Mr. GMAdded a new drive to my server with the plan to make it the new snapraid parity drive and use the old parity drive for data. After copying the data over for about a day, I updated my snapraid.conf and... apparently I was only backing up 2 of my 4 (soon to be 5) data discs due to not updating my config like a year ago?
Welp, it looks like it's time for a loooong sync now that I've fixed this! I'm glad I didn't have one of the two not-backed-up drives die at least..!
