to expand...

In fact with cases like these, especially when there aren't pending sectors, it can sometimes happen the bad sectors being intermittent, i.e., if you run a couple of extended tests more it might pass again, and the disk can even be good for some time, but in my experience it's more likely to keep failing or fail again soon.

Historic max temperatures are good, so you either you had bad luck or there was some other external factor at play, like high vibrations, power issues, etc, most likely just bad luck.

Thanks for the input. I've sent the 4 WD drives back under warranty. The 3TiB were replaced with 4TiB. So I don't know if the 3s were known to be troublesome.

Funny thing, yesterday I enabled SMART testing for all disks in my system. 2 of them are WDC WD30PURX-64P6ZY0 WD Purple 3TB.
They were never used, just powered on for 1-2 years. So all critical SMART data is at 0.
Nevertheless, today I was greeted with the same errors as OP for both drives:
# 1 Short offline Completed: read failure 40% 11115 9655736
# 1 Short offline Completed: read failure 40% 5150 590976
This coincidence makes me think that there are some bugs with firmware and maybe we shouldn't trust the test results. Why would these drives fail the test without any usage?

edit: after further investigation it seems the sectors are bad indeed. i get read errors with sg_verify. glad i didn't use these drives.
