April 3Apr 3 Hi,I am having issues with my unraid server freezing up during parity checks.I am unable to connect to the gui from my pc, no service running on the machine is accessible and if I attach a monitor directly to the system, it still shows the login screen but does not take any input whatsoever. I need to force a reboot by holding the power button or removing the power cable.So I already had issues with the server randomly freezing up which I attributed to my flash drive dying. I switched the drive on the 7th of March and while I was at it, I also switched cpu, motherboard and case.Currently running the following drives (incase this is of help):Parity 1: 8TB (refurbed)Parity 2: 8TB (refurbed)Data 1: 2 TBData 2: 2 TBData 3: 2 TBData 4: 8 TB (refurbed)Cache: 1 TB SSDIntel N10016GB DDR5 4800ASM1166 NVME to SATA Adapter.Everything was running fine for about a month. No Freezes. In the night from the 31st of March to the 1st of April it froze again. Since then it froze every night. From the Logs I believe it freezes during the parity check. But I am not able to identify the cause of it.I tried to use AI to assist me since I am not experienced in going through the diagnostics but every fix it suggested did not work at all.I tried plugging all but the cache drive into the mainboards sata drives instead of the nvme to sata adapter I have.Tried disabling ASPM.Even installed Mover Tuning Plugin to avoid the mover being run during the parity test. I am out of ideas and even the AI suggested to post in the forum (I did not expect it to do that at all lol)I am thankful for any ideas you guys might have.I have attached the diagnostics file as well as the syslog file from the 31st till today (Minus a few lines that is just the mover moving a bunch of files).nas-diagnostics-20260404-0024.zipsyslog.txt Edited April 3Apr 3 by Mitsch1
April 4Apr 4 Community Expert I'm afraid there's nothing relevant logged suggesting a hardware issue. Parity check/sync will put more stress on the system, making any issues more visible. RAM or PSU would be good places to start.
April 4Apr 4 Author Well that was what I wanted to hear the least. Thanks for taking your time!I am going to start a memtest now and see how it goes. What would you suggest on how I go about testing the psu? Its a new one I bought for the build and I dont have another one laying around to test out unfortunatly and I have never tested a PSU before.
April 4Apr 4 Community Expert The easiest way would be to swap the PSU with another PC and test, if available.
