…Not great - guessing you never setup automated Smart Tests?
You shouldn’t need the last one since it didn’t show in your camcontrol listing
smartctl -a /dev/ada0
smartctl -a /dev/ada1
smartctl -a /dev/ada2
smartctl -a /dev/ada3
smartctl -a /dev/ada4
smartctl -a /dev/ada5
Its pretty much a default install of TrueNas core, I followed instructions on how to setup a pool. But I should have done something to the drives first?
@etorix this is the status, camcontrol and then smartctl on all devices.
I’m worried by the reallocated sector count but this is mostly all new to me, and I’m learning as fast as I can.

the pool to continue functioning in a degraded state.

Use smartctl -h to get a usage summary
so ada2 has a problem?
I think etorix wanted you to run it for each drive and post it

Looking at your edited response it seems that only ada2 has a guarenteed failure. That being said it is hard to give more insight since no Smart Tests were ever actually ran on any of your drives…

Grab some replacement drives asap to rebuild redundancy. Once that is done make sure you then setup smart tests automatically using the GUI so you can know in advance before drives start dying on you!
If I were you I’d consider shutting down the NAS until you got replacement drives in hand & ready to connect.

THANKYOU.
Will do that now.
Can I just buy WD-Red or is there some other recommendation?
WD-RED or red+, Seagate Ironwolf or Exos, frankly anything that is NAS or Enterprise grade & is CMR instead of SMR is just fine.
*to clarify this isn’t a “CMR is preferred” - this is an “Avoid SMR!” If you’re not sure if a drive is CMR or SMR you can post the model # & I’m sure we can advise.

You need to go by the drives serial numbers listed on the reports you just ran. If you shut down, the device names may change. You don’t want to be pulling the wrong drives out!

So I can go by the serial #
Replace them one at a time.
I’m probably going to reply asking for help on that replacement. I didn’t do a dry run of this.
And then setup tests and alerts.
I’m guessing I should replace all of them. I guess that’s my big spend for December decided then. 
You guys have been invaluable. I’m going to read up and try to understand what I’m doing.
No guarantee on that yet. If we weren’t down both redundancy drives we’d start with some tests, but I’d personally consider it too risky at the moment… What model are the drives?
Replacement shouldn’t be too crazy, attach replacement drive, power on system, go to GUI, find dead drive in GUI, replace, select replacement drive - wait the several hours/days. Power off, remove dead drive, connect replacement, rinse, repeat.
Afterwards for all drives (separate commands, not all at once):
smartctl -t long /dev/whateverdrivename
Tests can all be done at the same time. Wait the several hours for them to finish. Then for all drives:
smartctl -a /dev/whatevername
We can read the actual results since we’ll actually have completed tests. Setting up tests:
…if we weren’t down on both redundancy drives then I’d also recommend on how to burn-in & test drives before adding them to a pool; but given the options I think it is worth the risk & to just get you back to spec first & this can be a learning opportunity in the future:
In the future before putting any data on disks make sure to test them
I’ve read three times and saw no issue with any of the drives.
As you have rebooted, drive labels have reshuffled and the former ‘ada2’ is no longer there. Always refer to serial numbers to cross-reference the drives.
This, unfortunately, is only the beginning of setting the system.
Next it is highly recommended to schedule regular SMART tests (daily shorts, weekly to monthly longs), possibly through @joeschmuck 's Multi-Report script, and, most importantly periodic snapshots.
You can launch SMART tests with
smartctl -t long /dev/ada0 (and all others…)
All at the same time. Then come back after 13 hours (± 800 minutes) to read the results (smartctl -a).
Many here stress the drives before using them in a pool (“burn-in”), but it’s not strictly required.
Wouldn’t the following confirm ada2 is fubar? (I ask to confirm my own understanding)
root@cybertron[~]# smartctl -a /dev/ada2
smartctl 7.2 2021-09-14 r5236 [FreeBSD 13.1-RELEASE-p9 amd64] (local build)

Read Device Identity failed: Input/output error
A mandatory SMART command failed: exiting. To continue, add one or more '-T permissive' options.
Considering no Smart Test was ever performance on any of them, I’d argue it is near impossible to confirm if any issues with the rest of the drives…
I went three times through this wall of text and missed THAT… (insert banging_against_wall_emoji) 
OK, so the current ada2 is to be replaced as soon as possible and binned or sent to RMA. On top of replacing the drive which has already failed.
But so far the other three look healthy.

Yep. I’ve powered down the machine, and ordered a six pack of WD-RED plus.
I’ll replace them one at a time, and then I guess wont eat for a year.

I mean, no kill like overkill. At least this way you can test the remaining drives & see if any of them are still serviceable afterwards for a second pool/backup.
Ain’t gonna stop you if you already placed the order, but you 100% went a touch hard on that.
