Intermittent rebooting on startup

TrueNAS General

TrueNas Core Version: TrueNAS-13.0-U6.7

I ran a scrub of one of my “video” pools “(System Dataset Pool) ONLINE | 38.92 TiB (91%) Used | 3.82 TiB Free” I know it’s nearly full, but it’s only ever written to once a day, it’s files are then read by no more than 2 people at any time.

I noticed a bit of slowness and buffering after the scrub, but that might have been my imagination / congetion, but it definaltey buffered, something it never does.

The server shutsdown and has it’s power turned off at night due to the electricity costs. I turned it on manually today, usualy it’s timed, being a bank holiday, and it rebooted twice with a kernel 12 error, Here’s a screen shot

Actually I took a video, but swore a little at the end when it failed so I can’t put it up here. I went to retake the video and it came up fine, so I’m leaving it up, and will have to raid the piggy bank to pay for the electric.

I’m going away on Wednesday at midnight for 10 days, and really want it up while I’m away, it’s kind of important for this one “week” of the year.

I’ve put a couple of logs, the messages, console and debug. I added a txt extension so I could upload them

Thank you very much for your help. Where can I look for clues to the cause?

What device do you have the OS installed on? I can’t see that in your sig.

Hi, thanks for looking at
This.

The os is installed on a crucial ssd.
If it’s failing I could try
Cloning it to another one or put in a pcie nvme adapter card and put a nvme on that.
What would you recommend?
Thanks

Power supplies are a common failure cause. Often they don’t shut down suddenly but degrade slowly over time as capacitors leak or degrade.

I had frequent strange data errors with a mini itx system where the power supply that came with the case was underpowered. Changed the 150W part with a new 350W part, and all problems went away.

I’d first run a mem test and make sure your RAM is ok. After that I’d consider trying another boot disk and take it from there.
