Mixed VDEVS no redundancy

TrueNAS General

I have 2 discs in 1 pool, and 1 disk is 2Gb, while the other is 1Gb. This 1 Gb was the original only disk for my CCTV recordings, It went faulty, ie failing smart tests, so I bought a new 2Gb disk. After i set up the 2Gb disk I then wiped and formatted the 1Gb disk in my linux machine, and then added it to the 2Gb pool.
I added a vdev for the new 2Gb disk, then added another vdev for the 1tgb disk, but now I get a orange exclamation against data VDEVS.

Can this be fixed or do I have to live with it.
Thanks

The orange warning is simply telling you what you already know - that you have the most unsafe configuration possible.

By striping two non-redundant vDevs together you have made your pool twice as likely to fail as a single drive - a redundant configuration would be safer, not less safe.

However, since this only contains CCTV recordings that you can (presumably) afford to lose entirely, this appears to be a risk that you know about and have accepted - in which case the orange warning symbol can be safely ignored.

Ok thanks for the reply, but how do I do I make a redundant configuration for the said pool.

Buy another 2TB and another 1TB disk and add them as mirrors to the relevant vDev.

I would if I had the money, but I don’t at the moment.
I’ll just leave it as is until something goes wrong.

thanks anyway

Just make a Mirrored Pool, no Problem. Choose “Mirror” for the Layout at Stage 2 of the Pool creation process. Your available Storage capacity will be 1 GB until you change out your disks.

Ok - just so long as you realize that when something does go wrong, then most likely the entire contents of your pool will be gone.

Fair enough, but when it does, I’ll wipe the disks and start again with just one VDEV

If it’s security camera footage the risk is different inasmuch as the recordings are almost certainly going to get deleted anyway, based on a set time limit. Or maybe even sooner based on a storage limit.

Hopefully it’s still just security footage?

Yes it is just CCTV recordings for my home. For me it’s no big deal if everything does get deleted, as I would just start over with both disks this time.
