pending and unreadable sectors, normal smartctl results

esamett · Sep 2, 2018

I received the following messages:
Device: /dev/da11 [SAT], 8 Currently unreadable (pending) sectors
Device: /dev/da11 [SAT], 8 Offline uncorrectable sectors

following the freenas hard drive troubleshooting guide:
https://forums.freenas.org/index.ph...bleshooting-guide-all-versions-of-freenas.17/
I performed:
smartctl -t long /dev/da11
then reviewed results:
[root@freenas ~]# smartctl -a /dev/da11 |more
with exerpt results:

I then rebooted and the error is no longer seen.

My pool and drive seem healthy but I am puzzled. What just happened??

thanks for NOOB question

That cannot possibly be the full output.

The only thing in the output to be concerned about is potentially the serial number, which we can suppress at the command line, and -x would be more useful, anyway.

Can we please see the full output of:

Code:

smartctl -x -qnoserial /dev/da11

?

Well, the SMART data shows a history of an error with the disk, but that's several thousand hours ago. Nothing appears to be problematic with the current status. However, there are a few matters of concern:

The last scheduled SMART test was 34000 hours of runtime ago--you should be running regular tests. I like a short test daily and a long test weekly, but that can be somewhat flexible.
At nearly 46000 hours of runtime, you should probably consider the disk to be fully depreciated. It doesn't necessarily need to be proactively replaced, but be wary.
You're using the shell through the web GUI, which is truly awful. An SSH connection will give you a much smoother experience (relevant to the immediate discussion, it will give you a scrollback buffer, so you don't need to pipe the smartctl output through more)

Thanks. I've never been successful getting SSH connection to work (bear of little brain)
I thought I had smart testing set up. Please help me figure out what I am doing wrong.

You need to highlight every disk you want to be tested on the schedule.

Laughing out loud... I thought I was clever and safe. Thank you my friend.

Also, just for the record:

A real careful reading of the SMART data is not quite as positive as danb35 suggested. This drive has had something like 60000 load cycles, which is surely beyond the design capacity of this lower-end Seagate desktop drive. This drive has also spent some time at nearly 60 degrees Celsius. (personally, I'd throw it out on that basis alone, but I am hard core, you should not listen to me). Finally, the drive shows just over 5 years of usage time, which, for this model, puts this into an era where Seagate wasn't doing such a great job, and for any drive, puts it into the late-middle-age/early-elderly-age category.

I agree the drive appears to be working for now, but given its make, model, age, load cycle count, and so on, I'd look for ANY reason to toss it. Having had a pending sectors warning would have been more than sufficient for me.

Just for the record.

Datasheet says 300 000 cycles, which is the same as old WD Reds and Greens. It's something I'd keep an eye on and try to fix, but not an immediate problem.

Are you sure? It's always a bit hard to tell with smartctl -a, the smartctl -x output frequently includes a nice human-readable summary of the temperature history, though.

Yes I'm sure. Says so right in the temperature summaries for his -x output.

Also, OK, fair enough on the 300000 cycles. I thought the design spec was about a tenth of that. Am I making that up?

Ericloewe · Sep 5, 2018

Ah, I stopped scrolling at the bottom post, which seems to be -a for whatever reason. Yup, the disk does say it was previously in the high 50s, which is unusual and troubling.

5900 rpm is one of the SSHD drives and it should have had the power saving BS turned off. I have never seen one of those drives that did not have errors. Great idea at the time but in practice SSHD drives are two unreliable devices with your data...

these are standard drives. toshibas I think. some desktop, some nas versions
