ramesivi Posted May 22, 2020 Share Posted May 22, 2020 (edited) Dual parity with 28 data drives. Last two monthly parity checks averaged 140MB/s and started at 190MB/s. I recently upgraded mobo/ram/cpu, but even before that I checked parity and it was going only 110-115MB/s and stayed there the entire time. The same is happening on the new mobo/ram/cpu too. This will take an estimated 2 days for parity checks. I have tried tweaking nr_requests and md_num_stripes and it seemingly has no effect. Specs: i5 9400 ASRock B365M Pro4 2x LSI 16i SAS Cards (All 30 drives drives connected to these) 8TB drives with a few 12TB Segates Any ideas? Edited May 22, 2020 by ramesivi Quote Link to comment
