Help with degraded pool

[joncy92]

Hello,

I have a pool made up of 3 mirror vdevs and all three mirrors are showing degraded. Only one of the disks has smartctl errors though.

Here is the latest zpool status after I've run a scrub...I've listed the dev name next to the disk line:

Code:

root@truenas[~]# zpool status -v
  pool: Nasuni
 state: DEGRADED
status: One or more devices has experienced an unrecoverable error.  An
        attempt was made to correct the error.  Applications are unaffected.
action: Determine if the device needs to be replaced, and clear the errors
        using 'zpool clear' or replace the device with 'zpool replace'.

Here's the smartctl results for each dish on pastebin:

Are there issues with any disks bar ada2? Does ada2 need replacing asap or does it have some life left? Why do the other mirrors also show as degraded?

Thanks

your WD80EFAX are SMR drives which won't be helping.
how are your drives attached ?

WD80EFAX are SMR drives

I don't know about that... I don't think WD made 8TB REDs in SMR.

List of known SMR drives

Hard drives that write data in overlapping, "shingled" tracks, have greater areal density than ones that do not. For cost and capacity reasons, manufacturers are increasingly moving to SMR, Shingled Magnetic Recording. SMR is a form of PMR...

For sure there's a problem with the controller (either it can't work with all the drives or it's broken all on its own).

I don't visit pastebin links in this forum anymore, so can't comment on your drive SMART status.

OK, but they are running a bit warm at 50C

All the drives are CMR

They are directly connected to the board with SATA
