Thanks, that appears to have done the trick! Now going at about 1% every 12 minutes (so should complete in 20 hours!) Do you know if there is a risk to the whole array if I leave write cache enabled? Or would it just be a case of the files being written (e.g. currently being moved by mover) becoming corrupted in the event of power failure?

Thanks for looking! Not much more to add than its: N54L HP Microserver AMD Turion II Neo Dual Core @2.2Ghz 8GB RAM (RAM usage around 13%).

Thanks, log attached. tower-diagnostics-20200802-1807.zip

I am trying to use the parity swap procedure to upgrade my parity disk from a 2TB WD Green (5400RPM) to a 4TB WD Blue (WD40EZRZ, 5400RPM, CMR). Using the old 2TB drive to replace a data disk with SMART errors. This is on an N54L microserver with the AMD Turion II Neo Dual Core @2.2Ghz. Unraid was just upgraded to 6.8.3 from 6.1 prior to starting the swap. I started the array copy yesterday but it has only done 17% in 26 Hours. CPU usage bar sitting around 60% with one core sitting near 90%. Is this expected? I know this isn't the fastest hardware, but surely it shouldn't take a week to copy 2TB? Is there any way to do this faster? If it is a CPU issue can I take the drives out and do the copy (e.g. with dd) on my desktop? Thanks in advance!
