Ubuntu Image for FOG Clients

[fogubuntu]

@Wayne-Workman Yes, I tried all the exit types. I changed this in the following location:

FOG Configuration > iPXE Boot Menu > Exit to Hard Drive type

[Wayne Workman]

@fogubuntu That’s just the default for newly registered hosts. Change the setting for the host you’re working with in Host Management. Pictured below.

[fogubuntu]

@Wayne-Workman I did change it there too. Changing in the default for newly registered hosts worked the same way. Some options resulted in a blank screen with a blinking cursor and some had a message saying Starting cmail()... and nothing happened.

[Wayne Workman]

@fogubuntu This is interesting. Can you run some commands on your reference machine you’re working with (on it’s OS) and get us the output so we can see how the disk is laid out please? Please copy/paste the output into a code box.

lsblk
pvdisplay
vgdisplay
lvdisplay
df -h
fdisk -l

[fogubuntu]

@Wayne-Workman Following is the output for df -h:

@fogubuntu Looks like a GPT type disk, you should be using the UEFI exit types. Please try all of those on the host you’re working with.

[fogubuntu]

@Wayne-Workman I did try all the exit types but I will give this another shot. What is the difference between Host BIOS Exit Type and Host EFI Exit Type?

I did also change the boot type on the client machine’s BIOS to UEFI.

[Wayne Workman]

@fogubuntu said in Ubuntu Image for FOG Clients:

What is the difference between Host BIOS Exit Type and Host EFI Exit Type?

The BIOS exit type only applies to BIOS type systems. So this is the setting used if it’s operating as BIOS. If the system is UEFI, then only the EFI exit type setting is used for that system.

I did also change the boot type on the client machine’s BIOS to UEFI.

When and on what? The reference machine? The destination machine? Before capture? After capture? Before deployment? After deployment?

I’m thinking this whole thing may be a mix-up of system settings. Here’s some rules:

If your reference machine is operating in BIOS mode when you capture the image - then all machines you deploy this image to must be in BIOS mode for it to work right.

If your reference machine is operating in UEFI mode when you capture the image - then all machine syou deploy this image to must be in UEFI mode for it to work right - and secure boot must be disabled.

@Wayne-Workman said in Ubuntu Image for FOG Clients:

I changed the setting on the destination machine after deployment.

Using the same settings as the reference machine did not work either.

[fogubuntu]

@Wayne-Workman I used the same settings as the source machine on the clients and I still get the blank screen or Starting cmain() message and the OS won’t load.

Is there any other settings I should look into to fix this?

[Wayne Workman]

@fogubuntu you didn’t run all the commands that I previously requested - I need the output of those to determine if your using lvm or not. Fog does not support Resizable lvm - the image will not be usable.

[Tom Elliott]

You’ve tried “EFI Exit” with rEFInd? This really doesn’t seem to be a problem with LVM or disk information, directly.

It really really feels like it’s trying to boot across incompatible types.

Please try network booting using EFI by enabling the Network Stack and PXE Network Stack. Then try setting the “EFI Exit” to rEFInd.

This will mean you need to use one of the EFI labeled boot files, but this can typically be automated.
