@Tom-Elliott
This is resolved in latest dev-branch version: 1.5.10.1853
Thanks.

I don’t know whether this is relevant, but I’ve just noticed in my PHP error log the following error after I tried doing a System Compatability check with the Dell XPS:

PHP Warning: ftp_mkdir(): Create directory operation failed. in /var/www/fog/lib/fog/fogftp.class.php on line 499', referer: http://11.211.55.5/fog/management/index.php?node=about&sub=kernel&file=aHR0cHM6Ly9naXRodWIuY29tL0ZPR1Byb2plY3QvZm9zL3JlbGVhc2VzL2Rvd25sb2FkLzIwMjYwMzA2L2FybV9JbWFnZQ===&arch=arm64

@Tom-Elliott
Here’s something else funny—the serial numbers aren’t unique! I have a duplicate…
Two differnt PC’s CAD009 and CAD023 🙂

@Mr_K
Thanks for the help Tom. You got me pointed in the right direction. Everything is working now.

I did a complete Ubnutu and fog fresh install to make sure I wasn’t missing anything and noticed during the installation it was grabbing my WAN IP as the fog server IP and then somehow changing the fog server IP to my LAN IP. So when I clicked on the link from the terminal after it had finished it was 192.168.1.148 however everything was setup “certs, storage Ipxe” ect as my WAN IP 20.21.X.X.

All I had to do was just change the fog settings so the IP’s matched re ran the installer to grab the new files and everything is running perfect now.

@Tom-Elliott Sure…

Running version: 1.5.10.1826

@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!

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?

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.

@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'

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

@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.

@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.
