@mashina Ah, thank you for that and sorry for my denseness. Indeed this is a bug and I’ve replicated and figured out where this is occurring.

I have pushed a few mroe adjustments in an attempt find and fix more bugs (thanks AI review and whatnot)

Please pull and let me know if there’s any other issues.

@Tom-Elliott Sure…

@Tom-Elliott Thanks for the clarification! I’ll try upgrading to the latest stable version, I was planning on doing this anyway.

I’ll look into the Persistent Groups plugin and see how it works!

@Mr_K This seems to be a routing issue:

Your fog server lives at 192.168.0.3

Your machine is getting an IP of 192.168.1.148

Your router providing 192.168.1.X is likely unable to route 192.168.1.X -> 192.168.0.X

Fresh install using ver1.5.10.1826

Works perfectly. Can register hosts as normal

Maybe a bug with 1.6.0… hopefully if anyone else experiences this issue this might help

@bruno67

Are you sysprepping the image with all OOBE options set to be skipped before capturing it with FOG?

@gabriel-pissoto

I often record this with a phone then you can pick out the error in that micro flash of text.
I think most of the time picking a different X.pxe file resolves this for me.

@Nono Without going through the web interface you can check the file in /var/www/fog/lib/fog/system.class.php.
Toward the bottom of the file there is a line that start with define('FOG_VERSION'

@bond007fink A new version of ntfs-3g, which is the parent package for ntfsresize, has finally been released last week. That’s after 4 years of no updates. If all goes well, I will be doing an experimental release this weekend with the newer package.

As @Tom-Elliott stated, this is not an issue with FOG itself, instead FOG relies on tools like ntfs-3g and partclone to handle all the NTFS filesystem changes. Hopefully this updated version fixes your issue.
I will update the thread once the experimental release is available.

Managed to figure it out after looking in the wiki for instructions to uninstall FOG with the intention of reinstalling it. Delete that file, delete the fogproject user, and run the install script again. Now it works.

I have the same HP Z2 G1i – it works for me with
sanboot.PNG
“SANBOOT”
The BIOS also seems very finicky to me—I even disabled all NVMe devices and Windows and enabled only network boot—but Windows resets the setting. Setting a BIOS password didn’t change anything.

@hammerc807

This is what I had to do, was in the same boat.

Go to /opt/fog/.fogsettings

Remove the sysv-rc-conf entry from the packages line from there. (Reference: https://github.com/FOGProject/fogproject/issues/797)

Lower down in the same file, set “php_ver=‘8.2’” to “php_ver=‘8.4’”

Exit and save.

Then I had to remove symlinks in Apache that were using the old php modules:

sudo unlink /etc/apache2/mods-enabled/php8.2.conf
sudo unlink /etc/apache2/mods-enabled/php8.2.load

Then add the new links:

sudo ln -s /etc/apache2/mods-available/php8.4.conf /etc/apache2/mods-enabled/php8.4.conf
sudo ln -s /etc/apache2/mods-available/php8.4.load /etc/apache2/mods-enabled/php8.4.load

@Tom-Elliott

This is fixed, too, and can be marked as solved. The reason was stale WOL power action. I deleted those manually from the DB, and the CPU went back to normal.

I’m not sure about the SSH and replication issues, but I deleted my physical storage node, and I’m not seeing those anymore.

@mashina
I’m still having huge problems. Updated Fog. Rebuilt the Windows 11 image. … Windows 11 changes the boot order.
The image works for a few days—then it stops working.
Multicast only works sometimes—just now the image worked with one computer, but not with three in multicast—it just stops at 94% for no reason. What surprises me the most is that with this computer, only BOOT EXIT TYPE: SANBOOT works. I don’t understand much about this, but it seems wrong to me.
