September 6, 20214 yr Hi there, today I was copying some files from my server when the computer just hung up. Never experienced something like this before (see image attached 'index'). After this, I rebooted the computer and unraid started correcting sectors. I have lots of errors (millions, see the image below) I suspect my files are OK and parity is wrong since all disk are almost new and there are no SMART issues. Maybe my memory bank is the problem but, how to check if file integrity is OK? In other words, could I check what files are incorrect? Most of them are photos so it would be easy for me. Some logs: Sep 6 18:44:43 Fractal kernel: md: recovery thread: P corrected, sector=9156616 Sep 6 18:44:43 Fractal kernel: md: recovery thread: P corrected, sector=9156624 Sep 6 18:44:43 Fractal kernel: md: recovery thread: P corrected, sector=9156632 Sep 6 18:44:43 Fractal kernel: md: recovery thread: P corrected, sector=9156640 Sep 6 18:44:43 Fractal kernel: md: recovery thread: P corrected, sector=9156648 Sep 6 18:44:43 Fractal kernel: md: recovery thread: P corrected, sector=9156656 Sep 6 18:44:43 Fractal kernel: md: recovery thread: P corrected, sector=9156664 Sep 6 18:44:43 Fractal kernel: md: recovery thread: P corrected, sector=9156672 Sep 6 18:44:43 Fractal kernel: md: recovery thread: P corrected, sector=9156680 Sep 6 18:44:43 Fractal kernel: md: recovery thread: P corrected, sector=9156688 Sep 6 18:44:43 Fractal kernel: md: recovery thread: P corrected, sector=9156696 Sep 6 18:44:43 Fractal kernel: md: recovery thread: P corrected, sector=9156704 Sep 6 18:44:43 Fractal kernel: md: recovery thread: P corrected, sector=9156712 Sep 6 18:44:43 Fractal kernel: md: recovery thread: P corrected, sector=9156720 Sep 6 18:44:43 Fractal kernel: md: recovery thread: P corrected, sector=9156728 Sep 6 18:44:43 Fractal kernel: md: recovery thread: P corrected, sector=9156736 Sep 6 18:44:43 Fractal kernel: md: recovery thread: P corrected, sector=9156744 Sep 6 18:44:43 Fractal kernel: md: recovery thread: P corrected, sector=9156752 Sep 6 18:44:43 Fractal kernel: md: recovery thread: P corrected, sector=9156760 Sep 6 18:44:43 Fractal kernel: md: recovery thread: P corrected, sector=9156768 Sep 6 18:44:43 Fractal kernel: md: recovery thread: P corrected, sector=9156776 Sep 6 18:44:43 Fractal kernel: md: recovery thread: P corrected, sector=9156784 Sep 6 18:44:43 Fractal kernel: md: recovery thread: P corrected, sector=9156792 Sep 6 18:44:43 Fractal kernel: md: recovery thread: P corrected, sector=9156800 Sep 6 18:44:43 Fractal kernel: md: recovery thread: P corrected, sector=9156808 Sep 6 18:44:43 Fractal kernel: md: recovery thread: P corrected, sector=9156816 Sep 6 18:44:43 Fractal kernel: md: recovery thread: stopped logging More logs attached.

September 6, 20214 yr Author Hi @trurl yes, I did it for 1 hour (2 complete test) and no errors so far. I must say that 2 weeks ago I did undervolt the processor to reduce the heat. I don't know if that's something I shouldn't have done. At the moment, I'm taking out all my files, just in case I get another error. Should I rebuild my parity or leave it untouched?
September 6, 20214 yr Author Not totally. In that case, what should I do, start parity check again? Thanks Edited September 6, 20214 yr by lgb
September 6, 20214 yr Author @trurlSure. fractal-diagnostics-20210907-0029.zip Edited September 6, 20214 yr by lgb
September 6, 20214 yr Community Expert Looks like all disks are mounted. Parity rebuild followed by new diagnostics. https://wiki.unraid.net/Manual/Storage_Management#Rebuilding_a_drive_onto_itself
