Grub Error

[cirsten]

It's important to remember that hardware information is extremely important when diagnosing problems so please make sure to include this information if you need help troubleshooting a problem. This includes:

• Motherboard make and model - Dell DH57M01
• CPU make and model - INtel i7 860
• RAM quantity 16 ddr3
• Hard drives, quantity, model numbers, and RAID configuration, including boot drives - 4 drives: kingston SSD 120gb, 2 HDD - unsure on model nu,bers. Set to ATA no RAID in bios. Not using raid in setup either
• Hard disk controllers - not sure
• Network cards - not sure

At moment on reboot i get an error

"Welcom to GRUB
error serial port com0 isn't found
error: terminal 'serial' isn't found
error: terminal 'serial' isn't found"

Sometimes it will hang there forever
other times will eventually boot into TrueNAS Scale (after 10 minutes)
I've replaced the button battery from a working mobo

The BIOS is a the most recent but still 12 years old

It had been working perfectly until yesterday

It currently is booted up, but as of 2 days ago the TrueNAS Scale version was the most recent (ie GUI said no updates available)

Trying fresh install lasted version of scale as also failed - hangs and the reboots after first screen/selection

This sounds like its trying a serial console or SOL (Serial over LAN) boot, are you trying / do you want serial or serial over Lan? Or do you just want it to boot the the local console?

If you want local only then you can try disabling the serial ports and as well as the serial redirection (if applicable) in the bios. The i7-860 does support vpro so it should have options to support redirection. You can also disable AMT which should also be in the bios somewhere. Disabling these can prevent grub from attempting serial boots in my experience.

On the other hand if you do want console on serial or SOL you will need to figure out the configuration in the bios to enable the correct serial ports and redirection handoff. I have sucessfully done this on a R210ii server but it took some playing around. Also i ran into bug with scale that after doing the install via SOL on boot of Truenas the console was not functioning, although it installed using the correct serial (ttyS0 in my case) on reboot Truenas was trying to send the console over ttyS1 and I needed to login to the gui and change console serial port to ttyS0.

You may also need input from someone smarter then me on how to customize your grub to boot local and not serial.

Thanks for the quick reply.

Certainly not try for SOL boot

Will go into BIOS again try to find those settings

As an aside, now I have time with system back up I've seen than the LAN connection works but it will not connect to the internet. I don't k ow if this information fits with what you just written. Or points or a larger or different issue

Thanks again

I could find either settings for AMT or serial ports in my bios!

It will boot eventually but still no internet access, but LAN working ok. Happy to attach images of BIOS settings if people think to will be helpful
