ConfusedPotato Posted October 13, 2020 Share Posted October 13, 2020 Hello. I've been using the same unRAID install for almost 3 years now and unfortunately I've finally reached a point where I think I have to do a full reset and start over again since I can't seem to find a solution to my issue. Short sidestory: I'm running 3 Windows Server 2016 VMs on my server: a domain controller, an application server that I use for work related applications, and a "main desktop" machine that I use for daily work related stuff like Outlook, Teamviewer etc. For whatever reason, if only this last VM is _not_ running my server will always eventually freeze, anywhere between from 30 minutes to 12 hours after booting the server/shutting down the VM. I've already disabled autostart for all VMs and that issue still occurs. I've searched far and wide and couldn't find a solution and I'm also not a Linux guru so I don't really know where to look to begin with. There's never any information in the syslog from when the freeze occurs, the server will just completely halt and not respond and all I can do is a hard reset. So to get back on topic: How would I go about creating a completely fresh unRAID install without losing the data on my array? Is it just a matter of completely formatting the same thumb drive, installing unRAID on it again and then just adding the drives back into the array? Are there any tutorials on that out there? Thanks in advance for any help. Quote Link to comment
JorgeB Posted October 13, 2020 Share Posted October 13, 2020 Backup current flash, recreate it using the USB tool, restore only super.dat (disk assignments) and the key file from the backup, both in the config folder. Quote Link to comment
ConfusedPotato Posted October 13, 2020 Author Share Posted October 13, 2020 Alright, I'll try that then, thanks! Quote Link to comment
trurl Posted October 13, 2020 Share Posted October 13, 2020 Seems a little drastic though and not clear how it could help. Maybe Diagnostics would give us a better idea what the problem is. Go to Tools-diagnostics and attach the complete Diagnostics ZIP file to your NEXT post in this thread. Quote Link to comment
ConfusedPotato Posted October 13, 2020 Author Share Posted October 13, 2020 I attached the diagnostics. I've tried many things already like disabling all Dockers, disabling libvirt, swapping RAM, the issue keeps happening. As soon as it crashes even the screen is frozen and only a hard reset works. I've ordered some cables and adapters to hook up the serial port to a separate PC to see if it spits out a kernel panic or something but the stuff will take a day or two until it arrives. jibril-diagnostics-20201013-1334.zip Quote Link to comment
JorgeB Posted October 13, 2020 Share Posted October 13, 2020 Take a look here, at the idle power setting and at the officially supported RAM speeds, you are overclocking the RAM for your CPU, it's a known issue. Quote Link to comment
ConfusedPotato Posted October 13, 2020 Author Share Posted October 13, 2020 Okay, thanks. I've set the RAM speeds from 3200 down to 1866. I'll report back if it freezes again within the next 24 hours. If anyone has any other possible solutions for those freezes I'll gladly try them. Quote Link to comment
ConfusedPotato Posted October 13, 2020 Author Share Posted October 13, 2020 So it just froze again. Have to make a slight correction to my earlier statement, on the monitor that's hooked up to the server I can see the login prompt and the cursor is blinking, but it's not responding to any inputs.

JorgeB Posted October 13, 2020 Share Posted October 13, 2020 Did you also change the power supply idle control? Quote Link to comment
ConfusedPotato Posted October 13, 2020 Author Share Posted October 13, 2020 Where are those power idle settings? Quote Link to comment
JorgeB Posted October 13, 2020 Share Posted October 13, 2020 In the BIOS, make sure it's up to date. Quote Link to comment
ConfusedPotato Posted October 13, 2020 Author Share Posted October 13, 2020 Okay so I found a "power supply idle control" setting in the BIOS with the options "low current idle", "typical current idle" and "auto". It is currently set to "auto", should I change that to something else? Quote Link to comment

ConfusedPotato Posted October 13, 2020 Author Share Posted October 13, 2020 Ah, sorry, I read everything except that part... will report back if/when it freezes again then. Thanks. Quote Link to comment
trurl Posted October 13, 2020 Share Posted October 13, 2020 Sounds like you may be on the right track now, but just thought I would comment on your original proposal. 7 hours ago, ConfusedPotato said: full reset and start over again This is often asked, but 3 hours ago, trurl said: not clear how it could help "Clean install" is a common "solution" in Windows folklore, but I've never needed it in Windows. In the case of Unraid, if you boot in SAFE mode (which results in no plugins loaded) and also don't load any VMs or dockers, then that is effectively a "clean install" of whatever release you are running, because Unraid runs in RAM. It installs itself fresh from the archives on flash into RAM at each boot. So, if you are keeping your data I don't see how "starting over" can have any effect that couldn't be more simply accomplished by removing addons. Quote Link to comment
ConfusedPotato Posted October 13, 2020 Author Share Posted October 13, 2020 Hm, that makes sense I guess and maybe I'll try that if the server happens to freeze again. Thanks! Quote Link to comment
ConfusedPotato Posted October 14, 2020 Author Share Posted October 14, 2020 Update: So the server has been running for over 24 hours now without any issues. So I guess it really was that power supply idle setting that's been messing with me the whole time. Thanks again everyone for the quick and helpful responses! 1 Quote Link to comment
