August 25, 20205 yr SCRATCH THAT: I think it was a false alarm. I noticed the "File Integrity" plugging was running at the same time on the same schedule. Talking about bad timing. I disabled the file integrity process and started parity all over after rebooting the box. I will keep you posted what I get in terms of performance. On 55MB/Sec now Man now I am scared. System seems to be rock solid no errors or anything. This is my first scheduled parity check after the system was built and I only get 13 MB/Sec. I will be at this fir 10 days Anything I am missing or done wrong? I did attach the diagnostics file and few screenshots. I would really appreciate the help and guidance As background, the initial parity check on this was around 120/MB/Sec so I know the box can do it and the setup/hardware is right and the same Thanks nas-unraid-diagnostics-20200825-1123.zip Edited August 25, 20205 yr by johnwhicker
August 25, 20205 yr It should be quicker than that in my opinion. I made a check yesterday and it was much faster. Are there file transfer going on at the same time ? Do you have a rough idea of the usual read or write speed on the Array ?
August 25, 20205 yr Although, you seem to have a low power CPU with one thread maxed out from unraidd0. I don't know if the Parity check is multithreaded, maybe this could be the issue ?
August 25, 20205 yr Community Expert There was something reading from disk2 when the diags were saved, any array activity will slow down the parity check.
