Good day fellow Unraiders

I come to all of you in desperate need of help, assistance and guidance as I am at my last strand of hair with my server. Ive been using Unraid for some years now (approx 6 or 7) and all by following mostly YT vids. Ive gotten my server running quite well until a week ago when a simple drive upgrade put my machine in such a state that it cant even complete a Parity sync or stay up/stable for a few hrs.

I've been banging my head for days trying to get this sorted out. I did some reading and online post and AI suggested that most times the issue is with either RAM or insufficient power. 2 days ago I put a new and larger PSU on it and started it, everything looked great until it actually took less time to freeze than before. Today (09/26/25) it completed and passed a over 24hrs Memtest on RAM without failing any test or pattern (64gb). Afterwards, I disconnected some components and left only the data drives and the parity drive i want to use; started the server in Safe mode and withing i set up the disk in the order they go and ever started the array in maintenance mode (figured it would reduce the chances of anything causing issues). Sync said it would take approx 14 hrs to complete and with about 8 hrs left (last I checked), i went have dinner and when I came back, it had crashed/frozen.

As I mentioned, Im only good as far as those vids have taken me but Im completely lost when it comes to checking and troubleshooting. Ive been in the forums before and I seen how the first thing asked is the logs which I think Ive attached the correct ones. I can provide other info that may be required or necessary but can someone please help me?

I thank everyone for just taking some time and reading thru this post.

Make sure this has been taken care of, even if it wasn't a problem before:

Good day and thank you for your info. I updated BIOS and made the changes suggested in your post. I then restarted in Safe Mode and started a SYNC but it froze again by the 8% mark. Im wondering if its something with the drive or something in config that may have changed. My main concern is not loosing the data in my storage drives. im trying to complete a Sync in order to replace some drives that gave SMART error.

Edit: 👇🏻

After the previous freeze, I restarted and put another sync to run and this also froze at a different mark. See pic. Unfortunately I couldn't get syslogs since I had to force-shut the machine.

Enable the syslog server and post that after it happens again.

I started a Sync yesterday (09/28) and left it running. It said it would take approx 14 hrs to complete. I checked it thru the day thinking that it may have frozen but to my surprise, it didnt. Last time i checked it was at approx 9pm and it was at the 80% completion mark but still running. This morning, i woke to a command prompt login page as if it had restarted on its own (one of the things it does if it doesnt freeze) but when i logged in, the parity drive icon was green instead of orange. Im not sure if it actually completed but it gave a notification that it did and found no errors. Im hesitant to believe its a proper parity but i shutdown the machine and extracted the syslogs and the last diags. there were 2 syslogs with today's date so i copied both.

Misspelled word

If the parity is green, the sync finished, but post the persistent syslog to confirm.

Also, note that if the server is rebooting by itself, that's almost always a hardware problem.

Hello again. During our previous talk; while not running in Safe Mode or maintenance, i left the room and when i returned, it had frozen. Im attaching the syslog from the drive again and will check on the settings. Also, I started the machine only using one of the RAM sticks to do the stability test and see if thats the issue.

Ive just attached the persistent syslog

syslog-127.0.0.1.log

I'm afraid there's nothing relevant logged, and this also points to a hardware issue, if you have multiple sticks try using the server with just one, if the same try with a different one, that will basically rule out bad RAM.

Hi

I did that and tried all 4 sticks individually and the server froze with each at different intervals which got me now confused since they passed the Memtest but I moved on and ordered new RAM sticks and installed them. Running a Sync now since I also installed a replacement drive for parity. It's currently running on Safe Mode and Maintenance mode at the same time (that's how the last Sync was able to complete) and should be done in a few hrs.

Ill provide an update once it finishes or sooner if it crashes/freezes again.

If the server still crashes with multiple sticks used individually, RAM is likely not the problem.

Time for an update

After much troubleshooting, components testing and buying parts, it turned out that the issue was a faulty MB. I bought new RAM and the issue still happened, changed the CPU and same, changed HDDs just in case and no different. Bought and installed a new MB and haven't had an issue. No idea how the MB went bad or what in it is but that's what it turned out to be. As JorgeB stated above, logs didn't give any specifics but it all pointed to hardware. Identifying which was the headache but that's all past now.

Hope anyone who reads this gets to identify their issue faster than me and cheaper as well LOL.

Thanks for the help JorgeB.
