Device: /dev/ada3, ATA error count increased from 0 to 12

[willtruenas111]

Hi

I got this critical error on my TrueNAS:

* Pool RAID state is ONLINE: One or more devices has experienced an unrecoverable error. An attempt was made to correct the error. Applications are unaffected.
* Device: /dev/ada3, ATA error count increased from 0 to 12.

Does anyone have any insight as to what I should do about this or what significance it has?

I ran smartctl -a /dev/ada3 and this is the output:

Sorry, slight typo, the 2nd code block was performed on /dev/ada2 (a seemingly healthy disk) not ada3 (the erroring disk)

Hi,

This may be a drive that is about to fail but it can also be something else. I would first check the cable and port. For that, I would power off the server, unplug the cable from both drive and port, and try to plug it back in another port if you have one available.

Also, to be sure you are safe, what kind of redundancy do you have in that pool ?
And how good are your backups ?

Always better to ensure your backups are good before incidents like this materializes...

Welcome to the forums!

In addition to @Heracles excellent advice, notice that you don't have routine smart testing set up on your drives and suggest that's also worthy of your consideration. See https://www.truenas.com/docs/core/coretutorials/services/configuringsmart/

Thank you for the welcome!

I have the following set up already, but perhaps not configured correctly?

I'm not sure I have any other ports available, I have four disks occupying all the slots in a HP ge8 proliant microserver.

Re backup, the RAID pool is setup so I can lose a disk, so I'm safe if one goes, hoping that doesn't happen of course from a financial perspective!

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

My advice: Replace your drive before it dies.
So lets take a closer look: at the above data I pulled from your post. I specified the serial number (always use the serial number when tracking a drive issue).

The Reallocated sectors is 40, that is very high. This means you have a physical defect, likely the rotating platers and the medium is flaking off.
The power on hours is OVER 8 years of power on time, that is impressive! your drive deserves to take a rest.
The Reported Uncorrected is how many times the drive could not recover data.
And the last one you were already told about, absolutely no SMART tests were run.

Replace your drive ASAP ! I have no idea what kind of pool you are running but if the drive dies, will your pool die? Are you running a RAIDZ2 or a Stripe?

Regardless, the drive will need to be replaced.

 

[joeschmuck]

Also, to ensure data integrity you might run a Scrub on your pool.

Thanks for the reply.

It has indeed had quite the life, that drive, and certainly deserves a rest..

I checked the other drives who have much shorter power-on lifespans.

Fun fact: I ran a short background smart self-test just now and 'LifeTime(hours)' must be stored as a 16 bit integer. The disk has been on for so long that the number has rolled over to 5730 hours (71259 - 65535)!

I'm running a raidz1, with 4 1tb disks. That data stored isn't sentimental, but would be annoying to lose.

I checked and I have scrubs running every month, next one in 4 days.

 

[joeschmuck]

Thankfully you have 1TB drives, they should resilver fast.

Well, that's the screen in Services where you can enter HDD temperature trigger information in order to receive email alerts if things are getting toasty. You will have to decide your own tolerance to flirting with drive isues - for the three fields where you have 0, I have 10, 35 and 37, reading downwards, respectively.

But, more important, IMHO, is what you find from the link at the bottom of the page I indicated:

which takes you to a page with :

where you can configure the schedule of the testing to your liking. Standard advice has been to avoid simultaneous long and short tests and observe the scub/resilver warniong shown above; run short tests more frequently than long tests.

Here, for example, is my short schedule: Custom (0 03 05,12,19,26 * sun,mon,tue,wed,thu,fri,sat) - run on the hour at 3AM on the 5th, 12th, 19th, and 26th of any month, on whatrever day of the week those dates fall.

And my long: Custom (0 04 08,22 * sun,mon,tue,wed,thu,fri,sat) - (I'll leave you to figure that one out ...)

Hopefully that will get you started.

Unfortunately, not really... A single physical incident like water or fire will destroy the server and all its drives. The same logical error or incident will destroy the data no matter how many drives are in the server.

See my signature about backups and what is needed to protect against every single incident. The more valuable the data, the more important it is to have proper backups.

Your one of the lucky ones to have a Seagate 7200.11 drive last as long as it has. Get it replaced ASAP, they are known to be a terrible terrible drive.

 

[danb35]

Was it not of that model that @DrKK said, "the optimal configuration is buried as deep as possible in the nearest landfill"?

 

[joeschmuck]

Some people are lucky I guess.

As for one drive safe from a failure, that is all good but if you are resilvering your drive and another one dies, well we have seen it before.

If he didn't I will confirm it.

Appreciate the help and explanation.

I've now got long and short smart test tasks set up, and scrubs, at alternating times (I've also backed up my truenas config just in case..)

 

[willtruenas111]

Wow looks like I've gotten lucky with that drive.. to the bottom of the landfill it goes!

 

[willtruenas111]

If he didn't I will confirm it.

Do you have any recommendations for a 'budget' 1TB drive to replace it?

 

[Jailer]

Brand is strictly up to you but make sure you research and ensure that it is NOT an SMR drive. You want a CMR drive.
