S.M.A.R.T. error - Time to RMA the disk? - Help a noob

Hi all,

Got the message: " Device: /dev/sdd [SAT], 1 Offline uncorrectable sectors."
and disk failed a S.M.A.R.T. test, time to replace? Do another LONG test and pray?

Thanks for your advice.

Here’s the full log:

Realised it looks horrible, here’s in screenshots:

It only has 1 pending sector. If it’s still under warranty, yes, you can replace it likely they will do so with pending sectors. If it’s not under warranty, I likely would not for 1 bad sector as ZFS would have corrected it. I would however make sure you have ongoing smart tests, and, scrubs. Myself, I’d just monitor it for further issues. I can take a few pending sectors without worrying much about it. Assuming you have parity that is, like raidz(1-3) or a mirror?

If it’s running 24/7 with no spindown, that’s < 1 year old so should be warranted. However, I also note you have a load cycle count of 29,591 which is quite a bit in a year. My seagate with about the same number of hours of usage has a count of 2,597. Here is a reference thread if it’s the same issue:

Likely the count isn’t a problem at all for those types of drives, but you can check the rated lifetime for that drive with Seagate.

The best solution is to use the </> button, or to paste the text between two lines of three backquotes.

```

```

But the drive is due for RMA. One sector is not much YET, but failing a SMART test is terminal.

Thanks,
I think I’ll monitor while I figure out if I can RMA and will certainly look at the cycle count issue. Not sure if being set up as a time machine and (low usage) Plex server can do that to cycle count. I’ve compared to its mirror and shows the same.

6

Thanks for the tip!

Looking at RMA, should be in warranty.

7

It’s not really an issue unless the drives cycle count limit is not very high. If it’s half a million, doesn’t matter. If it’s 100k, you are almost 1/3rd there already. No, Time Machine or Plex will not do that. It’s likely a drive power saving feature. But it may not matter, check the limit, then decide.

If it’s under warranty, definitely RMA it. There is no harm and if the drive gets worse, better now than later.

8

Thanks!

Also, as an add on question for everyone…

My pool was a 2 disk mirror, can I take the disk offline and out of the system (to RMA) and continue using the remaining disk normally while I wait for my replacement?

9

Yes, you can. For the sake of redundancy, though, see if you can do an advance exchange. Get the new drive, burn it in, resilver it into the pool, then send back the old one.

10

The system will run fine. As Dan mentions, the problem is you have no redundancy in the meantime, so, any parity or other error can mean loss of data. This is why I keep a drive on hand for my system, so it can be replaced as soon as possible. A hot spare if you have ports for it. As he says, see if you can do an advance replacement for this reason. And if you can afford it, keep a spare drive on hand.

11

I’m looking at at least a month given where Seagate wants me to send the disk, I’ll try getting another one, even if I have to buy it outright, though.

12

Yeah, which is why I keep a spare on hand. In my case, it is a hot spare. I will not go a month without any sort of redundancy. But not everyone can swing it.

If you decide to buy one, you’ll have that spare when they (eventually) send the replacement.

Mostly for price-to-capacity ratio convenience I have a mirror (2 large disks). Since I might end up with 3 by buying one ASAP, would you suggest a three way mirror or a raidz1?

14

Or keep my 2 disk mirror and a spare as you suggest… I do have the bays to put it in though.

15

My choice, with little info, is mirror with spare. If you convert to a raidz1 by moving your data off and back, you would still want a spare, and therefore then a 4th drive.

Think of the situation you are in now. (same if it was a raidz1). If some time in the next month this drives fails, you lost everything. Waiting a month carries some risk of that.

No matter how you use the drives, which raidz, etc, you still need backups. So, hopefully you are backing up your data unless you simply don’t care if you lose it.

Mirror + cold spare is the most natural choice.
With several vdevs you could consider a hot spare; with a single vdev there’s no point in a hot spare over a 3-way mirror.

Thanks everyone.

Conclusion is I ordered another disk and RMAing the faulty one today, I hope I can go without redundancy for just a few days.

If you’ll indulge me, here’s a last question for you all. Easy enough to take the disk offline and exctract it for replacement. Is there any way to also wipe it straight from truenas? Should I move it to another system and do it there?

I want to wipe it before sending it in to RMA.

Thanks again!

18

You could wipe in on the TrueNAS machine however I would recommend putting the drive in a different machine to wipe it. Without redundancy, why take the risk of screwing it up.

19

Great! Exactly my thought, wiping and sending it out today.
Thanks
