To be honest after watching some videos about zfs, I'm still not sure how it works! so i don't understand how that would be too much redundancy XD. is that setup inefficient because i have a few drives?
would you say it's better if i just go with RAIDZ 1 and then if for some reason needed that feature i should make a new pool with RAIDZ2 and just transfer the data?
Maybe I'm overthinking this
There is no such thing as to much redundancy, I am simply suggesting you would have to have a really unfortunate situation where a mirrored array failed (as in, just two drives, each a mirror or each other).
RAIDZ2 with only 3 drives is very expensive per GB of usable capacity, since you’re paying 3x the cost of each usable GB. My array being 10 drives with 2 drives of redundancy means I paid 1.2x the price. There is nothing inherently wrong with your plan, it’s just very expensive for not much usable space. Think about it this way, if you spend 150 per drive, you will get 8TB for the price of 450 bucks. If you spend 600 bucks, you will literally double your capacity to 16TB… or if you spend “just” 300 more (which is only 66% more money), you would 3x your capacity.
But, if you want to buy just three drives now, set up Z2, and hope the new ZFS feature to add drives does actually happen, then it’s not a bad idea. But, if that never happens, then it was probably a pretty bad idea.
It’s a bit of a gamble you are taking, but buying more drives now is a better long term financially good option, since you can spend 66% more money and get 300% the space for instance.
