Disk Unavailable ... but which disk?

[Ruff.Hi]

I rebooted my server and got a 'Pool Degraded, disk unavailable' error. That error has now cleared itself and Pool Status shows no issues but did just run a resilver.

My post here is because of the identity of the disk ...

Code:

New alerts:
* Pool DuffleBag state is DEGRADED: One or more devices could not be opened.
Sufficient replicas exist for the pool to continue functioning in a degraded state.
The following devices are not healthy:
Disk 9143478264579565473 is UNAVAIL

Which disk is that?

I can grab the following for my disks ...

Code:

+========+============================================+======================+======+
| Device | GPTID                                      | Serial               | Skip |
+========+============================================+======================+======+
| ada0   | gptid/bb7e2890-fbcc-11e9-abbe-0cc47aac270a | AA000000000000001009 |   N  |
| ada1   | gptid/bb84c298-fbcc-11e9-abbe-0cc47aac270a | AA000000000000001549 |   N  |
| da0    | gptid/fa407967-57af-11eb-a9c6-ac1f6ba054d6 | WD-WCC7K5FTSETR      |   N  |

but nothing that reports a 91 x 10^? type number.

My NAS drive emails everything to a dedicated gmail account ... and if I search for 9143478264579565473, it only finds two emails from today (new alert, cleared alert).

I'm not that worried (at the moment), but how to I find disk 9143478264579565473 if / when it does fail?
Or is this a general error (warning ... see pool status for actual disk) type situation?

Look at zpool status -v

Or go to the pool in the GUI, click the cogwheel on the right and select Status...

Then you will see which disk it is by gptid.
