SOLVED Matching GPTID and Disk Serial Number

[Raggou]

Hello,

I have replaced disks in Truenas before but for some reason my brain isnt working properly and Im having a heck of a time identifying which disk has failed here.

Code:

root@truenas[~]# zpool status -v

  pool: BigPool
 state: DEGRADED
status: One or more devices has been removed by the administrator.
        Sufficient replicas exist for the pool to continue functioning in a degraded state.
action: Online the device using zpool online' or replace the device with 'zpool replace'.
  scan: scrub in progress since Mon Sep 5 13:29:55 2022

I dont see the removed GPTID anywere listed? Am I blind how can I match gptid/707a101f-646e-11e9-8739-ac1f6b251ca2 REMOVED to a drive/serial number?

Thanks

Your disks.sh output looks funny. Can you report on midclt call disk.label_to_dev_disk_cache | jq?

I figured out the issue. Ada7 was the disk that was removed/offline. I was able to match what serials were reporting vs which ones were not reporting. I basically forgot to count to 7. All set now and replacement disk is online and resilvering
