You can try reblocking it with a sequence of fill level percentages: hammer reblock <fs> 10 hammer reblock <fs> 20 hammer reblock <fs> 30 hammer reblock <fs> 40 hammer reblock <fs> 50 hammer reblock <fs> 60 hammer reblock <fs> 70 hammer reblock <fs> 80 hammer reblock <fs> 90 Each PFS needs to be independently reblocked. -Matt
