DivideBy0 Posted August 25, 2020 Share Posted August 25, 2020 (edited) 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, 2020 by johnwhicker Quote Link to comment
ChatNoir Posted August 25, 2020 Share Posted August 25, 2020 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 ? Quote Link to comment
ChatNoir Posted August 25, 2020 Share Posted August 25, 2020 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 ? Quote Link to comment
JorgeB Posted August 25, 2020 Share Posted August 25, 2020 There was something reading from disk2 when the diags were saved, any array activity will slow down the parity check. Quote Link to comment
