So I did as suggested and disabled duplication. It seemed to run for a bit and got hung up on 1.7%. When looking at what it directory it was working on by hovering my mouse over my status bar it was chugging through a Plex meta data backup which was 500,000+ small files. I let it be and came back to it looking like it was complete. When I attempted to remeasure the data this is what it looks like... What should I do at this point? I have attempted to remesure the data again, ensured duplication was disabled, along with attempting to use the "re-check duplication" option. Thank you for your help!

Sorry for the rudimentary question but I searched around and couldn't find anything. I have about 70TB of media that is all duplicated across 15 or so drives. This has worked beautifully for me for the last few years. The problem is I am getting to the point that duplicating all of this media is not really feasible (or needed) with my upcoming space constraints. I was thinking about blowing it all up and using unRAID but I think I have settled on continuing to use DrivePool along with SnapRAID. My question is what happens when I disable duplication on my media? Will the space become immediately available? If that is the case my plan would be to drop duplication, remove two 8TB drives, and then use them for dual parity with SnapRAID. Also, what other relevant settings would I want DrivePool to utilize to work the best with SnapRAID? I figure that once the drives are balanced I'd want new data to be sent to a single drive until it is full as to not have the media changing much slowing down the parity computation. Any other thoughts? Thank you!
