Hello 

Let us know the actual state. Cobbler files is not part of db backup, that said, it's expected the similar behavior (sure, if you restore the cobbler files in place).

Hi, 

so cobbler check return : 
>> 1 : some network boot-loaders are missing from /var/lib/cobbler/loaders, you may run 'yum install cobbler-loaders' to download them, or, if you only want to handle x86/x86_64 netbooting, you may ensure that you have installed a *recent* version of the syslinux package installed and can ignore this message entirely. Files in this directory, should you want to support all architectures, should include pxelinux.0, menu.c32, elilo.efi, and yaboot. The 'yum install cobbler-loaders' command is the easiest way to resolve these requirements.

I don't use networkk boot or debian distrib, so there is only the point 4 which maybe a problem? 


cobbler sync return :

Nothing change about my error on kickstart profile. 


I'll try to reinstall new server and restore backup.

What happens, if you run 

cobbler check 

and 

cobbler sync 

on the command line?
