1 xazz Posted January 27, 2020 Author Share Posted January 27, 2020 From my reading elsewhere on the forum, i see that i should have enabled the "Duplication Space Optimizer" balancer. I will do that now and let you know how it goes. vfsrecycle_kid 1 Quote Link to comment Share on other sites More sharing options...
0 Christopher (Drashna) Posted February 3, 2020 Share Posted February 3, 2020 Yup. It looks like you have 2x 8TB drives, and the difference in usage is about 1.5TBs. That would definitely cause this to occur. And over time, it should resolve itself. Quote Link to comment Share on other sites More sharing options...
0 xazz Posted February 5, 2020 Author Share Posted February 5, 2020 Yes, sorry, it has resolved itself. I turned on the "Duplication Space Optimizer" balancer and after several balances over the last week "Unusable for duplication" is now zero Quote Link to comment Share on other sites More sharing options...
