For a while I used regular raid on OMV but then decided to switch to snapraid. One of advantages I heard was that the parity drives can spin down in snapraid.
But in regular raid they need to be spinning all the time. I currently have 4x8tb drives that I have encrypted and have set up with snapraid. I am using union filesystem as well, I have set up 2 drives as my main storage 14.55tb. Also with the 2 last drives as parity 14.55tb.
I am not very experienced with snapraid but I am wondering if I have done this setup correctly, and also how does snapraid store its parity. In the event of a hardware failure on my main storage, how do I recover my files that's in parity?
