Pools offline after power outage

[icemule1]

My power went off today and when it came back on I turned my TrueNAS server back on, but the pools are offline. Any idea what happened here?

Saw these messages in notifications:

Code:

CRITICAL

CRITICAL
Pool Scratch state is OFFLINE: None
2023-02-23 16:31:49 (America/Phoenix)

Here are some CLI outputs if it helps?

Code:

As both your pools are single-disk, they automatically went offline when their respective disks lost power. Try reimporting them via the UI; they may still be OK.

You may also want to invest in a UPS to have a clean shutdown during the next power bump.

One pool actually has 6 disks. Is it normal for the pools to go offline when the server loses power?

It's not uncommon.

I was able to bring them back online using zpool import, thanks.

Glad to hear your pool is back and your data is OK.

Did you need to use the command-line interface to import the pool, or was it doable through the UI?

 

[icemule1]

It wasn't doable through the UI - in the dropdown where I needed to select the pool to import, it wasn't giving me any options there. So I had to resort to doing it through the command line interface.
