Home assistant will no longer boot

Hi,
I have Home Assistant installed on an old PC, and it had worked perfectly. All of a sudden there were no response in the system, I checked the screen and it was an error message stating out of memory. I did a power reboot - thereafter the system will not start. It will boot and it looks fine but then I get “FAILED Failed to start Docker Application container engine” thereafter a lot of other error messages and soon it reboots! I have inserted some filmed screen shot.

What can I do to fix this, my wife can not operate some of the lights, so this is an extremely severe situation for me (and the future existence of home assistant in my house :frowning: )

In my Gdrive I have a snapshot called “Core_2022.8.2.tar” from the 15:th of august (1.62 GB), I am not sure how this works, but in worst case, can I use that file to and restore the complete computer?

The screen just before it reboots

I don’t use home assistant os. You probably are using this in vm?
Can you mount it single user mode and do file system check.

No, it is not in wm the PC boots directly to homeassistant (i.e. no windows).

It seems not to respond to any key presses, so I have not been able to do anything

From the log you provided its obviously that it didn’t start docker and supervisor.
Can you go to console by pressing ctrl+f1 ?
If you can and file system is mounted you should be able to log in with username and password

Unfortunately it did not, I tried pressing many combinations of shift alt and the F buttons, generally no response, however when I randomly and brutally pressed many buttons I got a sign in test on the screen, I did not press anything and the computer rebooted after like a second

You’re saying that it is an old PC. I would get a bootdisk somewhere first and verify that the hardware is still OK. This could be any Linux bootdisk, but there are more specialised tools as well.

A thorough disk check first and then a memory check.

I removed the disk, moved it to another computer, deleted a folder with video recordings and remounted the disk → and thereafter it worked again!!!

So was this the case where no boot because the disk was full?

I think so, as it booted after I deleted a lot of video recordings - that was the only change I did

So you don’t have a separate partition for a swap file. I have 8 gb of ram + 4 gb swap file. Just in case. Never reached 4 gb.
