What the smart message mean?

[Fei]

Hi

Today, I upgrade my freenas to 9.3.1 latest , the system show critical alert after reboot.

Code:

[root@160nas] /usr/local/etc# cat /var/log/messages |grep smart
Apr 13 00:20:03 160nas smartd[2586]: Device: /dev/ada4, FAILED SMART self-check. BACK UP DATA NOW!

Apr 13 00:20:03 160nas smartd[2586]: Device: /dev/ada2, 2 Offline uncorrectable sectors

I check my pool , it don't have any problem,so what the message mean?

Code:

ada2 and ada4 are starting to have bad sectors. Usually a few bad sectors isn't a problem but if the number rise you'll want to replace the drives ;)

However as you have a RAID-Z1 you can't afford to have two drives failing at the same time so replace ada4 (as it seems in a worse state than ada2) before it's too late. I hope you have a backup of your data just in case.

The output of smartctl -a adaX for each drive would be useful to be more precise/confirm the answer :)

I check my pool , it don't have any problem,so what the message mean?

The messages mean exactly what they say: ada4 has failed a SMART self-test and has too many reallocated sectors, and ada2 has two offline/unreadable sectors. You need to replace ada4 immediately, and should keep an eye on ada2. There's no reason you should expect that this would show up in your pool status--it could, but it's also possible that the bad sectors are in locations with no data at the moment.

Hi

I running samrtctl -a ada2 & ada4 .

 

[Bidule0hm]

Ok, ada4 is failing hard, almost 2k reallocated sectors...

No SMART test has ever run on these drives; did you setup the tests in the web GUI?

Then I wanted to know why two drives with less than 6k POH are failing when I saw that: 194 Temperature_Celsius 0x0022 082 080 000 Old_age Always - 70 I can say you're probably the winner of the hottest drives I saw on this forum... The drives should be kept under 40 °C, note that 5 or 10 °C more is very concerning and yours are 30 °C more than that... You should stop the server right now and re-think the thermal design because with a 4x 3 TB RAID-Z1 you'll probably loose your data more or less soon.

Next time you post SMART results, please just post them inline in code tags, rather than as attachments. Other than that, what @Bidule0hm said--you've got major problems:

• You're cooking your drives. You need to get your server out of the attic, get proper airflow, and get the drives cooled right down. Point a household fan at the server, if that's the best you can do. It may be too late for the drives that are in there, but it'll still pay dividends for the replacements.
• You need to configure the SMART service to email you alerts, and to warn at a sensible level (i.e., not more than 40 C) for temperature.
• You need to schedule regular SMART tests, as these drives have never seen one. I run a short test daily and a long test weekly; you could go as long as a short test weekly and a long test monthly.

Run long SMART tests on all your drives ('smartctl -t long /dev/adaX'). Once those finish (about 6-8 hours), post the results of 'smartctl -x /dev/adaX' for each drive, inline, in code tags.

When I running 'smartctl -t long ' test ,How to check this test is done ?

 

[gpsguy]

If you run smartctl -a /dev/adaX

and look at the summary info near the end, the test will say completed if it's finished.

Hi

I power-off my freenas and add a internal SAS HBA to enhance disk I/O(3Gb -> 6Gb) , so fail disk number was change.
ada2 -> da1
ada4 -> da2

Code:

Apr 13 11:38:52 160nas smartd[8655]: Device: /dev/da2 [SAT], FAILED SMART self-check. BACK UP DATA NOW!
Apr 13 11:38:52 160nas smartd[8655]: Device: /dev/da2 [SAT], Failed SMART usage Attribute: 5 Reallocated_Sector_Ct.
Apr 13 11:38:52 160nas smartd[8655]: Device: /dev/da2 [SAT], previous self-test completed with error (unknown test element)
Apr 13 11:38:52 160nas smartd[8655]: Device: /dev/da1 [SAT], 2 Offline uncorrectable sectors

Smart test result as below, I found many error so I will replace these disk .

Code:

Run long SMART tests on all your drives ('smartctl -t long /dev/adaX'). Once those finish (about 6-8 hours), post the results of 'smartctl -x /dev/adaX' for each drive, inline, in code tags.

Edit: A SAS HBA certainly won't hurt anything, but it won't really benefit you when using spinning rust. We already knew that da2 (the former ada4) was bad, and now it has a failed SMART self-test to confirm it. da1 (the former ada2) doesn't look too bad except for the temperature.

Hi danb35

If da1 smart test is normal , so I can ignore da1 error message from Web Gui (Alert System) ?

Code:

/dev/da1 [SAT], 2 Offline uncorrectable sectors

Two offline sectors doesn't (IMO) mean the drive needs to be replaced right away, but you should keep an eye on it. If the number starts climbing, you'll want to replace it.

Your last SMART results show the temperatures are lower, but still way too high.

Thanks your response .
The temperature issue I will improve it.
