How to identify degraded drive

[Gasha]

Hi,
I got one degraded drive. However, I am not sure how to identify which one is bad. Here is the result of "zpool status" command:

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'.

errors: No known data errors

Image of the drive list is attached.

Since "zpools status" does not list serial numbers, how do I know which drive to replace?
Thank you.

Run the output of the SMART tests for each disk, the serial number of the drive is included with each drive's report. The report from one of your drives should have an indication of which drive is experiencing the errors:

Code:

smartctl -a /dev/adaX

One way to map the gptid's to their serial numbers is to use one of @Bidule0hm 's scripts. I believe he has a link to them in his profile. I am replying from my phone so its hard to look stuff up and provide a direct link.

Fixed that for you:

Since "zpools status" does not list serial numbers,

zpool status doesn't list serial numbers or disk designations, but the volume status page in the FreeNAS web GUI lists the disk designations (e.g., ada0). Go to the storage button in the top menu bar, click on your pool, then the volume status button at the bottom (looks like a sheet of notebook paper). That will list the disks in your pool by designation (e.g., ada0p2) and show which one is degraded. Using the designation/serial number mapping you already showed in the OP, that will let you know which disk is bad.
