Disk weirdness, Faulty drive?

[platinumjsi]

Ok so a little background info, I built a new system and moved my old pool over, I set up scrubs / smart tests ect.
After the first SMART test ran on all the drives TrueNAS flagged up two drives as having read errors, I thought this was odd timing to replaced all the SATA cables to see if it was something simple.
I then re-ran the smart tests and now one of the drives passes both the short and long test and another was still failing.
I assumed this was probably faulty and planned to replace it come payday.

Today a scheduled scrub ran and Truenas picked up errors on the drive and has degraded the pool, here is where the weirdness starts though.

The drive that was still failing was drive sdg, I got this error today

So sdg error count increases and the pool is degraded, ok so far, I then checked the disks and saw this :

sdg is now one of my boot SSD's? looking at the smart results sdf is now the drive that's failing the tests, even stranger is the serial number flagged in the error is actually sdb which has passed its smart checks fine?

Zpool status output:

Any idea whats going off? TrueNAS appears to be telling me to replace the wrong drive?

 

[Redcoat]

Please post the full results of a long test on sdb.

also post results of glabel status.

 

[platinumjsi]

Please post the full results of a long test on sdb. also post results of glabel status.

Which command would I use to get the output?

I have just run a short test and it failed, could it be an issue with the new system or is it just likely that 2 - 3 of the discs are on their way out at the same time?

The disc that failed 3 smart tests in a row but is now passing them made me suspect maybe the system?

There is a UI bug that can mess up drives displayed in that section and which drives are assigned to where. Its a display bug. I sugest a reboot to ensure all is correct (which does fix (well workaround) the bug) and then investigate which drive is failing. Can't do any harm

The /dev/sd? can be a bit suspect - and which drive is assigned to which pool but glabel status does I believe provide the correct matching data

 

[platinumjsi]

Ok ill reboot, should I be replacing sdb though? seems odd to me that ones been offlined and the others are online still?

sdb is now sdc after reboot lol, so if I go to replace it will ill replace the right one? sdb pre reboot and now sdc after reboot appear to point to the same drive (SN: WD-WCC4E4XJRFY2) and the smart test results are the same)

Edit, rebooted and now the pool is showing as online, no degradation?

 

[Redcoat]

Which command would I use to get the output?

Run the long test, then smartctl -a /dev/whatever the drive id is that you used to run the test.

I note that disk is just under 6.5 years old...

glabel status should get you something like this

Then get the serial # from Storage>Disks to confirm.

 

[platinumjsi]

command not found: glabel ?

 

[Redcoat]

command not found: glabel ?

Oh - I guess you must be on SCALE?
I don't know the Linux equivalent for FreeBSD's glabel....
