Packages shouldn't touch any of the files you seem to have problems with. Some other issue caused this, not the upgrade of your packages.

That said, what happens if you enter the boot command?

I got "can't load 'kernel'" error

 

[bsdfans]

and I find updated packages include lua52: 5.2.4 → 5.2.4_1

 

[bsdfans]

this is a screenshot of packages before i do upgrade

 

[SirDice]

The error is with loader_lua(8), more specifically you appear to be missing /boot/lua/core.lua. The lua52, or any other package, has nothing to do with this.

I got "can't load 'kernel'" error

Ok, there might be more missing. How was this system booted before? UEFI or BIOS boot? Recently upgraded (freebsd-update(8))?

 

[bsdfans]

Thank you so much SirDice, how can I fix this issue, I try to show file cli.lua and core.lua, but I can't

How was this system booted before? UEFI or BIOS boot?
This is a remote server, I think it is UEFI

Recently upgraded (freebsd-update(8))?
no

Recently upgraded (freebsd-update(8))?

and/or updated the zroot pool via zpool upgrade but didn't update the boot loader?

 

[bsdfans]

and/or updated the zroot pool via zpool upgrade but didn't update the boot loader?

No, I just ran "pkg update" and "pkg upgrade"

 

[bsdfans]

It is urgent, I am online wait for help

 

[bsdfans]

Currently I did the following step
1. Boot from Live CD (13.0)
2. ran zpool import
zpool import

mkdir /tmp/zroot
zpool import -R /tmp/zroot zroot

But I still can't find and access /boot on my /tmp/zroot folder. There is another empty zroot under /temp/zroot folder.

What do I need to do on the next step?

 

[bsdfans]

I did the following step, but /tmp/root is empty. It seems mount failed, but I don't get any error messages.

mkdir /tmp/root
zfs set mountpoint=/tmp/root zroot/ROOT/default
zfs mount zroot/ROOT/default

 

[bsdfans]

df -h , show zroot/ROOT/default mounted on /tmp/root

What do I need to do on the next step, Thanks

 

[bsdfans]

Oh, it mounted to /tmp/zroot/tmp/root folder, but I confuse this, I thought it should be mount to /tmp/root.

Now I can access server folder.
How can I fix this boot issue? Thanks

 

[bsdfans]

/boot/lua folder include all files

all files aren't empty.

Can I run

gpart bootcode -b /boot/pmbr -p /boot/gptzfsboot -i 1 ada0

to fix it?

It doesn't work, same error message when the server reboot

Solved - LOADER.LUA file not found

I have burned at least 6 DVDs of the ISO FreeBSD-12.1-RELEASE-amd64-dvd1.iso, using every iteration of method I can find, and attempting to boot from any of them BEGINS the boot process, but terminates with "?" and "...BOOT\LUA\LOADER.LUA not found", yet examining the distro finds that file and...

There is one comment that may fix your issue, but I am not sure of that at all, so be careful, read the entire thread before doing anything and look also at the bug reports:

LUA ERROR: Can not open /boot/lua/loader.lua

running into the same problem here. Thinkpad X1 Carbon 5th gen, currently with Arch Linux on it. Tried -CURRENT, 12-STABLE, -RELEASE memsticks and disc1s, none worked and all gave me the same error.

Side note, your server is on 13.0-RELEASE, it's out of date, 13.3 is the last one.

If you ran pkg upgrade successfully, you're not on 13.0-RELEASE. I think this is the version of your boot media. You show an I/O error trying to read the file cli.lua. I would try a zpool scrub. As you are on a ZFS mirror, you have a chance to correct some errors if errors there are.

By the way, you don't boot on EFI but on legacy BIOS if I trust what gpart shows.

 

[bsdfans]

Thanks gotnull

I find the problem, there is a coretemp.ko file on the /boot/kernel. I can't find core.ko

and I also find amdtemp.ko and ow_temp.ko

server's version is FreeBSD 13.0-RELEASE-p13 (GENERIC) when I ran pkg upgrade.

I can open cli.lua file from zfs file system on live CD, so I think the file is well

you should try the
lsdev
command while in the boot loader; it will help to identify devices that can be booted from.

I cp the kernel folder to kernel.new, then I restore the kernel folder from kernal.old folder. Same error messages received when server reboot
