Let me answer one question at a time.
#1:The only limit you would have for image size would be based off whatever space is available in storage.
#2: Are you asking if you can transfer images from one server to another? Is so then yes. You just need to make sure everything in the web GUI fo the image settings as on the original server as it is for the server you are transferring it to (image name, operating system compression, etc.)
I am trying to deploy an image to a machine that requires a USB to Ethernet adapter. I have the adapter registered as a host in FOG and I have the kernal arguments set. I have been able to do this before on version 1.4.4, I am now on the latest version and not able to do so. This is the first time I’ve had to do this on the latest version. When I did this with version 1.4.4 I used this link as a reference:
https://wiki.fogproject.org/wiki/index.php?title=USB_NIC_(usb_network_adapter)
So now when I go to deploy the image to the machine it will PXE boot to the FOG menu and I can select the image, it will go through bzImage…ok and init.xz… just fine, but after that its just a black screen. I’ve tested other known good images on this ethernet adapter with the same result.
Also here is a Ethernet Adpater I am trying this on with how I have it set in FOG.

Also I ran a syslog tail here is the results below the machine in question is getting a .106 IP Address:

This is the type of adapter I am using:

I am guessing there is something different in the new version with the settings that I am just not aware of.
@Joe-Gill Try looking into your apache settings and look at logs. Here is a an article on how to do that, might vary depending on the web service you are using for web server.

Updating the FOG server to the latest image appears to have resolved the issues. Good thing is did not have to modify anything after the update all models appear to be imaging successfully. 
@george1421 I am not sure if this is related or not but I went back up through the command line from the update and it looks like there was a error when doing the git pull command
Should I maybe go through the install again with doing a git reset --hard?
@george1421 @Sebastian-Roth I downloaded those files and rebooted the server and still experiencing the same error. Forgot to mention that after doing this update this error now occurs on all models.

@george1421 since I am not able to download/install them within FOG. Would it be possible to download the kernels from somewhere else and then just copy them over to the directory?
@sebastian-roth here is the results of that command:
@sebastian-roth yes that is what I went through, and I verified the ramdisk size and didn’t have any luck. I remember having to set the ramdisk to 275000 a year ago because of an issue back then.
We did test with the same computers as used before the update, so it is kinda weird.
@george1421 It does not look like it is downloading. I checked that directory and the downloaded one is not their going off the modify date.
@george1421 When I go to hit install for that Kernel it does not load anything.
@sebastian-roth I ended up having to do the update, because our ramdisk size was correct and we were still having the issue. We but a computer up to pull an image and after you go through the PXE menu to select a image it gives this error.

We verified the interface and dhcp is up. Any ideas?
We just all the sudden started receive a failed partition error on all our Lenovo T470 models. It appears to be only with our 2004 Windows 10 images and above, 1909 images work just fine. This is the error we receive.

The image is set to Single Disk - Resizable, Partition Everything, Compression 10, Partclone Gzip. We are running FOG version 1.5.6.5.
Since it only seems to be the newst version of Windows 10 images having this issue could it be that we simply need to update to the latest version of FOG?
@Sebastian-Roth Machine was working fine after re-image and then started having performance issues mainly with Office and did Office repair. We are probably going to pull machine back and do another RAM test along with Lenovo diagnostics. Maybe just even replace RAM.
We do want to upgrade but we have been pretty swamped withe people working from home, so hopefully we can do this when things settle down
