September 3, 20241 yr Hello guys, I've been running my first unraid system for about 8 months now with zero issues until this week. I started experiencing weird unexplained crashes, where the system would just turn off and start back up by itself, do the regular boot sequence, and then about 5 seconds after it reaches the point where it shows my IP and server name.... it shuts off and repeats the loop. I've narrowed it down to an issue during parity check. Since Unraid does a check after an unclean shutdown, this creates the crash loop. I am able to recover from this crashing boot loop if I boot into safe mode and select to do a clean reboot. Then everything is fine until a parity check starts. I went to the system and booted into GUI mode, everything was up and running, I clicked "check" for parity and the exact moment I did, the system shut off. I don't mean triggers a shut down, I mean it turns off as if I just unplugged it from the wall. What do you guys recommend I look into first for troubleshooting? I have not updated my Unraid version or changed any hardware. I did check the SysLog, but there is nothing logged during this crash. Everything is normal in the log.. and then a 5~ minuted gap while its boots back up showing everything as normal. Once I do a "clean" reboot to get out of the crash loop, everything boots fine. I opened a number of Plex transcodes to stress things and it handles everything as normal. Any help would be greatly appreciated.

September 4, 20241 yr Author Thank you, JonathanM The PSU is my first suspect as well, I am actually looking into ordering one already at the very least for testing purposes. I got it to ramp up to 400~ watts with no issue though. Is the thought that one of the rails that the drives are plugged into is failing?
September 4, 20241 yr Also perform built-in memtest, you only have 4 disk doesn't like power issue. Edited September 4, 20241 yr by Vr2Io
September 8, 20241 yr Author Solution I replaced the PSU with a Seasonic 850w and my issues have seemingly been resolved.
