New drive failing or something more sinister (Device: /dev/ada2, 2840 Currently unreadable (pending) sectors.)

[ecreative]

Hey all,

I've recently upgraded from TrueNAS to FreeNAS, and everything was going well until I got the warning via email that one of my drives has bad sectors.

It originally started with:

Code:

Device: /dev/ada2, 8 Currently unreadable (pending) sectors.

Shortly followed by a reboot to:

Code:

Device: /dev/ada2, 2840 Currently unreadable (pending) sectors.

The interesting part was that this was a replacement drive from Seagate under warranty after the original failed within warranty.

Using the below command in the shell:

Code:

smartctl -a /dev/ada2

Which outputted:

Code:

root@freenas[~]# smartctl -a /dev/ada2

Now my bad for not enabling S.M.A.R.T tests since replacing the drive (I didn't realise I only had single drives selected), but I find it slightly coincidental that I've now had two drives fail with a low number of hours. Could it be something within my hardware setup or just bad luck?

My setup:
AMD Athlon 3000G with Radeon Vega Graphics, Gigabyte B450 AORUS PRO, 16GB ECC DDR4 RAM (I know, I need more)

I've recently upgraded from TrueNAS to FreeNAS

Maybe you mean the exact opposite?

ID# ATTRIBUTE_NAME FLAG VALUE WORST THRESH TYPE UPDATED WHEN_FAILED RAW_VALUE

Unless I didn't read the report correctly, (seems I didn't)​

can you show me where the drive fails? Because I think you were looking at the TYPE column.​

It doesn't say STATE, it explains what it means if the numbers get out of line. For example, you have 0 reallocated sectors and 0 spin retry counts.

See that it says failed: never? That is the way smartctl always outputed. In your case it is the WHEN_FAILED column. It should have a question mark, true.
What @Samuel Tai says is your last hope for the drive. You never know with replacement drives. I had a retail drive that failed in 12 months and the replacement lasted 6 and a half years, so... If SeaTools reports bad sectors, send it back (replacements have a 3 month warranty, I think?)

For Seagate drives, you have to use SeaTools to get the true picture of drive health. Seagates are known to report garbage to SMART.

We are talking about the replacement, of course, the first drive went for greener pastures...

Apologies, you are correct, I was on FreeNAS and updated to TrueNAS!

I don’t quite understand the rest of the explanation. I’m not sure how to show how the drive failed. I’m quite new to working in the shell. I’ve sent the drive off to be replaced under warranty, and just to be safe I’m going to install it in a different bay. Likely won’t make a difference, but as two drives have failed in the same bay, I’m going to see if that makes a difference.

That’s interesting to know. I’ll make sure to do that in future.
