Let's hope it sticks! I am having almost identical issues and have replaced all the hardware (except HDDs) at least once, but still it randomly crashes/reboots anywhere between 3 and 45 days. I replaced the USB stick but it did not help. Sometimes when I replaced hardware the system was stable for a few weeks, and as soon as I started to think everything was fine it crashed again. I've found no way to reproduce it manually, so I just have to wait and see...

Unfortunately I just had another reboot. This did not resolve my problem I'll replace the PSU.

Oh. My. God. I'm so glad I just now found this post! I have been struggling with random reboots on my new server, about once every second week. I've been removing one memory stick at a time and got a new crash today so that couldn't be it. I was just about to switch to another PSU for testing when I found this post. I have a Shelly Plug S plugged between my server and the UPS, and even another one between the wall and my UPS. It seems very possible that this is the problem! I can't believe I didn't think of this myself. Fingers crossed

So I just recleared my second disk and the exact same behavior occurred. Isnt that odd? This time I had enabled syslog saving to flash, however I cannot find any log message that explains the reason it rebooted. As soon as the preclear was complete the Unraid system is rebooted for unknown reason. Fortunately the disk preclear seems 100% complete since the status is "Precleared". The preclear logs are empty though. syslog syslog-previous

Super happy to hear that and thanks for responding so promptly.

Hey thanks for the plugin! I'm a new user and haven't spun up Unraid fully yet, however I just bought a new disk that I wanted to preclear/test before starting my first array. I used this plugin and it all went smooth, took a few days (18TB disk) but upon completion the whole Unraid-machine rebooted and I don't understand why. It rebooted around the time the preclear was expected to complete but I was not around to see it real-time. Unfortunately the Unraid logs are reset (which I read is normal behavior) and there are no /flash/preclear reports/ folder, so I am not fully sure that the preclear went through alright. Anything I can do at this point? Any clue why the reboot happened? I don't want to have to rerun the preclear to put unnecessary stress on the disk. The UD Preclear GUI says " - Precleared" on the disk, but the logs are cleared. storage01-diagnostics-20240518-2143.zip
