TrueNAS Scale, hard disks, and pools (piefed.social)

I'm trying to run a load of services and use TrueNAS Scale as the data storage for them. I have three 1 TB disks setup as RAIDZ1 - a single data pool. I've had to unplug the power a few times for various practical reasons and it seems like this setup simply cannot be relied on to function. Sometimes it's fine, sometimes it's not. I feel like I'm taking crazy pills here and cannot for the life of me figure out what I'm supposed to be doing.

I take a look at the storage dashboard and see "Unused disks: 3". Okay, let's add them back to my pool ("main"):

Add Disks To:

New Pool
Existing Pool

...except there's no pools listed under "existing pool". If I create a new one it just wipes the disks. That's no bloody good.

Thankfully I've yet to store any important data on them as I'm still in the testing phase. As far as I can see though, despite the disks being attached to the system by serial number, it gets confused and doesn't keep them through power disruptions.

Is it worth fannying about with TrueNAS? I feel like I might as well just bin ZFS and use an rsync-based backing up of data (I have several other disks, but only three that are the same size).

Have been using TrueNAS for 13+ years since the FreeNAS 9.x days. Can attest to its bulletproof-ness in my case.

Would second asking in the iX forums. I've managed to get replication help directly from iX staff before when using the forum. You shouldn't have this issue, and you will find answers.

I've moved my disks to a completely new machine with fresh install and then import my config, reboot and everything is as it was. I've also done the same without my config and imported the pool with no problems, just need to recreate shares, and any jails (a feature which I no longer use) would need to be reconfigured to be 100% functional.
