August 17, 20187 yr Hi All Pulled a 500GB HDD from the array yesterday and replaced with a new 4TB WD Red. I followed the parity swap procedure (old parity was a 3TB red). It copied the parity over to the new 4TB and is now rebuilding the array with the old 3TB taking place of the 500GB I pulled. Rebuild speed seems very slow though and seems to be maxing out at 30MB/s which seems pretty slow to me. Diagnostic report attached Thanks nas-diagnostics-20180817-1346.zip
August 18, 20187 yr Author Update - rebuild completed @ an average of 35MB/s Started a parity check which is happening at ~120MB/s which is more what I'd expect. Send write is the limiting factor. I'm on a N54L microserver so may check write cache I'd enabled
